PoE chrzan07, Spell builds

Hello pob warriors could somebody help me improve my build? I do not really care about defensives until i cap dot dps w/o flame surge. i have about 30 div to spend but i can easily farm more if needed. mb is not mine and i have to return it to owner at end of the league so i cannot sell it. things im aware i could upgrade: recraft bow on better base with better essences and t1 dot multi recraft quiver to get any useful mods like onslaught / blind / effect of ailments / chaos res better timeless jewel and potentially impossible escape for minion instability to allocate more mods from
