Before Combat The blood thralls leap out of their barrels and attack the PCs.
During Combat The blood thralls relentlessly pummel opponents to death, feasting on their remains for 1 round before re-engaging in combat.
Morale Blood thralls have some sentience but very little, and these creatures have been commanded to fight to the death (which they do with great zeal).
