Infernalist Witch minion build with low budget

Hi !

As the title say I'm looking for a minion build for my Infernalist Witch. My gear is not good but enough to get +5 minions level, resistance capped and around 450 spirit (all ascendances done btw). My goal is to do T15s chill, I'm not pushing anything else yet.

I started with Arsonist build/Raging Spirit but visually is too much and sometimes I get killed by something I didn't see.

Low budget because and beside Infernal Hound, all my skills gems have only 4 sockets and no divine orbs (but got exalts).

Any builds suggestions ? Also, I'm PoE 2 noob and played the first one for like 20 mins :D

I've been running a detonate dead minion build with infernalist. T15s are no trouble with fairly modest (i.e. costs exalts, not divines) gear. It hits very hard thanks to the unique threaded light focus, and with grim feast you have plenty of recovery. Almost nothing survives a single cast including rares but the targetting is a bit finicky at times (avoid Ritual).

https://maxroll.gg/poe2/pob/b874k0zw is the end-state but my gear is nothing like that. POB doesn't calculate ES properly for Infernalist (Beidat's Hand) so the actual value is a fair bit higher than shown.

It's a fairly active build, but the visual noise is low. I know you're looking for a minion build, but I'm suggesting this since it's very cost efficient and pretty much just uses normal minion infernalist gear.

Yeah SRS and firewall is so flashy.. I switched to storm mages just becuse of it. its just too brite dare I say almost eye cancer. post nerf srs i found i don't use that anymore. my acendency is lich but i have infernalist in standard.

I'm running ice mages (ice bomb) with frost bomb and hypothermia to lower resistances.
Using echo, muster, penetration and bidding with the ice mages.
Build out for spirit, reduced reservation, minion area effect, minion damage and minion resistances.
I am running 1 of each minion type for muster buff and the rest ice mages.
I don't currently have the dog still need to finish my ascendancies.
I have also switched over to armor/energy shield and use a shield for extra defenses.

With 1500 life 2000 ES 57% armor and 37% block T15 maps are easy to survive.
Ice bomb has a real lag between casting and the explosions so plan for the delay.
