Whenever you are hit by an attack that would damage you, you take that damage as a limb hack instead. All damage types still apply. If the hit was critical, you instead take it as two limb hacks. If you attempted to block the triggering attack, then a limb that used whatever item you blocked with is the one that's hacked. Otherwise, if the damage was dealt by a creature, they choose which limb is affected. If not, it is random. Only an un-hacked limb can be used for this. If that's not possible, you take the damage normally.
