His lack of offensive power reminds me of this one terrible character build I made in Neverwinter Nights back in like 2000-2003 or so. It was some sort of bard/cleric/monk that could raise its AC to a ridiculous fucking amount. But he could not hit something to save his life, so he needed to roll crits to do that... at which point the damage rolls would still be bad so it'd take forever to kill anything and they would absolutely have to not be able to even slightly regain health at all. It was fun to duel people online with it though, they'd get frustrated and give up.
