Not just for ubers, but for everything...maybe a little bit of pvp too. Here is my gear so far

Coa Ber Ber 29/29
Enigma Dusk (also have coh)
Grief pb 39/388
Gore rider
Exile Vortex Perfect base 45 resis
Tgods (also have dungo)
Drac Grasp
Raven/Bk
Maras

I have smite, holy shield, fant, and defiance max out....Should I redo him and instead of maxing defiance...should I max resis light, resis cold, and resis fire in that order?

cant remember ias breakpoints but seems pretty good/standard

resist lightning is good to put last points on

So I should redo and take points out of defiance and separate them into resis lightning, cold, fire?

probably no. Just use the rest points into resist lightning to get max lr. You don't need cold/fire.

what level u even?

I'm level 81 currently

One more advice. Go do few more dia/baalruns
