Slayth Fang

This Fang is a Magic Weapon. When you hurl it and speak its Command Word, it transforms into a blast of poison, forming a line 5 feet wide that extends out from you to a target within 120 feet. Each creature in the line excluding you and the target must make a DC 13 Dexterity saving throw, taking 4d6 poison damage on a failed save, and half as much damage on a successful one. The poison Bolt turns back into a Javelin when it reaches the target. Make a ranged weapon Attack against the target. On a hit, the target takes damage from the Javelin plus 4d6 poison damage.

This item can be used once.

First appearance
This item was scavenged from the corpse of a Slayth, a large and alabaster snake/crocodile-like monstrosity with humanoid teeth. Himo Longbeard ripped the fang out of the mouth of the huge Slayth after slaying it. Though Slayths usually have more fangs, not all of them have magic properties and the other fangs were destroyed during the combat.
