Belladonna

When this bitter herb is consumed the player may re-attempt a failed saving throw vs. poison. It can only be used one time per person per room.

Note: Only one poison saving throw re-roll is allowed per person per room. E.g., if a poisoned character possesses both Anti-toxin and Belladonna, only one–not both–of those items could be used by that character to re-roll the poison saving throw.
