Are you on Ladder or Non-Ladder?

If you're on Ladder - Griffon's Eye Diadem is the perfect helm for ANY Lightning Sorceress.
+100-200 Defense (varies)
+1 To All Skills
+25% Faster Cast Rate
-15-20% To Enemy Lightning Resistance (varies)
+10-15% To Lightning Skill Damage (varies)

If not, I always love the good ol' Shako. Can't go wrong with +2 skills, +life/+mana and 50% MF.
