Value of my Hailstone Gyre Clasped Orb?

12% chance to cast level 4

Nova on striking
1 to sorceress skill levels
2 to

Chilling Armor
3 to

Energy Shield
2 to

Thunder Storm
5 to life
cold resist 35

I would say nothing because of only +1 to sorc skills and imho most people are looking for lightning,

Nova, blizzard,

Frozen Orb,

Fireball,

Hydra or

Meteor instead of

Chilling Armor,

Energy Shield or

Thunder Storm.
