Summonner / Fire Build

Hi everyone, first I apologize if I make mistakes, i'm not english.

Today I decided to play again PoE and make another character so just before I want to make a build that suit what I want.

From what I saw on YouTube, the build that can suit the best what I want may contain:

- Minion summon

and

- Fire damage everywhere FTW!

So I would like to know if it's possible to have a build that pull a lot of fire dmg, summon pets that tank / dps and fire totems at the same time?

I've made this build in a few minutes, it gives a lot of bonuses for the invocations, % elemental damage / crit with staff and some totem buff too.

Sorry for the up, just to add that I took templar to have more global resistance when i'm playing alone, a friend told me that i can tank easily with this character (because i took a lot of resistance like chaos) than if i was taking a witch?
