When you summon something should it stay around tell it dies? I mean you would have to limit the amount that can be cast, but at least things like heal target and the like would be useful.

Maybe like a special quest chain for Conjuration masters that involves ultimately getting a permanent Daedra minion, maybe it could have a name and a personality too? that would be awesome

Another option is have it up but it affect rate of magika regeneration. Or like in Dragon Age you magika doesn't fill up all the way. Move conjuration to a willpower based stat. Same with boons like fortify strength and etc.

Yeah I've been wanting this.
And for balance it negatively affects magicka regen. At some point if you have too many summons it could drain magicka, and when you run out of magicka you can't sustain the summons and they disapear.

maybe it should be a perk?

Maybe it could be an enchantment.

I'd rather have it constantly drain your magicka. That way, the more "experienced" (those with more magicka) players can have summons around for longer.

Definitely a perk. 3 levels (Extend summon time by 25%/50%/ makes them permanent until they die). Works for me.

I would like permanent summons.

This would make conjuration my favorite skill!

Great idea, pretty sure with the perk system your summons will become closer to being permanent. However, wouldn't that make Conjuration level up slower? Well, I guess you could spam your summon spell until you acquired the desired Conjuration level, which would be boring. I hope that you gain exp on things like how many creatures your summoned minion killed or experience gained per hit dealt, not on cast alone.

I also had other few thoughts in my head: If there are 80-85 spells in the game, how many are "Summon X" spells?
If it's one spell named "Summon", does it scale with level, i.e. "Lvl 12 is Skeleton, Lvl 87 is Dremora Lord"?
Will all your summons be damage dealers?
Will they be obedient all the time?
Will the game give NPCs a name based on what it will classify you as depending on what you summon the most, i.e. "Mostly Undead = Necromancer"?
What different kinds of ways can the same summon spell be casted based on how long the button is held down?

I have more questions, but I was rambling after the first paragraph so ignore it if it doesn't interest you, answers will surface soon.

Yes for the ability to somehow attain permanent summons.
