Dread Plague Antidotes are Medicine Items added by Abyssalcraft.
The player can use their 2x2 crafting inventory to throw together a Water Bottle, Dread Fragment, Dreadlands Wood Sapling, and Dreaded Shoggoth Flesh to create this antidote containing 10 doses.
Regardless of whether or not the player is infected with the Dread Plague, the player can ingest this item, reducing the dose counter by 1. Ingestion of the antidote cures the Dread Plague, no matter how intense or durable it is. After the 10th dose, it will be an Empty Bottle.
