So I know there are games that do have Necromancer classes like ESO and GW2, but they don't feel super Necromancer like to me. I'm hoping a game exists where when I summon something, it doesn't disappear within a minute or only appear for an attack animation, which rules out a Skyrim Conjuration run.

I've also played Diablo and Last Epoch, and Path of Exile.

Do any games like this exist outside of a typical iso-view ARPG? Any genre is fine.

The best sort of example I can think of is something akin to Solo Leveling in how he can summon basically armies that don't just vanish straight away, whereas in ESO for example, your ultimate summons a "Flesh Golem" which appears, slaps the floor a couple times then vanishes.
