Plasma Shield

This is the Protoss form of Healing. A portion of their health is called Shields, and regenerates slowly when not in combat.

Overview
Plasma Shield points act as another form of HP and are usually lost first. Shield points regenerate slowly but a Shield Battery or Sentry may be used to restore them faster. Shields take the same bonus damage as the unit they are protecting. Shields caught within an EMP are reduced to 0 points. Plague bypasses shields entirely, leaving them untouched and attacking the HP of the unit underneath. Shields in KoL are more powerful than in vanilla SC2, because they start at the Armor level corresponding to the Unit Tag, instead of always zero.
