Serpent's Fang Dagger

Weapon (Dagger), Uncommon
The Serpent's Fang Dagger is a finely crafted weapon with a serpent-like motif along the blade. It is imbued with a potent venom that enhances its effectiveness in combat.
Poisonous Strike: On a successful hit, the target must make a Constitution saving throw (DC 12) or take an additional 1d4 poison damage. Additionally, on a failed save, the target becomes poisoned for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the poison effect on a success.
