Well, for clown, you definately need elite guitar, clowns are very expensive to be good. So, if you looking for a cheap class. An obvious one would be sinx.
But for clown, 2-3 kiels, 2 elite guitars, Incant, 2 Turtle General, golden ring in one guitar, in the other 1 Stormy knight, 1 Dragoon Warlord, 2 White Smith. Usakoring inside of a forsaken buckler, 2 FBH, 1 Hollowring, OR 1 Raydric, and Sinx Card
This all adds up to about 400 coupons, have fun. (This DOESNT include forsaken set D:)
Cloak, come out, Arrow Vulcan, if it does shit damage, break their shit with the other guitar, if still bad, just do a regular attack on their ass and strip their sheild, beat the shit out of them, if they pneuma, use Jupitel Thunder, THE END
