There will be no Avril Lavigne references in my thread.

Helm should be Shako. Dream does not help Lightning skills at all, since Holys only affect melee damage.

Weapon should be an Eschuta's. It is much better than Hoto, damage-wise. Sorceress don't hit with melee weapons. Ever. And I do mean ever. Same skill bonus (if found properly), and a bonus to damage percentage. By the way, Flails don't actually deal damage once past Normal Act I.

Belt is Arach's.

Both rings should be an SoJ. Bul Kathos is for melee characters only, since Sorceresses don't use Lifesteal or Manasteal.
