|Just Can't Get Enough (10 player)||10|
|Defeat in Naxxramas while killing at least 18 abominations in his chamber in 10 player mode.|
The key to this is that in the normal course of the encounter, some of the abominations waiting in the wings will not come out and attack on their own. Send someone to pull a few extras, but beware the banshees!
This achievement is likely named after the Depeche Mode song, "Just Can't Get Enough".
