I've been hitting my head up against the Boss-Cell-1 Hand of the King for way too long now. I've already maxed out two levels of the legendary forge and the third is locked, so I don't even have anything to spend cells on anymore. it's like the game is telling me, "You should've beaten this already."
no matter how strong of a build I'm workin' with, I almost always get totally steamrolled by HOTK. even when I don't, I merely survive a bit longer, but I don't do significantly more damage.
another frustrating factor is that sometimes single hits from bosses will eliminate nearly my entire health bar. and that's *without* weapons that have "100% damage taken" attributes. I just don't understand it. the game is super addictive, but it's time for something else for a while.
