Hi, there is an antidote, which is sold in all item stores and occasionally appears as loot.
In Rako (the first town) it is on the second floor of the Trade Office building.
In Gyon it is to the left of Shura's apartment, in the center of the city.
In Kimura it is practically in the center of the town.
As a help the item stores have this sign:
I thought about including some neon signs to make it more visible to the players lol
