Badge of Sacrifice

A small, shield-shaped silver emblem that can be affixed to the chestpiece of one's armor, or to a cloak to fasten it in place. Once used by the traveling order of knight-priests known as the Penitent Ones, a subsect of the Church of the Silver Flame, this badge represents a warrior's determination to care for others, even at the cost of their own well-being. It is emblazoned with an intricately-crafted heart design, and seems to be permanently bloodstained -- no matter how much you try to clean it, at least a few droplets of blood will remain.

If your Lay on Hands pool is empty, you may expend your own hit points to heal a creature as though they were in your Lay on Hands pool. When you do so, your hit point maximum is reduced by an equivalent amount and cannot be restored until you finish a long rest, but you awaken from your long rest with temporary hit points equal to your Paladin level + the number of hit points you sacrificed the previous day.
