New to playing the mage and have couple questions

[Infectious]

1) Hit najena get your 4 pet focus items.
2) Summon pet (fire) send it on mob.
3) When mob is at 5% back off pet, reclaim energy.
4) Summon new pet
5) Hit mob with a nuke that does 3% of more
6) Send pet to finish and get full exp

At your level it might be easier to just heal pet and take the penalty. Duno though played mage before the nerf
