Description: Festergut's heroic mode is very simple, he only gains one new ability - Malleable Goo. That's the same Malleable Goo from the Professor Putricide encounter! The key to avoid being hit by goo is to angle your camera up towards Professor Putricide, you will see him cast one at a time and it will go straight for the person it's targeted at. Festergut will also hit much harder, encouring you to start using tank cooldowns at 2 stacks of Inhaled Blight. Pungent Blight is also a guaranteed death for anyone with less than 3 stacks of Inoculated. We found Festergut to be one of the easier heroic encounters in Icecrown Citadel.
