yes, infinity is mandatory.

full tal set ain't the best lightning set, but should do nicely.

what is your go to?

you want to get to 120 fcr.

hoto spirit 35 20 from gloves 20 from arach a fcr ring

you can use tal rasha armor as it's good for mf and res

shaco on head

another ring like soj or bk

you can also get a 2/17+ amulet and then get two rings like soj soj or bk bk or soj bk

I like aldurs as boots

if you can get grifon on head, then the whole setup changes as that gives 25 fcr. with griphon, you can try cmoon as weapon.
