Poison

Poison is a negative effect that causes the character or other beings to lose Hit Points over time. Being poisoned is not permanent and will eventually clear on its own, however this can take some time and in most cases, without any healing the character will die before it happens.

Cures
Poison can be cured by a Priest, drinking a potion of detox, or casting the Detox spell. While priests can immediately remove all poison, if the Detox potion is of a lower tier, or the Detox spell is cast at a lower level, they may not cure the character completely and need to be used additional times. Less common means of poison removal include the Sparkling Divinity potion (Book II).

Resistance
The character's Toxin Resistance represents the chance that they will avoid being poisoned when exposed to a poison source. This resistance is augmented by the character's Strength and Endurance attributes, as well as the Medicine skill. It can also be temporarily boosted by equipping certain items, including the Bitter Naga Amulet in Book I, the Lifeforce Pendant in Book II, the Band of Purity in Book III, and pieces of armor with the "Impervious", "of Purity" and "of the Immaculate" modifications in Book II and Book III.
