This trait can only be selected by Orc characters.
If you have a whip you can use the whip against an ally within the melee range of the whip, and so long as they ally is willing they can suffer 1 point of nonlethal damage which bypasses their armor, and receive a +2 bonus to all checks they make (attack rolls, skill checks, and so on) until the beginning of your next turn. This can only affect a single person at a time, and the same person cannot benefit from multiple Orcs whipping them (although, don't tell the Orcs that - they may just do it anyways).
