Nice build.
With the area changes RF seems to come out well and you don't need to go for Blast Radius anymore. Cool.

It's alright, pretty much the only thing I have left to work out is a +1 max res kaom's (8ex), a 3r +1 RofF (best I've seen is 2.5ex but I think I can wait and talk someone down), and master crafting some more sweet shit on my already ridiculously gg helm. I only have about 5ex in liquidity right now so we'll see where I go with it.
So far the build has cost me ~600c, which I've collected almost entirely on this same character as I was more or less broke after hobbling together my CI SRS (which is fun and does absolutely disgusting DPS, but has nowhere near the survivability to do endgame proper, and doing LL SRS is fantastically expensive because fotm).
Wep - 4c
Shield - 20c
Helm - 240c
Boots - 90c
Gloves - 60c
Belt - 15c (like holy shit I was so lucky to see this seconds after it was posted, wasn't even live searching; I'll probably try to sell it off later for a +1 endurance belt though)
L Ring - 4c
R Ring - 10c
Amulet - 20c
The only thing I miss from SRS is that I have to pay attention to map mods now. And even then, really the only one I categorically cannot do is the no regen mod; -10% max res and below is doable, 40% less regen is doable, 60% less regen is dicey but doable so long as I'm careful not to drop endurance charges and I flask early and often. I just have to keep an eye out for those combod with vulnerability. That said, this is the first time I've done a super tanked health character and it's a load of fun. There's very little I cannot take on the chin, pretty much the only pucker moments are really high density esh breaches and uber bosses.
