Limb Chopper

The Limb Chopper weapon effect can seriously reduce the movement and attack speed of the victim. On an attack roll of a natural 20 which is also confirmed as a critical hit, the target suffers a permanent penalty of -75% movement and attack rate. There is no particular animation or effect for this debuff. It is permanent until the victim rests, or dies. (Note that the in-game description on the weapon states that the attack penalty is only 50%, which is an error)

The following creatures are immune to Limbchopper (often because they do not have limbs, or do not need particular limbs) Undeads (except vampires) Constructs (except warforged) Red-named bosses Beholders Oozes It is possible that the Deathblock and Deathward effects prevent Limbchopper.
