Murk Blowgun (Patreon)

Weapon (blowgun), uncommon

A hefty blowgun used by the inhabitants of the Murk: a series of deadly swamps whose waters are polluted with an uncanny poison. When you hit a creature with a ranged attack using this magic blowgun, that creature takes an extra 1d4 poison damage. When you roll a 20 on a ranged attack roll made with the blowgun, the target must also succeed on a DC 13 Constitution saving throw or be poisoned until the end of its next turn. It is incapacitated while poisoned in this way.

In addition, this blowgun can be wielded as a magic club.

From the gurgling, tar-like muck of the swamp, they could hear the sound of bubbles reaching the surface and burping. The air stank, and though they were tired from the struggle against the muddy depths, taking deep breaths only made them gag and surrender more from their lungs.

Amidst the warbling and organic 'blurps' and 'pops' from the swamp's bubbles, a chorus of similar, but far more serious sounds emerged.

Pfwup! Pfwut! Pffwup!

One by one, the weary travelers collapsed: face-first into the welcoming embrace of the Murk.
