Unfortunately, one of the things from Morrowind which did not make it to Oblivion was the ability to make damage spells which target self. And in Skyrim they had removed the ability to make your own spells entirely.

In Morrowind I used this to create an extremely long-lasting fire spell dealing 0 damage to self. The result was a spell which cost barely any mana and resulted in you walking around engulfed in harmless flames. A really cool visual touch.

Are you sure? I have memories of making a spell that targetted myself and gave me 1pt of fire damage that I could spam to train my evocation skill (or whatever it was called).

This was 12 years ago, so it's possible that I don't remember the details correctly. I thought that "self" could not be selected for fire damage, but looking up videos of spellmaking in Oblivion this seems to be possible.

I do distinctly remember being unable to recreate that one fire spell, though. Perhaps it was not possible to set damage to 0 in Oblivion? That was part of why the spell became so cheap and allowed for extreme duration.
