Breastplate of Fungal Spores

While wearing this armor, you can take a bonus action to make the armor emit poisonous spores, which fill a 10-foot-radius sphere centered on yourself. Each creature in that area must succeed on a DC 15 Constitution saving throw or have the poisoned condition until the end of your next turn. Once this property is used, it can't be used again until the next dawn.

This armor consists of a fitted metal chest piece worn with supple leather. Although it leaves the legs and arms relatively unprotected, this armor provides good protection for the wearer's vital organs while leaving the wearer relatively unencumbered.
