In the File "Poisons.cs" you must change: Code: case NonLethalPoisonType.Leeching: if (SpellManager.HasSpell(LeechingPoison) && !StyxWoW.Me.HasAura(LeechingPoison)) return MindNumbingPoison;;; break; to Code: case NonLethalPoisonType.Leeching: if (SpellManager.HasSpell(LeechingPoison) && !StyxWoW.Me.HasAura(LeechingPoison)) return LeechingPoison; break; then it works ^^
