Well,you should d-lvl the wizzard mastery,which you can do by doing the 'skill relocation quest' that you can start from every potion seller.Its simple - gather cursed hearts,which drop from all mobs,and for each 10 cursed hearts you can d-lvl one skill only once.But Warlock is kinda hard for a beginner,since you have to change weapons alot,spam many skills and a hard tactic.While the wizzard is simple as 1,2,3 so i decide staying wizzard.Its up to you i helped as i could .
