Here is my current gear:

Occy
Tal Armor - Um'd
Shako - Um'd
Tal ammy
2x Nagels (28%)
48% War travs
Tal belt
Magefists
perfect spirit mon

Cta 5/5/2 + bo spirit
18/18 sorc torch
14/18/8 anni
16x 7% mf scs
Perfect gheeds

my fire resis is 52
Lightning and cold resis are maxed
Psn resis is 47

Should I replace my perfect spirit mon for the storm shield that I can Um and sacrafice the 35 % FCR? or no.

Im trying to keep the FCR + have max resis if possible. Im not running max block or energy shield. Ive been able to solo mf Chaos + baal just trying to see if theres any way to improve my MF sorc.

1) replace nagels with any other rings
2) replace shako and ocu with full tal
3) put facets in your gear
never) use stormshield on your pvm caster

tal rasha is for noobs

i didnt like full talrashas as I got more mf outta occy + shako :/ I dont remember what % is diminished returns

if you have a p spirit monarch u should sell it and get just a 35 fcr monarch
Id replace a ring or two
You have such a large amount of mf its excessive

blizz I assume?

I started off as a orber and was running a Death fathom. respeced into light, replaced insight with infinity + 3.5k eth fort + vgaze merc and started soloing chaos + baals.

shako
enigma
hoto 40
arach 20
spirit M 35
WT booties or rare resist ones
magefist or 40mf chanchies depending on u'r ring/amu choices to hit hit 117fcr BP

enough mf and stronk damage

with light dmg>mf
