This is from a lvl 20 perspective: how you get to this point is up to you...
Raise Dead Ward 4 + Soul frenzy, soul power 3, Divine Justice 3, Surge of Faith 3, and morale 6.
(requires roughly 108k gold (which is easy to reach if you farm reinforcements/minions)) godplate, all fathers ring, Ashkandor, Girdle of the Giants, Mageslayer. Deathbringer, Orb of veiled storms, cloak of flames.
with this build your stats should be around:
10k hp, 5.5k mana, 3.5k armor (58.8%), ~700 weapon damage, 0.50(+66%) attack time, 6.9 movement speed, and you regen health and mana rediculously fast.
You don't have to spend the points on the raise dead ward but I don't play without my spirits normally because they are great support units and extra units to keep enemies busy. also minions help as well especially preists, I personally use the Ammulet of teleportation as my favor item. it lets you get ahead of the competition to flags and get away from them in a hurry.
