Mindshadow: This non-magical poison is brewed from a variety of arboreal fungus and is available in most temperate climes for between 300-1,800 gp per dose. When introduced into a human's bloodstream, mindshadow causes extreme disorientation and both visual and auditory hallucinations in the victim, who must make a saving throw vs. poison to resist the effect (onset time is only 1-3 rounds).

Victims failing their save become confused (as per the wizard spell) for 5-20 turns. During that time, the victim is highly susceptible to suggestion (-6 penalty to the saving throw to refuse a specific request) by anyone conversing with or questioning the victim. Mindshadow can be used in combat to disorient opponents, but it is much more often employed by necromancers during the interrogation of prisoners. Since it leaves the victim almost totally at the mercy of frightening hallucinations and suggestions, mindshadow is rarely used as a recreational drug.

Mindshadow only works effectively with humans. Other races and monsters gain a +1 to +4 bonus to their save (onset time 2-12 rounds, depending on their physical size and the amount of poison employed). If they fail, they arc only slowed (as the wizard spell) for 2-12 turns (with no susceptibility to suggestion, as in humans). Dwarves are immune to the poison's effects.
