I definitely enjoy invisibility, but sometimes I feel like it's too powerful. You can escape from any fight just by casting the spell and running away. Maybe there's a mod that only allows you to go invisible if you're not detected when you cast it? I think supreme magicka removes your invisibility if you're near an enemy who has detect life, have you found that to work well for you? Any other ways to handle invisibility?

My experience with invisibility changing mods is limited to SM, and it works for my purposes. I generally use invisibility only when I want to either get somewhere uninterrupted or if I want to closely observe creatures/npcs. The SM ini also has an option to allow Vampires to see through invisibility and chameleon.

Not too long ago I was observing while invisible and suddenly a message in top right appeared that "so and so had seen through my disguise", or something, and I was revealed to said so and so.
