It's your call. I personally wouldn't rule it that way if that matters.<br/><br/>My original intention with this mechanic was to use the multiple (2-3) grapple actions per round for the monsters, but if you don't want that I guess you could say something like, if they use rend armor on a grappled or pinned foe, they ignore hardness in addition to the 2x melee damage going for the armor.<br/><br/>Or if that still takes too long, we can make the process a simple grapple maneuver? On a success the armor is removed.<br/>Or a "save or strip" effect, basically the wearer of the armor making a saving throw to avoid getting stripped?
