what he said ^
card wise, get:
Helmet: 2 kiels
Weapon: incantation sam. card, 2 turtle generals, 1 skel. worker
Armor: Preference
Cloak: assassin eremes card, hollowring (you'll need the sp), you can also check out pouring card.
shoes: 2 FBH's
vote and get the kobold archer hat (40% more dmg with bows)
2 dex belts/ 2 ND dex belts
utilized traps, cloak, arrow repel, DS, arrow shower (better than detect to reveal cloaked enemies, use detect for people hiding)
i would use ghost arrows and wind arrows
BTW, regarding putting int for sp, there really is no need because DS wastes only 12 sp... not alot really. you'll need sp more for your buffs lol..
have fun.
