http://www.wowcataclysm-wiki.com/dungeons/blackwing-descent/chimaeronWritten GuideFinkle's Mixture - A buff that prevents you from dying to damage, as long as you are above 10,000 health. This buff is provided by the Bile-O-Tron
Break - Debuff that will stack on the tank. Will cause the tank to take 25% more physical damage. So once a tank reaches 3 or so stacks, make sure the other tank taunts the boss.
Double Strike - When Chimaeron gains this buff, his next melee strike will hit twice. So expect the tank's health to dip low whenever this happens.
Caustic Slime - Does around 150,000 damage and causes splash damage, so raid members should spread out. Will also debuff you with Caustic Slime, causing 75% hit reduction for a few seconds.
Massacre - Hits everyone in the raid with high damage. This ability will bring everyone with Finkle's Mixture to 1 health.
Feud - Everyone must stack on the tank when he begins to channel Feud. The Bile-O-Tron will go offline, so you will no longer have Finkle's Mixture, meaning you are at risk of dying when above 10,000 health now. Once Feud is over, Bile-O-Tron will come back online, so everyone can spread out again.
Mortality - When Chimaeron reaches 20% health, he will enter his burn phase. He will debuff everyone with Morality causing healing to be reduced by 99%, making all healing useless. This is when cooldowns such as Heroism should be used. While in his burn phase, Chimaeron will only use Double Strike.
Things to remember: Spread out, keep everyone above 10,000 health, tanks taunt off each other when
break stacks 3 or so times
Will be updated.
