Add in a torch, anni (of course).

The way I figure it you would need 17 of the facets:
6 socket scepter (6)
4 socket monarch (10)
3 socket demon head helm (13)
4 socket dusk shroud (17)

FLAW: If you are fighting against a barb with the following gear:

P Nord's Tenderizer x2 (Jah'd)
P raven frost x2

P Kira's Guardian (+100%) (Thul'd)
P Metalgrid (+35%)
Snowclash (+15% max cold resist)
Enigma (any type)
Duped rare boots with high resists
Dracul's grasp gloves

Charms:
P torch
P Anni
Inventory filled with p "Sapphire small charm of vita"s

Results:
70% cold absorb
+647% cold resist (and max raised to 90%)
+740 hp.

Backup weapons: two p BO cta (+4 BO each) or failing that two HOTO.

They would be completely immune to anything you throw at them.

Yay for builds meant to take out certain builds!
