Purger

Purgers are powerful kamikaze units that emit a cloud of deadly Lysozyme, dealing very heavy dissolve damage to all nearby units, including itself and allies, essentially sacrificing themselves for the good of the colony.

Lysozyme Secretion:
When this ability is cast the Purger will begin to emit a cloud of lysozyme from itself dealing lots of dissolve damage to anything nearby including allied units. As long as the Purger is alive the AOE of the lysozyme will continue to expand. Once the purger dies it will no longer emit and Lysozyme and the remaining lysozyme will begin to dissipate and after a length of time disappear. Once cast the Purger can no longer move or take any other action.
