I sadly don't remember the name of the game any more, but it was an open world rpg around the time of Oblivion and Gothic 3.
It had an alchemy system to create potions and, depending on your skills, it was possible to get a debuff effect instead of a buff. You could also use a potion as an ingredient for a new one, compounding the effects. The exploit was a pretty basic variable underflow: keep combining bad potions and you would get worse and worse results, until at some point the sign on the effect would flip from a number in the negative millions to a positive, giving you a massive boost to whatever stat you had selected for the potion.
