Here is my take, gm, strong, with MB and NB swaps:
95 % ES precast.
Max Block setup, blaze for relevant frw, high psn resistance/plr, 105fcr/60fhr/75% block/4,9k mana/18k fireball dmg:
Can swap ammu + belt for dungo setup wiht more DR, or strings for added MDR.
Can swap gloves to death gloves for better anti psn, can also use snakecord etc if want.

Spirit - Upped Whistans
Coh - Viper
Diadem - other diadem
1 or 2 fire life - Fire FHR
Arach - Dungo/Strings
NB setup, more of the good stuff:
