Is this right or am I missing anything?

Hellwarden's will -8 with 10/10 guardians light
2/20fcr amulet
15md void
Enigma
HoZ (can be upped)
Sling ring -5mr
Soj
Gheeds wager belt -7mr/15+fcr
Horazons boots (cbf, stats, magic resist)
Magefist

125fcr, max resists depend on charms, 20k hammers with -30 magic res

Magic sunder is godlike now and makes it so you can kill anything efficiently

What weapon do you use on merc ?
If its Insight then BK over SoJ.
Same for Trangs over Magefist.
Otherwise whats your weapon of choice/merc of choice and setup ?

Also with this setup you achieve 130 FCR so you dont need more than 15 FCR on ammy if you get a 20 Gheeds. Can play with Ammy and Gheeds FCR roll.

And if we go on the -magic res might aswell get the -magic res sunder rather than the magic dmg one for up to -40.

I wouldnt enjoy playing Sunder elsewhere than areas that dont have magic immunes tho. Unless they are magic immune you can just crush em and the -magic res from the setup seems enough for magic resistant enemies.
Btw what do you socket your HoZ with in an ideal scenario and what would be your ideal 2/20 ammy there ?

Is there a way we can discuss the best hammerdin build further ?

since +skills benefit hdin alot and void doenst give -magic res i think hoto might be better.

at least i tried it that way on p8 single player, even killed baal wave 2 pretty reasonable.
didnt do any math tho.

hoz / 10

We (they) did the math and Void beats Hoto everyday.
