Player can gain a secondary health bar that is depleted before the actual health is ever touched, this can exist in form of temporary hitpoints, armor, shields, or pretty much anything but functions the same.
Alternate name: Temporary hitpoints
The first video game about Health buffer was released on February 15, 1995.
* 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.
