So we organised an in-game Secret Santa for our D&D 5e game, and I got our dear half-vampire (monk work-around). She is terrified of insects (ironic, I know).
I would like to give her a pair of sunglasses, but imbue them with a spell, that changes the appearance of anything you're scared of when worn.
Our DM is allowing a rule of cool to a certain extent, as long as it's not ridiculous. How can I make this work using existing spells, or anything similar?
If it's just insects, you could try a simple Minor Illusion (make insects appear as lights, or really anything else you'd want) along with the first-level bard/paladin spell Heroism, which grants immunity to being frightened + temporary hp equal to your spellcasting ability modifier for a minute? If you're a bard you can just do this yourself but otherwise find a fellow player/npc to enchant it (talk to your DM). As for making it react when your friend sees insects, you could prooobably use the "hold an action" mechanic long-term with the glasses? Again, talk to your DM about making all this possible, but those are the best two spells I can think of to make this sort of thing happen.
