I am trying to build a character that can kill some of the uber bosses that my mappers struggle with, and was wondering if this is a good idea:

Take on a suicide bomber build using discharge - anomalous cast on death
with
Doryani's prototype chest plate

Doryani's main drawback is taking lots of lightning damage, but a suicide bomber doesn't care about not dying. Everything else is just loading up on power charges (other charges don't matter, since we can't do non-lightning damage), and doryani's means that everyone is vulnerablet o lightning. stacking lightning resist to -150 or even -200% is fairly easy, and I think that a basic PoB indicates that the discahrge would hit for somewhere around 100M damage (single hit) - is that enough to one shot the bosses?

The jewels for a discharge suicide bomber can get prohibitively expensive, and I was trying to find a way to downgrade costs, but found a doryani's prototype that I wanted to use, I guess.

try seismic its cheap and usually the 'go to' bosser every league
