POISON
Syntax: cast poison <victim> Syntax: cast poison <object> This spell reduces the strength of the victim, as well as reducing the victim's regeneration rate. It may also be used to poison food, drink, or a weapon in a fashion similar to envenom ('help envenom'), but with drastically reduced effectiveness. In addition to reducing a targets' strength, Poison also applies a small skill penalty, similar to the one imposed when low on health.
