Class requirements

You need 2 tanks for the dragon. If you feel unsecure, you can take 3 as well.

The pull

The pull will be done by talking with the Expedition Commander.

Positions and strategy

The raid will position itself in the circle in the middle of the area. The tanks will stand in front of the raid, each covering the left, middle and right side. Once the talk with the Expedition Commander is done, Mole Machines will appear in those regions and Dark Rune Dwarves will appear from within.

The goal of this fight is to use the turrets at the entrance of the area to pull down Razorscale. Once all 4 turrets are used, she will be drawn to the ground where she will stay stunned for some time. During this time, no additional adds will spawn so dps can soley focus on Razorscale.

The Fight:

While Razorscale is in the air, she will randomly target raid members and spout a blue ball of fire at them. On impact, they will form a pad of blue flames noone should stand inside. You will take considerable damage while standing inside them.

The adds will be drawn together by the tanks so that they can easily be AoE'ed. If a Sentinel happens to spawn he will be killed first and try to be quick. They do the most damage to the tanks and are deadly with their whirlwind attack.

Because no adds are going to spawn when she's chained, it's important you time the fourth turret correctly. Use it when you see the last adds' health dropping so the tanks can finish them off while dps focuses on Razorscale.

Once Razorscale is down to 50% health, she will stop taking off and remain grounded. Now you won't have to deal with adds anymore and can focus on taking down Razorscale.

She will still use her Devouring Flame (blue flames) attack, so once you (the MT) see her casting the spell, you can already start moving. The flames will appear at the place you stood at when she started casting. If you are quick, you won't take any damage from them at all.

Also she will use Fuse Armor on the MT that will make him take more damage the more stacks he gains. As Razorscale is tauntable, the MTs will switch once on of them reaches 2 stacks of the Fuse Armor debuff. The debuff only stays for 20 seconds, so you should be able to taunt Razorscale back once the other MT gained 2 stacks.

This will be repeated until she's dead.

Normal Difficulty

You only need to use 2 turrets to get her down.
