I statted my Champ (with all equip on):
STR: 296+134 important is to keep it on a base of 10 [eg 296+134 =430) to get a bonus on attack
AGI: None, i kill onehit....or at least try it^^
VIT: 98+50 Just to be able to survive most of the normal attacks of players (important for SinX, they can kill instant as well)
INT: round about 150, Important is to get nearly 6000SP, thats the maximum for Asura, more over does not deal more dmg
DEX: 150 for Instant Cast
LUK: none
and equip as mentioned from its777, i also use the forsaken kings armor with tao
