Help with warlock build

Hello, im new in this server, but not new in ragnarok. I've played in another servere a long time ago, but i've never played with the 3rd class, so, i woul like to have some tips with this new type of class, specially with warlocks (I was a HW previously). So i would like that anyone could rate a skill build that i made and help me to develop a stat and equipment build.
Since now i'm grateful...

This is the skill three for HW that i used in the past.

-Fire Bolt lv. 5
-Cold Bolt lv.5
