Spells that give no xp

I am doing a fun playthrough where I am not allowed to gain xp of any kind. I have a lot of prep I have done to take on all the questlines, but there is one thing I am trying to figure out: a use for my magicka.

I'm trying to find spells that give no xp that I can use. Here is what I have so far:

vampiric drain: This was what I started with, and the heal is decent and the damage is cheeks. But being a vampire has been a pain. Sun is annoying and the fire weakness is adding to the list of things that can instakill me. So I'd rather stay normal when I can.

flame thrall: I can get the spell and it gives no xp... but being able to cast it is another story. I probably can't use this til much later in the game.

summon arvak: This is great if I am in a place where it works... but sadly it cannot be used indoors.

conjure ash guardian: I can't get it since I'd have to buy it and I would get speech xp.

cloak spells supposedly give no xp but from my testing they do when they damage enemies. Freeze says it gives no xp on the wiki but it does.

Anyone have any other suggestions? I don't have AE or any CC content.
