Dark Souls II

If you have an unpatched version of the game, this glitch still works. The engraved gauntlets give a chance for a normal hit to do the damage of a critical hit, like a backstab or riposte. Keep attacking until you trigger a critical hit from the gauntlets, then take off the gauntlets. Every hit will now become a critical, for a lot of damage. Will only work on PvE because you cannot play online without patching your game.

There's a coffin in Things Betwix in the sand circle where the fat big guy stand. If you enter in that coffin your character will swap its gender with the major facial details.
