Mage/Dark Wizard Help Mage Build

Hi I am a level 85 Mage and would like to know from other mages what a good build would be at my level. Also if you know what powders to add to the items please feel free to tell me :)

I am currently using:

Wands- Celebration (With earth, thunder, and water powders on it), Bob's Mythic Wand (With water powder on it), Sunrise, and Ethereal (With fire and thunder powders on it)

Armour- Restored Ancient Helmet, Morph-Steel, Champion Leggings, Champion Boots
(If I did not say what powders were on the item, I have none on it)
