Thats good site for crafting planning

You need to do it with faceted fossil

I would try Faceted fossil + Sanctified fossil + Aetheric fossil (this because it close so many mods from pool)

126damage at lvl20
208damage at lvl25, effectivniss of added damage is 25%

208-126/0.25/1.27archmage=258 extra mana payed when use Archmage-blade vortex, will outdamage +5skill level


Indigon helm 2000%spelldamage will make you pay that 258extra mana, and will remove all required damage from passive tree/gear/+6.66skill gem lvl
