Hot take but "See Invisibilty" should always reveal something
Like, we only really deal with the dangerous naturally invisible creatures, but there's also species of birds and insects and plants and so forth that are invisible. There's invisible rock formations (ever trip over nothing?). Invisible clouds. Invisible works of art. You cast See Invisibility and suddenly there's an entire invisible ecosystem that you can never really interact with normally.
Also you finally find out there's actually been a gnome sitting on the barbarian's head and livetweeting your adventures this whole time
