| Arachnid Quarter | Plague Quarter | Military Quarter | Construct Quarter | Frostwyrm Lair |
A wing of toxic slime filled with abominations and their creators. Four bosses. Previously known as the Abomination wing in level 60 Naxxramas. This quarter has slightly higher gear and coordination requirements than the first three wings and it is reccomended new groups tackle this quarter last. Patchwerk is a considerable healer test on Heroic difficulty and Thaddius is a considerable DPS check on Heroic difficulty. The trash clear to Patchwerk is long but Grobbulus and Thaddius have short clears. Gluth has no trash whatsoever.
