This command toggles your character between normal combat and sparring mode. In sparring mode, you will automatically stop combat before inflicting any real damage to your opponent - preventing you from killing them accidentally.
Note: While sparring will not kill or maim your opponent, it may still injure them or cause them to bleed.
Note: All parties involved in the fight must be in sparring mode for a spar to be in effect. If one party isn't, combat proceeds as normal and may end in death or dismemberment.
