Small wood and paper cocktail umbrellas that you might find in any Chinese or Polynesian lounge. If a Dipsomancer drinks from a vessel containing an opened Umbrella, he will be unable to gain charges from the drink (he will still suffer the effects of the beverage though). Once opened, the Umbrella cannot be used again.

If a Yin Umbrella is used on a vessel containing a spirit (ala Ghost Vintage), the opened Umbrella will "suck up" the spirit and trap it inside. The umbrella must then be closed quickly or else the spirit may escape (Speed check to see if the spirit can get away before the umbrella is closed). If successfully trapped, the Umbrella can be used to transfer the spirit inside to another vessel.
