I have so many slots to fill but i realy dont know how so can somebody help me please ?

 

1) Few skills require DP to be used. For assassins it would be wind walk, divine strike, vaizel/triniel dirk, spiral slash.
2) Atk, Crit, M.Acc is normally what you'll desire for pvp, but I suggest you get better gears first.

 

Get Leather gear, aim for Anuhart Set or something similiar

 

So all the other mana stone like block , pary and the other to dont use ? And what are better the yellow mana stone or the white ?
