Tal’s meteorb sockets?

I use full

Tal’s set on meteorb sorc for MF. Is it worth putting

Topaz and

Ist in orb/

Helm/armor or should I do facet’s or something else?

The armor is where I socketed an

Ist. I prefer just running the 3 piece

Tal combo (

Belt + ammy + armor) with a

Shako +

Death's Fathom for more damage and potentially more MF.

Got a similar build -

Glacial Spike + Blizzard + Firewall. Armor is socketed with

Cham (so no need to use Ravenfrost or Rhyme shield),

Mask is fire-faceted, and the orb got an

Ist to fill. Pretty much tangible and versatile setup, where you can either swap

Ist for another facet, or insert an

Um into the

Mask, or whatever. If you got skills/resists/other necessary sweets covered by other gear - there are plenty of options, really - so it comes down to personal taste.
