There is a potion you drink to cure deseise, im not sure what its called, but you drink it, and you need to roll a heal check... i dont see the point in the roll, are you too stupid to put a potion into your mouth? :lol:

I think the potion's purpose is to represent balms, lotions and such used to remove any remains of disease from a wound and the system. The roll represents this. Else it would just be potion "cast spell: remove disease (5)". I think the potoin was added to prevent heal kits from bieng "one use heal all".

Fish basically has it. I may rename it and change the appearance at some point, since the "potion" appearance could cause confusion -- but this is the intended behavior at present.

Think of it as a bottle of medicine. You need enough skill to determine a proper dosage if you want to actually cure the posion/disease.
