It doesn’t matter whether you party with a sorcerer who’s got a black tentacles fetish, need to restrain your mind controlled barbarian, or happen upon a owlbear wrestling exhibition with a big cash purse on the line. At some point, somebody at your table is going to need to understand how the grappling rules work. It’s all well and good to read through the combat chapters and download the flow charts, but if you want to preserve your brain cells you’re going to want a rules lawyer. I mean seriously. Look at those flow charts! No sane human being is going to try and fit that all within their heads, which is why you’ll want your own plucky idiot savant to take up the slack. I suggest acquiring a classic fat beard, but a quivering man jelly or the common basement dweller will also work in a pinch.
