Ulduar 25 Guide - Razorscale

Razorscale is a large, pretty drake that flies high above Ulduar and, contrary to what most of my guild members seem to think, Razorscale is a GIRL! Your encounter with Razorscale will consist of 2 phases: an aerial phase, and a phase in which she is permanently grounded. This guide focuses on a restoration druid's job during the encounter.

Phase 1
During phase one, your raid will spread out around the large circle on the ground, being sure to keep a safe distance between yourself and your raid members. Throughout this phase, adds will spawn from the mole machines that drill up from under ground. Three types of adds spawn, and this is the order in which they must be killed:

Sentinels
Sentinels are dangerous to melee, as they Whirlwind for around 9,000 damage on plate wearers. It's important that these mobs go down first.





Watchers
Watchers are very dangerous to your raid as they cast a Chain Lightning that does more damage with each person it jumps to (hence why it is very important to keep a good amount of distance between yourself and your raid members). These mobs can be CC'd using sheep, fear, stuns, etc.


Guardians
Guardians are the last on the kill priority list. They have a Stormstrike ability that increases Nature damage done to the target by 20% for 12 seconds. I'm pretty sure this is what they look like - I don't pay much attention to adds!



Throughout this phase (and phase 2) large Fire Balls will periodically fall down from the sky and hit a raid member, dealing about 14,000 damage. If you periodically use Rejuvenation on your raid members, a quick Swiftmend or Nourish will heal them back up to full. While you're busy killing adds and avoiding Razorscale's Devouring Flame (giant cloud of blue fire on the ground that inflicts 7,000 to 9,000 damage every second), your friendly dwarf allies will be busy putting those turrets back together, pictured below.

One of your raid members (probably a hunter or a mage) will activate the turrets as they are built and once the last one is activated Razorscale will be grounded for approximately 40 seconds.

In this portion of phase 1 there isn't a great deal of damage happening to the raid, so feel free to release your inner Critturkey, Lazer Chicken, Doomkin, Boomkin (etc.) and do some damage. After ~ 40 seconds Razorscale will get pissed off and do a Wing Buffet, which will knock back everyone in her range (so be sure to stay away from her to avoid getting out of range to heal your raid). Phase 1 will repeat again until you get her to 50%, at which point Phase 2 begins.

Phase 2
In phase 2 there will be two tanks, one taunting off the other when the current tank has around 3 stacks of Fuse Armor, a debuff that reduces armor, attack and movement speed by 20% for 20 seconds and stacks up to 5 times. Make sure to roll full HoTs on the current tank, and keep HoTs on them even after Razorscale has been taunted off.

Just like in phase 1, Razorscale continues to barf up big clouds of blue fire; AVOID IT! Periodically you'll get more applications of Flame Buffet, a debuff that increases fire damage taken by 1,000 (stacks up to 99 times). This isn't very dangerous unless you:

1. Decide to bathe in big, blue clouds of fire
2. Decide to walk in front of Razorscale

Razorscale's Flame Breath ability has a rather large cone of attack, so just avoid her front at all costs. Rinse and repeat until she's dead, and hopefully Bracers of the Broodmother drop!

TL;DR Version

• Avoid Devouring Flame (large, blue clouds of fire on the ground)
  
• Use Rejuvenation + Swiftmend/Nourish to quickly heal up raid members hit by Fire Ball
• Keep a safe distance between yourself and your raid members to avoid getting hit by Chain Lightning
• Don't stand too close to Razorscale when she's temporarily grounded or risk getting knocked out of healing range by her Wing Buffet
• During phase 2, avoid Razorscale's front and continue to avoid Devouring Flame
• Keep full HoTs on both the Main Tank and the Off Tank during phase 2
