Unicorn Skull

Its a real thing. National Geographic and everything!

Complete unicorn skulls are rare. Most are hacked apart for their horns and by some mystical process skull without its horn becomes magically inert, though still highly useful in the intimation of movie executives (+5 to all relevant rolls).

A skull with the horn still attached however, has many uses: paperweight, conversation piece, a really cool hat rat, but it can also be used in summoning ceremonies and for crafting the virgin-finders used by the bigger asshole class of priest, some sacrificial cults and fraternities.
