Castle Nathria: Getting a Head

Castle Nathria: Getting a Head is the usual raid shortcut quest. Defeat Sludgefist four times in the same difficulty to unlock a shortcut to Sludgefist again in future resets. There are three versions of this quest, one for each non-Raid Finder difficulty, and they all track progress separately. However, should players skip ahead and kill four times on Mythic, they will unlock the shortcuts on Normal and Heroic.

Objectives
