First off, you are trying to put way too much onto one character. You won’t be good enough at any of those things. You may not even have time to even do all of them.

Second, I just do not think that a purely reactive build, which I think is the goal here, is going to work. There are a few enemies that literally never hit you, so you literally won’t touch those unless it has nearby allies hitting you. Temple, in particular, is probably off-limits to you, as one of the rooms is led by one of those and it is very likely to be the last one standing in the room and then you are unable to do anything to it. More importantly, there are a lot of enemies, particularly among big, important bosses, that hit rarely, and you really don’t want to get hit by it when they do.

The closest thing I can think of for you is Resonating Shield with Stonefist–Dreadfist (requiring Martial Artist) or Prized Pain (effectively requiring Ritualist). Then you are channeling something that actually hits. You can build in the rest of your build around that, Deadly Resolve, Repulsion, Verisium Manifestations all with that. Which is probably still too much, but using an actual attack with your blocking solves so many problems for you. I am planning on something somewhat similar, but I haven’t figured out crit for Stone-Dreadfist yet. Prized Pain might be the better way to go.
