You cant get scatter, never was never made. mabey on other private server there was such a option when u reb(i saw once;P was fun OO) but not on this one.
best combo is Water-Tro-War
u get cyclone, and also thunder /stigma(this is good cuz stigma make u strogner, and if u got Poision blade , than u might have a chance to poision ur enemy from a distance with useing thunder while ur poision blade on u, and as much attk u got with the blade , as grater the dmg will be.
