I know you're GC build. Try it... if it didn't work, flame me to hell for days

Probably bathory on silk robe.
P.S. faith reduce GC damage 50%, your tirfing reduce 25%, deviling however increase 50%, shadow armor increase 25%.
Blah Blah, my estimation
(500% GC atk)*50%*(100 - 25)%*150%*125% = you receive 352% your own attack
Without devilling (raydric), (500% GC atk)*50%*(100 - 25)%*125% = 235% your attack
Those are not even full GC damage, it's like seeing 1/4 damage (because they got 2x damage) on monster hit you, should be less with your def and mdef.
With your defense and mdef (extra +20 mdef from kaho, +10 mdef from silk robe), I would not think it was so bad.
put a bit vit though, you don't need that much dex, grand cross is 2 sec, and cast can't be interrupted anyway.
use thara frog/toad on anubis, platinum shield on abbey.
oh gh castle (raydric + wanderer) for random loot
