Mega Mage vs. Shadow - Worth It? Advice?

[WhoIsThis]

1 Armor for antlers.

I should mention that I am wearing a ring:

Fine Champion's Fine Crystal Ring Req: Lv 20, 67 Int; 2% Crit, 2 M/s, 4 Damage (from Physiologic's list)

Edit:

It if it helps, this is before patch 1.7 of me in shadow. Add 30 int, the new set bonus, and the ring and you have the answer.
