Low HP set

The Low HP set is a group of equipment that benefits from having a small number of hit points and includes items that damage the wielder to more easily reach those low HP values. The self-burn from the Heat Set also helps lower HP. Note that  temporary hit points is not factored in to the activation conditions of these items.
