Here is how you setup the auradin (anti caster).
Hand of Justice - zerker ax or cresent moon
Dragon - Mage AND 3 socket 45 res shield (Low str elite)
Dream - Bone Visage
Max out Salvation, resist fire, resist lighting, and conviction
1 point in charge/holy shield
Stats
STR - 55 or 90 depends on which weapon is hoj
DEX- base
Vita- ALL
Ene - base
And you have to have HOJ and both of the Dragon.
1 dragon = 300-450 aura damage
2 dragon = 1480-1600 aura damage
all 3 = 2983-3100 damage
1 dream = 1-3k damage
Hope this helps
