Antivenom

Cave spiders and witches are often a major nuisance when encountered due to the poison they use against the players. A bottle of antivenom could act as a solution to this problem. Drinking antivenom will give you a status effect of the same name for three minutes. For as long as the status effect is active, any poison status effects you receive will not damage you, only beginning to do so once the antivenom status effect ends. Unlike potions, antivenom is not something that can be crafted, but may instead be found in dungeons, stronghold hallway chests, or as a drop from Witches that become poisoned, as they will attempt to drink antivenom to halt the damage they would take from the poison. If killed while attempting to drink the antivenom before they are finished, they will drop this antivenom on death.
