Foul Warding Grenade [CARD] (Patreon)

Wondrous item, uncommon

A simple explosive device concocted to combat the unholy scourge. As an action, you can throw this grenade at a point up to 60 feet away. The grenade opens, spewing a cloud of garlicky stench that lingers for up to 1 minute or until a wind of moderate or greater speed disperses it. Each creature within 10 feet of the grenade must succeed on a DC 15 Constitution saving throw, taking 2d6 poison damage on a failed save or half as much on a success. When a creature enters the grenade’s area for the first time on a turn or starts its turn there, it must succeed on a DC 15 Constitution saving throw or take 2d6 poison damage. Fiends, undead, and transformed humanoids have disadvantage on these saving throws and lose any resistance or immunity to poison damage while within the cloud.

A mix of herbs and substances that many of the infernal find unbearable is packed into each of these tiny contraptions. Upon releasing its foul contents, a single grenade can render an area inhospitable to all nearby creatures as the stench of garlic begins to waft about the battlefield.
