t3h old trick, but newbies will like this...
Actually, there is no reason to buy stuff like Antidotes and Eyedrops in this game; there is a very,
very cheap "glitch" that allows you to cure stats in a different way:
Relics.
Equipping the proper Relic will cancel any stats that Relic is intended to protect from, e.g. equipping the Star Pendant will cancel Poison, Goggles will cancel Blind and so on. :D
This is really handy trick, and it also means you wonŽt need to buy more than one of each Relic of this type. :D :D :D
Oh, and feel free to unequip them immediately afterwards. :)
