Sanctum Fireball build

I'm looking for a Fireball ignite build with good defense and OK damage to farm with peace of mind (if it's available, I'd like it to be a starter build, if not, that's fine too)
I always look for fireball ignite builds in poe ninja and I always find "ward loop" versions but I don't like the gameplay of ward loop, I wish it was self-cast fireball.

Thanks guys ❤❤
