Blood-Ablution

Drench yourself in the blood of a recently slain creature and fan some of the strength of its blood. Caster gains a buff relevant to the creature slain. For example, a rabbit may confer additional movement speed, a turtle additional AC, or even a troll may confer its health regeneration. Amount, strength, and type of buff(s) conferred is at DM discretion, but should scale roughly with the challenge rating of the slain creature. Slain creature must have blood and be able to bleed. Must be cast as a ritual.
