Many skills in the game have the effect of grabbing a target in some way (ie, Barbarian_Embowel, Barbarian_GiantSwing, Cataphract_Impale, Luchador_Martinete, etc), which prevents them from taking any action for some time. This can already be accomplished with the locking system, but it seems like this state has some special properties, most notably that targets that are grabbed should probably be immune to being targeted by most skills, except the skill they were grabbed by. DoTs and other effects should continue to work, though.
