Random Daily Heroic: Deadmines - 4/22/11

Today my random daily heroic was Deadmines on Wranngar. This dungeon can be kind of tricky if you have a bad group or a group with too many people that aren't familiar with it.  

We had a decent group though so we didn't have many problems. We got through the trash ok then had one person die on the first boss. You have to watch out for the wall of fire, it really hurts. This fight can be tough on melee fighters because you have to be so close to him when the wall of fire is centered on him. We got him down anyway without any problem.

We cleared some more trash and made our way to the next boss in the workshop. We had no problems in there, we cleared the two trash mobs, killed the boss' lackey, then killed the boss.

We cleared the trash from there to the foundry. The foundry is where things can, and usually do, go bad. We "converted" the mobs down below then engaged the boss. As usual we fought him on the ramp. As a melee this can be a tough fight because of the AoE's he does. I made sure to run away every time I saw him casting one of them. The tank died at one point but I battle rezz'd him with 100% health and got him back into the fight. We got that boss down without any more deaths.

We cleared some more trash and made our way onto the boat. Ripsnarl is the first boss you have to fight on the boat and possibly the hardest too. We didn't have any problem with him this time though and got him down. Some people like to tank him inside the cabin there but I don't think that is a good idea. If you tank him inside you have to get out very fast when he dies or Cookie will spawn on top of you and you have to go from one boss fight into another. That is kind of stressful on the healer as the Cookie fight can be heals heavy. I have seen it happen more than once.

We got Cookie out of the way after that and then it was time for Vanessa. We did the nightmares part and lost 3 people in the beams. That can be tricky but it has been a long time since I have died on that part. We got the dead rezz'd and headed in to save the family. It was rezzing the dead that did us in, we wiped on the last mob before Vanessa when the time ran out. When we got back we took down Vanessa without any problem and completed the dungeon.

I got my 70 Valor Points and also won the Chaos Orb which was pretty nice. I did a couple more randoms after that and won one more orb.

Random Daily Heroic - Blackrock Caverns 4/20/11

Today I got Blackrock Caverns for my random daily heroic on Wranngar. This instance isn't too bad as long as you have a decent group that knows how to do the second boss.

After clearing a couple groups of trash we were ready to take down the first boss, Rom'ogg Bonecrusher. This boss has a few moves but the most dangerous is the binding chains he puts on you and the skullcracker he does immediately afterwards. It is very important that you dps down the chains as fast as you can so you have time to get away before he does the skullcracker. We wiped on this boss because someone got too close to a group of mobs the tank didn't clear, sloppy playing combined with sloppy clearing. After we got by this boss we cleared some more trash which brought us to Corla, Hearld of Twilight.

This is where a group has to work together. I have seen so many wipes trying to take this boss down because people don't know what they are doing. It is not a hard boss, but everything has to be done right. You need three people to block the beams. As you are blocking the beam you are building up stacks, you need to step out of the beam when you hit 80 stacks. I usually start moving around 75 stacks. You stay out of the beam until the stacks wear off then step right back into the beam. Repeat this until the boss is down. Simple. I have seen so many wipes on this boss.

Some more trash brings you to Karsh Steelbender. Simple boss. Just run him through the fire once in awhile and dps him down. DPS goes up as the stacks do so you can burn this boss down pretty fast.

Once you have Steelbender down you have some more trash to get you to Beauty. Beauty has 2 smaller dogs with her, Lucky and I think the other one's name is Buster or Spot. There is also Runty in the back but you don't need to deal with him. Use some kind of CC on the two smaller dogs, remembering to refresh it once in awhile, and take the boss down, pretty easy stuff.

A little more trash brings you to the last boss, Ascendant Lord Obsidius. He will have 3 "followers" with him that someone in the group will have to kite. I have found it pretty easy to kite them in Bear form on my Druid, with my Hunter and it looks like Mages can do it easily also. Once in awhile during the fight he will switch places with one of his "followers" so whoever is kiting will need to pick that one up while the dps switches back to the boss. Usually not a hard fight.

I completed this as my daily and received my 70 Valor Points as well as winning the Chaos Orb. I now have 17 Chaos Orbs in stock, I think it is time to make something.

Random Daily Heroic - Shadowfang Keep 4/19/11

I got Shadowfang Keep as my random daily heroic again today on Wranngar.

I got lucky and got another great group again today. We burned right through the place taking out all bosses on the way. There were two deaths this time, both the same person, an undergeared Shadow Priest. That was not the Healers fault though, the Priest had low health and a noticeable lack of experience. SFK is one of the dungeons that on normal is really low level and then level 85 on heroic so that happens from time to time. I know it has changed dramatically since I did it on normal when my toons were low level. They changed some of the low level dungeons around for cataclysm and then made a strictly heroic version for 85's.

The first death was at the first boss, Baron Ashbury, which is understandable. The first boss does a move called asphyxiate that brings you down to literally around 1 HP so it is easy to lose someone there or even wipe. He has a few other moves but most of them are interruptable.

The Tank on this run didn't pull the large mobs from outside to the inside so we could fight them, we fought them outside in the courtyard which is unusual. The problem you can have doing that is someone getting feared into other mobs but we got through it without that happening.

We made our way into the kitchen/dining area, took out the trash, and killed the second boss, Baron Silverlaine. That has always seemed like an easy fight to me on heroic.

The next boss in the lineup is Commander Springvale. He can be pretty tough as he has a few moves that deal up some good damage. He main attacks are Word of Shame, Malefic Strike, Desecration and Shield of the Perfidious. A lot of groups will skip this boss or wipe on him a couple times and skip him but the last couple groups I have been in have taken him down without a problem. This was the second and last death for the Shadow Priest.

Next was Lord Walden. He has a couple of toxic attacks that can deal out a lot of damage. There are a couple simple rules to remember for his toxic attacks. Green keep moving, Red don't move. Pretty simple. We had no problem with this boss. This is where I topped 15k dps yesterday, today I did 14.8k, not bad but not 15k either lol.

The last boss in this dungeon is Lord Godfrey. This is a boss that a group is either going to be able to work together on and get down fast or wipe on a few times and get him down eventually if the group doesn't fall apart. It takes some coordination and quick wits to get through this boss.

Lord Godfrey has a few attacks starting with Pistol Barrage. That is when he will fire a pistol barrage which fires out in a cone from the boss inflicting 27000 shadow damage a second to anyone inside the cone and lasts for six seconds.

His next attack is Summon Bloodthirsty Ghouls which will summon six ghouls over three seconds.

Probably his most lethal attack is Cursed Bullets which is a curse he will put on a target. This can be interrupted but has a one second cast time. This curse lasts 15 seconds with the damage increasing over time. The last five ticks of this curse will hit you for 10k, 20k, 30k, 40k and 50k damage, that's 150k damage over five seconds. This curse needs to be dispelled as soon as possible. Today we had a Paladin Healer who can not remove curses so I had to decurse on that one. If you are going to remove this curse you will have to have a Druid or Shaman in the group. Mages might be able to remove curses too, I'm not sure.

His last attack is Mortal Wound that he will put on the tank. This attack causes 1500 damage per second and reduces healing received by 10% for eight seconds, this is stackable.

We got him down pretty quick and easy getting me my 70 Valor Points and the Chaos Orb. It was a pretty easy win for the orb today, I was the only one who could roll on it. I found out after I left the dungeon and went to sell my loot that I had won just about every roll in there including the two items the last boss dropped plus the Chaos Orb. A lucky day for me.

Feeling Crabby? - Random Daily Cooking Quest 4/19/11

Today the daily cooking quest from Robby Flay (50,71) in Stormwind City was Feeling Crabby?.

This one had me heading to the canals in Stormwind to catch 10 Canal Crabs. I used to think Cheese for Glowergold in Dalaran was hard because the Half Full Dalaran Wine Glasses were so small and hard to target but these are small and moving so it is even worse.

I jumped in the canal on Wranngar and switched to swim form, so I wouldn't have to keep surfacing for air, and started swimming around. The Canal Crabs are just wandering around and you have to click on them like you are looting them. It only takes a few minutes to get the 10 you need if there are not a lot of people doing the daily at the same time. If there are it can take awhile.

Today there was no one else doing it so I got it done in a few minutes. Once I had the 10 Canal Crabs I needed I headed back over to Robby Flay to turn them in. Today he gave me 9g40s and 2 Chef's Awards. I would have also gotten +1 to my cooking skill if my cooking skill wasn't already maxed at 525. I am only doing this now for the Chef's Awards so I can buy the rest of the Cataclysm cooking recipes.

Random daily Heroic - Shadowfang Keep 4/18/11

I had a little trouble getting my random daily heroic done on Wranngar today, they kept restarting the server half way through. I started a Deadmines run only to have it reset half way through Ripsnarl. I started a Stonecore only to have it reset before the first boss. Finally I got into a Shadowfang keep that I was able to finish.

My dps started off slow in SFK, it usually does when I first enter an instance. Once I got rolling it was ok though. By the time we got to the first boss I was in my groove. We got the first boss down without any trouble. This boss can be kind of scary. I can't imagine what people must think when they are in there for the very first time on heroic, especially the healer. The boss does this thing called strangulation which incapacitates everyone and brings their health down to about 1 HP. I remember the first time I did it, I figured we were going to wipe.

We did all the bosses on this run and I got an achievement out of it. On the next to the last boss, Lord Walden, my dps passed 15k which is a personal best for me on Wranngar. I was a little surprised it happened on that boss as you have to run around when he does certain attacks and that usually reduces your dps.

As I was the only one able to decurse, I had to decurse on the last boss. The last boss has a curse he puts on you called Cursed Bullets. This curse will do a lot of damage if not removed. The last five ticks of this curse will hit for 10k, 20k, 30k, 40k and 50k, hitting you for 150k damage in five ticks. I know I don't have 150k HP to spare or 150k HP for that matter. We got the last boss down without a problem to complete my daily random.

I won the Chaos Orb along with collecting my 70 Valor Points. That enabled me to get my new 359 cloak, Viewless Wings. That cost me 1250 Valor Points. The next item I will be getting is a relic for 700 Valor Points. That will take me 10 days of randoms to get.

Random Daily Heroic - Vortex Pinnacle 4/17/11

Today my daily random heroic dungeon for Wranngar was Vortex Pinnacle. I did it with 2 other guild members, both dps, so we had to pug the healer and tank.

We ended up getting a good Warrior tank and Druid Healer so things went well. My dps was in top form for this one and I was leading for most of the dungeon. On the second boss, Altairus I hit 20k dps with the buff you get from standing upwind. That topped the next highest by almost 10k.


We didn't have any problems with this run, it was textbook and smooth and I got my 70 valor points but lost the Chaos Orb to a guild member. I also lost the next Chaos Orb to the same guild member but got the one after that.

I ended up running a total of four heroic dungeons last night, getting one Chaos Orb and losing on three of them. That is not too bad, I have 12 Chaos Orbs now and that is enough to make a few pieces of gear. I will be getting my new cloak, Viewless Wings, tomorrow after I complete my daily heroic.

Heroic Grim Batol Walk Through

This post will walk you through heroic Grim Batol and the boss fights.

You start by killing trash mobs so you can get to the drakes. Once you have the drakes free you use them to do a bombing run. It is very important to do a good job on the bombing run if you don't want to be in there all day. The bombing run softens up a lot of the trash you have to kill on the way to the bosses and if you don't do a good job you will end up spending a lot more time than is necessary on the trash. After the bombing run you kill the trash between you and the first boss.

The first boss is General Umbriss. He is the easiest boss. He has two main attacks, Blitz and Ground Siege.

Blitz will one shot you. When he is going to cast Blitz he will look at someone and begin to cast, all you need to do is move left or right to get out of the way, there is plenty of time to do this.

Ground Siege appears to be a targetless attack but you don't want to be in front of him when he does it as it is just avoidable damage and it will stun you.

Every so often throughout the fight, Umbriss will call on some Troggs to come help him. One Malignant Trogg and three Trogg Dwellers will spawn the first time. You will want to CC the Malignant Trogg, as opposed to killing it, if you can because if it does not die Umbriss will not summon more Trogg Dwellers, or another Malignant Trogg, otherwise the Trogg Dwellers will continue coming in groups of three every time Umbriss calls them. Trust me when I tell you this is the way you want to do it.

If you do decide to kill the Malignant Troggs, make sure you do it away from other troggs and the boss otherwise they cast an AoE of Modgud's Malice turning other nearby troggs into Malignant ones, and increasing the boss' damage by 100% if it hits him.

After Umbriss you will clear a little more trash until you get to Forgemaster Throngus. This boss walks a beat so keep an eye out for him when you are clearing the trash.

Throngus can be tough and you really have to stay on your toes to stay alive. He has three "equip" weapon attacks he does plus Mighty Stomp which will cause a cave in on top of random players, just move out of the way.

When Throngus equips his Mace he will become encumbered, which will slow him down, but deal a lot of damage. This is where the tank will want to kite him and stay out of reach. During the Mace encounter he will randomly pick a player and do Impaling Slam on them which incapacitates them. His mace will also drip lava while he is walking along so you want to stay out of that.

When Throngus equips Dual Blades he will start doing a lot of damage to the tank through attacks and a stackable DoT. The DoT is magic and can be dispelled.

When Throngus equips his Shield it shoots flames and he is only vulnerable from behind, you are going to want to make sure you are behind him during this encounter. When he is in Shield phase you will be taking a lot of AoE damage from unseen archers shooting flaming arrows, there is nothing you can do about that but heal through it.

Throngus will go through all three of these "equip" phases before he starts again so if the first one is Mace and the second is Dual Blades you know that Shield is coming next, what you don't know is what the fourth "equip" phase will be as they will most likely not be in the same order as the first time.

Some more trash brings you to Drahga Shadowburner. This is the hardest boss in there as far as I'm concerned. He alone is not too bad, but when he is on his dragon, Valiona, he can deal out a lot of damage. He will summon Invocation of Flame and they will one shot you and anyone around you so you will want to make sure to kite them if they are on you or burn them down if they are not. This encounter is in three phases.

In phase one you will want to concentrate on dpsing Drahga and killing the Invocations of Flame. Drahga's primary attack is a Burning Shadowblot that can be interrupted, so if you have an interrupt it will make your healers job a lot easier. Around 25% health Drahga will run over and jump off the platform, landing on a dragon, that starts phase two.

In phase two you will be fighting the dragon. The dragon he summons, Valiona, has an ability called Devouring Flames, a 180 degree frontal attack, and it does just what it says, it will devour you if you are in front of him when he uses it. This is a good fight for melee as long as the tank has the sense to move Valiona out of the stuff that gets put down when Valiona does Shredding Swipe and moves Valiona if an Invocation of Flame is spawning under him. The stuff on the ground slows everyone down who is in it and you don't want to be slowed down if an Invocation of Flame is after you. When Valiona does Devouring Flames you will want to get behind him. At about 20% health Valiona states "I will not die for you Drahga" and leaves.

This takes you to phase three where you finish off Drahga. Make sure to keep an eye out for the Invocation of Flames he will be summoning. With a good group that knows what they are doing it is actually pretty easy to down him.

A little more trash will bring you to the last boss, Erudax. This boss has a few moves. One is Binding Shadows. This will root you in place and heal the boss. If you see him target you move to the side. This debuff is magic and dispellable but why heal the boss? The next move he has is directed towards the tank and it is Enfeebling Blow. It will knock the tank back and put Feeble Body on the tank, just wait for boss to walk back up to the tank.

One of his major moves is Shadow Gale. When the boss casts this you will see a vortex looking circle on the ground, get into it. It is like the eye of the storm. Everyone needs to get into the "eye of the storm" including the tank. Directly after Shadow Gale he will summon two Faceless Corruptors. Everyone, including the tank, will need to dps these down very fast. They will be trying to hatch the eggs along the side of the room which will spawn Dragonkin Hatchlings that will dps the group and heal the boss. You will go through this process several times before the boss is finally down.

I used to think this heroic dungeon was next to impossible but after doing it a few times it is really not that bad. You will need to have a fairly decent geared group that can work together to get through this without too much trouble. I wouldn't attempt it with a group of people with a 329 item level but a group with 335+ item level and up you shouldn't have much trouble.

Good Luck

Random Daily Heroic - Shadowfang Keep 4/15/11

Today my daily random heroic on Wranngar was Shadowfang Keep.

I ran it today with two other guild members so all we had to pug was the healer and one dps. After a couple close calls on the trash before the first boss the healer told us that this was his first time healing a Cata heroic. With that in mind we headed over to the first boss. Healing SFK can be pretty demanding, especially on the first boss. We made it by the first boss without any deaths though and the healer did pretty well. We cleared the trash in the courtyard and made our way to the next boss without any problems. When you are clearing the trash in the courtyard you will want to pull the large mobs back up inside and fight them there as they fear and you don't want them fearing anyone out into the courtyard where they might aggro other mobs. We got the next boss down, skipped the third boss, and finished up without any major problems.

I won the Chaos Orb from that run and got my 70 Valor Points, only 3 more days until I can get my new cloak with my Valor points.

I went on to run 5 more heroics after that, some with guildies and some that I pugged through the random dungeon finder. I ran one Deadmines, two Blackrock Caverns, one Halls of Origination and one Stonecore. I was lagging in my next to last dungeon which was Blackrock Caverns, and I was lagging so bad in my last one, Stonecore, that I could not get away from the third boss fast enough to get away from his shatter move. In Stonecore we had 4 guild members and one pug. The tank from our guild was really new to tanking and it took him a few tries to get the third boss down, but that is a learning experience, that boss is pretty tough. On the plus side he had the routine down by the time we finally got the boss down. The way I dealt with my lag was I just ran away from him after one of his moves when I knew the shatter was coming in a few seconds.


I had a lot of fun running these with guildies and with the pugs too. I used to think the heroics were really hard but now that I have run them all quite a few times they are pretty easy. Grim Batol can be rough if you don't have a really good group but that is the hardest heroic in my opinion.

Random Daily Heroic - 4/14/11

Today my daily random heroic dungeons were Halls of Origination on Wranngar and Blackrock Caverns on Brieanna.

I did Halls of Origination on Wranngar first. The tank on this run had an item level of 330, 11 unenchanted items, 5 missing glyphs, 2 unsocketed items and was missing the Ebonsteel Belt Buckle. This goes back to my always saying that 329 item level is too low for a Tank or Healer in heroics and when you get someone like this, well, they shouldn't be tanking anything.

Needless to say the run was a little rough. I wouldn't expect a healer to be able to keep that tank up at all but the healer we had, one of my guild mates, did a pretty good job. We didn't wipe at all but came close a few times. The tank died a few times, which is to be expected with the way they were geared, but we got through it somehow. I was pretty happy when they went right to the last boss when we got up top instead of trying to do all four, I had enough of a repair bill as it was. I didn't get the Chaos Orb from this run, a Warlock that came in right before the last boss got it...

After that I jumped on my Hunter Bireanna and did Blackrock Caverns. It had been awhile since I was on her and it was like learning to play her all over again. I really need to rotate through my characters more, I don't even want to think what it will be like when I finally get back on my Shaman Breeonna again.

We had a pretty smooth run through Blackrock Caverns, no wipes and the Healer was able to pick up a few items they needed. I was hoping the bow would drop off the last boss but it didn't. The only time I ever see the bow drop is if I am not on my hunter. As Brieanna doesn't have any professions that use a Chaos Orb she wasn't even in the roll for it.

I did get my 70 Valor Points on both toons though and will be able to get my Cloak on Wranngar in 4 more days.

Gomorra - 525 Tailoring

I worked on Gomorra's Tailoring and got it maxed at 525. I was selling what I was making on the auction house so I recovered the gold I had to spend on mats and actually came out a little ahead. That makes four out of five of my level 85 characters that have both their professions maxed at 525.

Now I have to make Dreamcloth to buy the patterns. The Dreamcloth takes 30 Volatiles each piece which seems like an awful lot. Then each epic pattern costs you one piece of Dreamcloth to purchase. Of course after you purchase the pattern you need Dreamcloth to make the item. No wonder the epic cloth pieces go for so much on the auction house.

There are six different patterns to make Dreamcloth and five of them have a 7 day cool down. The sixth one uses 5 Chaos Orbs and doesn't have a cool down but who has that many orbs to throw away? They all take eight bolts of Embersilk cloth and the five that don't use the Chaos Orbs take 30 volatiles each. Dreamcloth is BoP (Bind on Pickup) so you can not buy or sell it.

You also need Chaos Orbs to make the epic 359 items.


Random Daily Heroic - Shadowfang Keep 4/13/11

Today Wranngar's random daily heroic was Shadowfang Keep. I did it with three other guild members so all we had to pug was the healer.

The first healer left before we even got to the first boss, he said we were going too slow... That was ok though, he was a Pally healer and the best healer for SFK is a Druid because they can dispell the curse the last boss puts on you, curse of bullets. That is a nasty curse, the last five ticks hit for 10k, 20k, 30k, 40k and 50k, hitting you for 150k damage in five ticks. I would have dispelled it if the Pally had stayed. We ended up getting a very well geared Druid healer though so I didn't have to.

We had a pretty smooth run, we wiped once when I got feared around the corner and into the other gargoyles when you are outside up on the walkways. I got feared four or five times fighting the gargoyles, it was getting old.

We got all the bosses down though and really had no problems. I didn't win the Chaos Orb but I did get some tips from the healer about dpsing in Kitty. Their main spec was Kitty. I changed my spec around some and changed my rotation but at first it didn't seem like it was better, actually it seemed a little worse but with time my dps started climbing. Hopefully in the long run the new spec and rotation will be better for my dps once I get used to it.

Random Daily Heroic - Deadmines 4/12/11

Today Wranngar's random daily heroic was Deadmines.

As soon as I zoned in the screen came up to queue for a random dungeon. I guess someone didn't want to do Deadmines which is the second hardest heroic in my opinion. Needless to say we couldn't queue for another random because we were all on the 15 minute cooldown. They decided to go ahead and see how far they could get and then requeue when the cooldown was up.

We had no problem and ended up finishing Deadmines. It went pretty smooth. We had no wipes and took all the bosses down first shot. I averaged over 10.5k dps for the entire run and only got beat by the Mage in the group who averaged 12k. We had one person leave before we finished but that was ok as he was only pulling 8k dps. He was replaced by someone who was only pulling 7k though but we still made it without any major problems.

We got past Ripsnarl with ease which was the boss I ended up bailing on last time I was in there after five wipes. We took down cookie with ease and Vanessa with no problem to complete my daily random.

I won the Chaos Orb from that run which was fine by me and also collected my 70 valor points for my random daily heroic. I now have 9 Chaos Orbs in stock for when I need them. I am waiting for a friend to get back online so I can make them some 359 gear.

Random Daily Heroic - Halls of Origination 4/11/11

Today the random daily heroic I completed on Wranngar was Halls of Origination. As you might have noticed I said completed. The first one I was in for my random daily was Deadmines. Deadmines is a tricky one and I would say the second hardest heroic after Grim Batol.

I got in to Deadmines right after the group I joined finished downing the third boss, Foe Reaper 5000. I figured it would be a pretty easy 70 valor points, boy was I wrong. I noticed in the very first fight that the tank, a Deathknight, was looking kind of squishy. The Healer had 103k mana using a flask so I figured we would be ok anyway. Wrong again. We made it through the trash between Foe Reaper and the boat without too much difficulty, but when we got to Ripsnarl, the next boss, things went downhill fast. The Healer was running out of mana about a quarter of the way through the fight, which tells me he had very low Spirit/Regen, I ended up innervating him a few times but it was not enough. To make a long story short we wiped on Ripsnarl 5 times before I finally bailed. I was doing 12k dps which was double what the next highest person was doing, we just didn't have the dps to get him down. Funny thing is we came the closest to getting him down on the first attempt.

After I bailed out of Deadmines I requeued and got Halls of Origination. Once again I didn't get in at the start, I got in right after the first boss. I figured that was from someone either getting what they were after off the first boss and leaving or not getting what they were after off the first boss and leaving. This group turned out to be pretty decent and we only took down the bosses we needed to so it was pretty quick too. I didn't get any gear, any upgrades I get from here on out will be coming from raid mobs/bosses, but I did get the Chaos Orb at the end so I was happy. I also got my 70 valor points for the day.

At the risk of sounding like a broken record, I strongly believe that a 329 item level is too low for a Tank or Healer to be entering heroics. It is too low for a lot of the dps too in my opinion. The bosses in heroics, as well as the trash mobs, have a lot of health and hit hard. Low dps makes the Healer run out of mana because the fights take too long. An under geared Healer is going to run out of mana anyway because they didn't have enough to begin with and an under geared Tank is not going to be able to stand up to the beating required to tank a heroic. If you get a 5 man group of people in a heroic who all have a 329 item level it's just not going to happen.

Buying gear with justice points combined with 333 item level drops from normal dungeons and rep gear can get you an item level of at least 340, why not wait?
