Description: The heroic version of Professor Putricide has quite a few changes that make the fight a lot more interesting. First off, Putricide will no longers stun the whole raid during transition phases, instead he will spawn a Gas Cloud AND a Volatile Ooze. Every member of the raid will recieve one of two debuffs - Ooze Variable and Gas Variable. Raid members with the Ooze Variable may only attack the Volatile Ooze, those with the Gas Variable may only attack Gas Clouds. A new ability called Unbound Plague will also go out on the raid during all 3 phases (but not during transition phases). Unbound Plague deals damage based on how long it remains on its target, it must be passed on by moving within 3 yards of another player. Once Unbound Plague has been passed to a new host, the previous host gains a debuff called Plague Sickness, which increases the damage taken by Unbound Plague. The approach to Phase 3 is also somewhat different, instead of spreading Mutated Plague among 3 tanks, you'll want to use at least 4 to gain the additional DPS time needed. We opted to use a DPS feral druid to tank for 2 stacks with damage reduction cooldowns.
