Chaotic Life Passage

The caster drags a shard of glass across his/her arm while pointing at a target in sight within range. An attack roll is made against the target. On a hit, the caster's glass wound is healed, and the target takes 1d4 necrotic damage as its life essence is drained from its soul. The caster can then point to another target within range and deliver this essence to heal the target by an equivalent amount. If there is no other target within range, the life essence is released into the aether. On a miss, the wound inflicted during the casting of this spell is not healed and inflicts 1d4 necrotic damage halved.
