going oom is normal on blast furnace .
And depends where u healing in p 1 too.
i could recommend u use wrath to dps in p 2 . it will give u a real huge mana save with spirit and will make everything easier.
Also @ p 1 start with dps with heath of the wild. ıf u re healing on left side ( mnot healing foreman group) u dont need to heal really . only reju on bomb ones , mushroom and wild growth when blast would be more than enough. just dps adds, help bombs.
@ p 2 use wild growth and if u really need badly b4 ppl kills adds from p1 , u can use tranq too. But dont forget to dps u need all ur cds on p 3. @ p 3 u can go oom . its really normal . But u can use ur cds turn by turn. First use tranq , then tol with hotw.
Dont ever use wild groth auto! alwasy use it manually . Mushroom too.
i recommend u to save mana pot for p 3 , i always enter p 3 with % 85 mana @ least but if u go oom early in p 2 u can use channeling mana potion there.
But always try to save mana pot for p 3 , u'll use insane mana there and will go oom really fast
