Priest

A support unit who lacks a direct means of inflicting damage, but summons mummies at a rapid rate.

Properties
Mummies appear wherever the Priest's magic orb has traveled a certain distance. If the orb hits a wall before reaching this distance, it disappears without spawning a mummy. However, if the ball touches the Warlock, it passes through and spawns a mummy behind him.

Strategy
The Priest is easy to miss in the midst of battle, save for a sense that all those mummies have to be coming from somewhere. The Crossbow family is the most effective tool to get rid of him and his minions.
