Blood Minister Syringe

Wondrous item, uncommon
  Made of silver and glass, this peculiar apparatus magically refills with blood each dawn. A small dial around the plunger depicts carved images of beasts. Rotating the dial to each of these beasts changes the hue of the blood: bear, an iridescent black; bull, a sanguine red; cat, a silky purple; eagle, a piercing yellow; fox, an opulent orange; and owl, a midnight blue. Legend says blood from the sacred animal spirits of each of these races was extracted in the crafting of this macabre, performance-enhancing syringe.
  As an action, you can select a beast and inject this blood into a willing creature, casting the spell enhance ability on it. The spell does not require concentration when cast in this way.
