When a melee weapon coated in the poison damages an adversary they take and additional 1d8 physical damage and must make a difficulty 13 roll or become poisoned and have disadvantage on action rolls until the condition is cleared. The poison stays on the melee weapon until the end of the scene or until the first successful hit whichever comes first. If collected from a pain beast's poison sacs there is enough for 3 applications to a melee weapon.
