thana slayer GS ehh...
on shield put GTB, "usakoring has nothing to do with it coz thana is not demi human. you have gec so dont worry about the sp cost"
on cloak put 2x raydric, thana damage is neutral then dont worry... his damage has no thana effect. :p
ifrit cards has nothing to do with your damage with desperado, better use dex runes.
you have a good armor..."but if youll find hardtime on tanking his damage you can use gr+tao"
and also you have good weapon card.. "some use inca+3abyssmal, you may try it as well..."
any bullet except neutral(bloody shell/regular) will do good since thana is ghost property.
the rest are good the way i see it. :3...
