Thanks in advance

In the ini file you can set consistent summons for any period of time, or sustainable summons that last forever but burn mana slowly. Also you should have it anyway for any magic character, it's "essential" for me.

It also lets you summon multiple creatures at once depending on your Conjuration level, also configurable to your liking. And adds several new spells that summon several at once too.

Advanced Magecraft also allows CE summons.

Druid Mod Remade gives you some nice creature summons, like wolves, that stick around until you dismiss them or they die. They work a little differently than most conjured creatures too, they'll only come if you're outdoors, and you have to wait for them to show up. They don't "appear" from oblivion.
