Mind-Numbing Poison

Item Level : 4

Item Type : Consumable (Poison)

Gold Cost : 750 GP

Weight : 0.5 LB

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.

On a failure, they become poisoned for 1 minute. While poisoned this way, If the creature attempts to cast a spell with a casting time of 1 action, roll a d6. On an 5 or higher, the spell doesn't take effect until the creature's next turn, and the creature must use its action on that turn to complete the spell. If it can't, the spell is wasted.

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.
