Information

Razorscale is an Ironbound proto-drake that flies over the Razorscale's Aerie, across from the Colossal Forge. It seems Razorscale is the product of Loken's plans with Veranus judging by the names of several items that drop off of her.

She has two separate phases: on the air phase, you kill iron dwarves and on the ground phase you attack Razorscale. At 50% she lands permanently and needs to be tanked. The fight has a 10 minute enrage timer.

Strategy

10-Man

The fight proceeds exactly like the 25-man variant, except that only two turrets need to be repaired and fired instead of four.

25-Man

This boss fight consists of three phases, alternating air and ground phases until 50% damage taken, and then a pure ground phase from 50% to 0%.

Recommended Setup

  • 3 Tanks
  • 3 Tank Healers
  • 3 Raid Healers
  • 0-2 Floating Healers
  • 14-16 DPS (composition irrelevant)
   Talking to the Expedition Commander will begin the event with Razorscale in her air phase.

Razorscale appears to have two separate Beserk timers, the first applies during phase 1 and 2 when rotating the air / ground phases and occurs approximately 5 minutes into the fight, a second longer one is in operation if she is successfully moved into phase 3 before this. This places a limit of roughly 3 ground phases on the raid.

Air Phase

The air phase consists of defending the Expedition dwarves while they repair the harpoon turrets. During this phase, the focus should be on defeating adds (Sentinels are priority, Watchers must be CC'd and killed second, Guardians last), and staying out of Devouring Flame. As the turrets get repaired one at a time, they can be clicked to fire a harpoon at Razorscale.

The raid should be split into three groups, one near the far side of the circle opposite the harpoons, and two groups positioned slightly round the circle back towards the harpoons. Each group should engage the spawns from a single pod and destroy them, there is no need for crowd control and AoE can be used. If a sentinal spawns all 3 DPS groups should focus fire this target as it presents the greatest and only tank threat amongst the spawned adds.

Floating healers should be assigned behind the three groups to support heal and heal the players assigned to trigger the harpoons.

Harpoons 1-3 should be activated as soon as the third harpoon becomes available, with harpoon four being activated as soon as there is no sentinel present (the sustained damage from this add prevents additional healer and tank dps being focused on the boss). DPS should begin to converge into the circle when the third harpoon becomes available to minimise time lost in the ground phase.

During this phase it is important to ensure that the raid healers keep members of their party above 12,000 health as this prevents losing targets to a single breath, a double breath is possible (and common) so healing must be fast and effective (Paladins are ideal in this role due to Holy Shock). Healers first priority must be to keep themselves alive.

Ground Phase

Once all four turrets have been repaired and fired, Razorscale will be forced to the ground where she will remain stunned for several seconds. Everyone should immediately move behind her, and DPS should focus on bringing her HP down as much as possible while the tanks hold any remaining adds. After the stun wears off, Razorscale will breath then return to the air and begin the air phase again.

For this phase tanks should converge onto the rear of Razorscale allowing their DPS to be added to that available in this phase, with 5s remaining until the stun wears off the tanks should move with any remaining adds towards the furthest point on the circle and allow full raid AoE damage to be applied to the adds. As new pods appear tanks should move their adds back to their regular tanking positions.

Phase 3

Once Razorscale is brought to 50% health, she will land permanently, at which point she will need to be tanked facing away from the group to avoid breaths. The fight from this point is very simple, she will continue using Devouring Flame, she will do a knock back to everyone within 35 yards, and inflict the Flame Buffet debuff. During this ground phase, the DPS should go all out in order to defeat Razorscale before the Flame Buffet debuffs cause the tank to be one-shot.

There is another debuff that happens during this fight. In phase 2, when you are tanking Razorscale around your tanks will get a debuff called "Fused Armor" which adds a slowing effect to the tank. When this debuff hits 5 stacks the tank can't move or use any abilities, including taunt. You need to change tanks when the debuff gets to 2 stacks in order to finish the fight.

Note as of 4-15-09 on live you can no longer dps boss while it is in the air.
