Nightshade

Nightshade

Not to be confused with the rank-smelling plant of the same name, the fungal cap from this rare and unusual mushroom may be either crushed or boiled into a tea. The mage must always use great care when handling nightshade, for it is not only a very potent hallucinogenic, but also extremely noxious. It adds illusory or poisonous elements to a spell.

Nightshade could only be found in Ultima IV in the depths of Spiritwood or near the Shrine of Sacrifice, but could be bought in later games at expensive prices. In Ultima IX, it appeared as a leafy plant rather than its historically fungal portrayal.
