Antitoxin Serum

This injector holds a bluish, bubbly liquid. A creature can administer it to themselves as a bonus action, or to another creature as an action. If the target is poisoned, you neutralize the poison. If more than one poison afflicts the target, you neutralize one at random. For one hour, the target has advantage on saving throws against being poisoned.

Notes: Advantage: Saving Throws
