A while ago, my D&D group had a lengthy debate about what would happen if you cast invisibility on someone holding a torch
In other news, today I saw someone wearing a camo jacket and a high-visibility vest, so I either have an answer or more questions
I think it would have to be the kind where it is basically a brain illusion. If the torch is invisible but still emits light, then the other objects can still emit and reflect light so that doesn’t work. If invisible objects are blocking light somehow then they’d appear as a giant black spot. If they’re bending light than the user wouldn’t be receiving light so you’d be invisible but effectively blind too. So I think it has to be a direct illusion and a torch would be invisible as well
