Spiderbite Daggers

Spiderbite Daggers
Weapon (dagger), rare

These daggers are made using the harvested fangs of a large venomous spider. When you hit the same target on your turn with each dagger, that target must succeed on a DC 14 Constitution saving throw or take an extra 2d4 poison damage and become poisoned until the end of its next turn.

The venom the spiders carried was agonizing: like daggers racing within our veins. How fitting then, to materialize the fangs of the fallen creature in a way such as this.
