110w

the main focus of this build is spell damage

 

when you get to lv 94 you should switch your helm with this

cause spectre was nerfed this patch, this is like spectre 2.0 i think

 

This is like the perfect compliment to maelstrom, but that negative strength and defense ;n; I'll have to look into it.

 

why do you even have stre and def? O_O

 

I'll have to use a nebulous to compensate for the lack of defense.

 

When you get to lv 93 change the pants to dark channeler. Then change both rings to 2/4 mr and bracelet are clock bracelet for damage and clock necklace for def and now you have the 2 set bonus. With this you have mana regen, damage, even more damage, and some defenses

 

I think i'll use Capricorn for the boots.
