Poison

Very Rare (Injury)

Applied to a melee weapon or up to 5 pieces of ammunition. A creature subjected to this poison must make a Constitution saving throw with a DC equal to the crafter's Poison DC, taking 6d6 poison damage on a failed save, or half as much damage on a successful save.
Once applied, the poison retains potency for 1 minute before drying, and wears off of a weapon after that weapon has delivered the effect 5 times.
