Health buffer

Requirements:
* Health buffer is depleted first, always. No exceptions. – Meaning armor, shield, or such penetration does not invalidate it if such exist.
* Nothing can negate this buffer as if it was a special effect. – Meaning if it's energy shield, EMP or such won't disable it entirely unless the damage would otherwise overcome it.
^ Bonus damage against the health buffer however is acceptable, as long as it isn't on level of entirely disabling it simply by overcoming any and all shields with massive bonuses.
