Old Teach is the common name given to an invasive species of cactaceae found on several planets in the Vodyanoi system. The plant is known to thrive in wildly varying environmental conditions, but Xynobis and the mineral core of Gung have the highest known concentrations. Xorn scientists on Gung have attempted to eradicate the plant with little success.
Xynobyssian ape sorcerers believe the plant to be a sentient, psionic hive intelligence that amplifies magical abilities when consumed. Individual cactus colonies are said to remain in contact regardless of the distance separating them.
Any character who consumes the plant must save vs. Poison. Failure induces fever, vomiting, and paralyzing stomach cramps for d6 hours. A non-psionic character who succeeds will experience hallucinations and an expanded sense of consciousness for d6 hours. However, any psionic character will have all psionic effects (duration, range, strength, etc) doubled for the next 2d6 hours. If a point system is used to track psionic effects, the number of points available is also doubled for the duration of the effect.
