This is part of a series of posts about the role of rogues in Ulduar. The focus is on 10-man raids, but on occasion mention will be made about 25-man strategies as well. This is not meant to be a general strategy guide. It is completely targeted at rogues, their abilities, and their strengths in specific combats. Much of what is written could apply to other melee dps as well.
Razorscale is an optional boss. You can walk right by and ignore her. She’s not so tough, though, so I recommend trying her. AoE dps is helpful for the first 50% of this fight (rogues can do that) and single target dps for the second half (we can do that, too).
Step one - stay out of the blue fire. Thats easy in phase 1, a little harder in phase 2. Don’t try and do anything fancy with it – just avoid it. You will be hit by it on occasion since it is targeted. Just react quickly and move.
Phase 1 is mostly about fighting trash mobs. They spawn out of the drilling machines that come up from the ground. There are three kinds of adds. You need to keep a particular eye out for two of them.
Dark Rune Sentinels are obvious. They are huge viking-looking guys. Avoid them. Their whirlwind can one-shot rogues. Let a tank hold it while ranged dps burns it down. I know that it hurts to let those ranged get a chance at your dps, but its for the best. If a tank is holding a Sentinel, go see what the other tank is doing. If the adds are all being grouped up for AoE, then you can go in and do some damage as long as you are ready to hit Evasion fast if you see him Whirlwind.
The one you want to make a beeline for is the Dark Rune Watcher. He’s a nasty little dwarf-sized guy. His Chain Lightning can do a lot of hurt on a bunch of players, so you want to interrupt that every time. Stun, Blind, Kick… whatever. DPS them down fast. If you are getting splash heals from the raid healers then you may be able solo one of them with a little stunlocking to avoid taking too much damage.
The other trash mobs – Dark Rune Guardians – are unimportant. Pop a few FoK to help clear them out.
While you’re doing all of that, someone in the back of the raid is activating harpoons to pull Razorscale down to the ground. You’ll see raid warnings announcing it. When Razorscale comes to the ground, use your Tricks of the Trade to send your threat to the tank so that you can go all-out dps without pulling aggro. Make sure you choose the right tank – the off-tank may still be holding adds while the raid goes after Razorscale.
Hit Razorscale with all that you have. Pop your cooldowns. The goal is to get Razorscale down to 50% health before she goes back in the air. Unless you’re very very well-geared you won’t do that on her first time on the ground. After a few seconds she’ll throw everyone off, fly back up in the air, and then you’re on trash again until the harpoons pull her back down.
Once Razorscale gets down to 50% health the adds will stop spawning and you enter phase 2. The dragon stays on the ground for the rest of the fight. Help clean up the remaining adds then go to Razorscale. The tanks will be taunting her back and forth, so be careful with threat and don’t use TotT on a tank if its not their turn to hold aggro. Also, they will be kiting her around. You’ll stay behind her or just off to the side. No tail swipes here, but she does leave pools of blue fire which you have to avoid. I like to stay at her side and strafe. Just don’t get in front of her. As long as the tanks do their job, you’ll just follow her around and stabbity-stab her.
If you see the Flame Buffet debuff stacking on you, you can CoS out of it. But its not a big problem if you’re staying out of the fire.
She dies. Screenshot. Everyone is happy. Except Thorim of course. The heroic version of the fight isn’t much different.
