How viable is an Eldritch Guardian Martial Master Fighter with a King Crab Mauler Familiar?
I was thinking of all the Grapple Feats plus Coordinated Maneuvers.
Later on, once I have Anaconda’s Coils, I could add the Final Embrace Feat line.
Technically, since I have UMD as a class skill, I can get a lvl 2 or 3 wand of enlarge person and make the Crab and me size large.
I'm just not sure, how good a grapple build outside of Brawler and Tetori really is.
Grapple is a very solid combat maneuver, but I don't know if I would bother with things like Final Embrace; once you have them grappled you are only a couple of actions from making them helpless anyway so the damage doesn't mean that much IMO. It's also nice for you that as a Fighter you have plenty of feats for grapple while still having enough to have other combat options.
If I were you I would consider going with a weasel instead of a king crab familiar; weasel auto grapples on a hit via attach, no action, no CMB check. Against some enemies CMD can be a lot higher than AC, so that could be handy in a pinch. Alternatively a monkey, or anything with hands really, would be nice as they could actually tie up enemies in a grapple.
Sorry but can't give more in depth thoughts on a build at the moment.
