Damage Immunity

Damage Immunity is a buff in Xenoblade Chronicles. It provides a pool of temporary HP that must be depleted before the user can lose any of their own HP.

Temporary HP:
 * Takes precedence over HP no matter what the source of the damage is, be it a direct attack (of any type), a debuff, a spike, or even self-damage.
 * Does not factor into "current HP", so mechanics such as "lose 20% of current HP" do not count it. This includes the amount of damage caused by the debuff, allowing survival.
 * Does not block excess damage when depleted. Having 200 temporary HP means that 500 damage will take out all of it and deal the remaining 300 damage to the "real" HP.
 * Does not protect against status or debuffs.
