When a Loyalist is trained enough in the occult, they can rank up into a Priest. Priests are even more durable than Loyalists, but they gain two important capabilities: The ability to heal injured allies in combat, and the ability to start recruiting Loyalists themselves.
The Priests go as follows:
-Silverfish Priest
-Cave Spider Priest
-Spider Priest
-Skeleton Priest
-Zombie Priest
-Creeper Priest
-Zombie Pigman Priest
-Blaze Priest
-Wither Skeleton Priest
-Ghast Priest
-Enderman Tseirp
