Poison

From DDO wiki

When you are exposed to poison, you are required to make a saving throw vs. the poison's difficulty class. Your character will have a modifier to this saving throw that is derived from your class levels, and your race- and is potentially modified by what enhancements and feats you have taken, as well as whatever buffs have been cast on you, and what equipment you are wearing.
