Edit: I want to make it clear that this is not a finalized PoB. Things like the CWDT breakpoints, flasks, and resistances were things that I intended to polish when I had a character in-game to test with, but I never ended up making that character. Resistances can be filled in on gear where undesirable/open affixes end up, considering I doubt anyone will actually make the PoB gear 1:1. Flagellant flasks were an idea that I ended up disproving (for this build), but I had bigger issues to fix at the time. I have almost no experience in building, so I'd like to think that many of the build's issues could be fixed up by someone more experienced, if they wanted to do so.

I haven't seen a build quite like this yet, so I thought I'd post it in case anyone's interested (or to be told it was tried and failed already). I had hoped to try it myself, but I just don't have the currency or time (I'm not even sure I have time to get my last 12 challenges). This was originally conceived as a bossing setup for a few reasons, but I think it could be adapted to mapping easily, maybe with just a weapon swap or gem swaps.

There are 2 independent ideas here:

Strength stacking: Get a bunch of Str and scale it with Iron Will and Shaper's Touch. Str now gives flat life, flat mana, % energy shield, and % spell damage. Iron Will getting on the tree was a blessing for this.

Cast When Damage Taken: Trigger CWDT by spamming either Forbidden Rite (plus Cast While Cycloning?) or Boneshatter (what I originally decided on, hence the bossing focus). Use life and mana recoup to manage the self-damage as well as recover mana quickly for further high-mana casts. Boneshatter is easier to manage the damage (especially as a Jugg), but is melee and needs Trauma stacks. Forbidden Rite wouldn't have to ramp up at all and doesn't need a target, but will need you to manage your chaos res (which has the benefit of you having chaos res).

I know some of the gear in the PoB is a little over the top, but I was trying to get an idea of the build's ceiling to decide if it was worth trying. I never really finished fine-tuning it, but I'm also not an experienced build maker, so I expect that there's a ton of room for improvement (which also makes me hopeful that it has real potential, mostly the strength stacking). I also know the CWDT archmage isn't entirely novel, but I wanted to work it in originally and I don't have time to pull it out of the PoB.
