Edited the previous post.<br/><br/>My point is that mechanically they are much more versatile than any character, since they get multiple actions per round and can disable multiple characters. There is no real mechanic in place to let PCs hold up to that, except expensive magic, but even so the actions they take is limited.<br/>If you want to keep the multiple actions per round thing, I recommend taking a look at how d&d 4e handles solo monsters, or just have several monsters that each grapple individually.<br/>Don't worry, we'll get this working yet.
