Hi guys, I would like to know how to improve my stats to be able to 2-bar derk ( or at least rota)

Right now im a lvl160 wiz with those stats in bm2 + aura :

1285 m.atk
51 rate
154 crit dmg
46 amp
1197 def
14 add. dmg

My current gear is :

30%crit dmg lapis+9
5/20 lapis+9
8/20 osmium helm
EoS+7
3x 7%amp pieces
BoS+3 slotted x2
K-red
AoP+5
CR+2x2
RoL+1
Merg ring

My BM2 bar is :
Met(15) - EDC(18) - HS(20) - SC(12) - AF(20) - SCan(20) - LCan(20) - FCan(20) -
Vac(20) - ACan(20) - CE(20) - TL(20) - FL(20)

Can anyone give me some advice on how to get a better DPS(Something that would really help right now, not something that would make me hit 8s more)

I dont really care about def/hp right now.

Any tips on what to get next(considering price) would be appreciate,

Thanks
