Trading Post:Potions   Poison (250gp): This potion isn't imbibed. It takes a full round to coat a weapon with this potion. A weapon will remain coated with this potion until it strikes, if a melee weapon, or is fired, if a missile weapon. If the weapon does not successfully hit, or is not fired, in 3 rounds, the coating fades. On a successful strike the opponent receives a saving throw. If the saving throw passes, the opponent takes only the d6 initial damage. If failed, the opponent will take d6 damage, then d6 damage at the end of the round for d3+3 rounds (counting the initial damage). This further damage cannot disrupt spells.
