 * The game uses the term exploit to describe the act of using a corpse for certain necromancer spells. For more information see: Corpse Exploitation.
 * The term exploit is an unofficial term referring to players utilizing a bug/error in the game to benefit their characters. An exploit can be a weakness in a difficult mission or quest that allows players to finish it easily and gain the rewards without much hard work. It could also be an error in the game whereby players can become invulnerable to damage, or make lots of money by fiddling with the merchant window or any such similar hack.
