Potion, very rare
When this poison is ingested by any living creature (excludes undead or constructs) the creature must succeed a Constitution save against DC 20, or take damage equal to their current health, rounding down, at the beginning of each round for 1 minute (the minimum damage taken can be equal to 0). After 1 minute, the creature takes damage equal to its Constitution ability score.
If any effect to cure, diminish the effects of, or help fight against poison other than the antidote (Boon of Immunity) is applied to this creature while it is poisoned this way, the effect only has a 20 percent chance of working.
Notes: Damage, Consumable
