Bloodstones

Bloodstones are magical jewels that possess basic spellcasting capabilities, as well as major healing abilities. Only trade with Duergar miners can allow someone to obtain them (or trade with someone who has already done so). They allow for simple transmutation, the casting of light at will, and the storing and expelling of life force energy (hit points). Depending on the size and cut of a stone, it can store a certain amount of HP. These hitpoints can then be spent to heal or harm others for an amount of damage equal to the number of stored HP you spend. You do not have to roll against AC to attack with a bloodstone, but it MUST come into direct contact with the target. The attack is an explosion of energy originating from the stone, directed away from the wielder. If more than 10 HP is spent on the attack, it knocks the foe prone.

Someone can only use a bloodstone they are bonded to. The bonding ritual involves someone voluntarily cutting the palm of their hand and holding the stone in the bleeding hand until the stone heals it automatically.
