Terasology has an AlterationEffects module that implements a basic set of status effects (buffs and debuffs) that can alter a player's base state in some fashion. These include health regeneration, mobility increases, damage reduction, poison status, etc.

Your task is to add a decover effect to this module. What this effect does is prevent any healing from working on the target entity. This includes healing from items and other effects.

Hint: Cancel or consume the BeforeHealEvent to cancel out healing entirely.
