Vondok's Fang

You gain a +1 bonus to Attack and Damage
Rolls made with this Magic Weapon.
You can use an action to cause thick, black
poison to coat the blade. The poison remains
for 1 minute or until an Attack using this
weapon hits a creature. That creature must
succeed on a DC 15 Constitution saving throw
or take 2d10 poison damage and become
Poisoned for 1 minute. The Dagger can't be
used this way again until the next dawn.
