Worldbuilding

I'm working on making my own ttrpg, a mystery action game where you play as a Psyker , think a combination of Call of Cthulhu and earthbound. The setting is suppose to be sort of a kitchen sink encompassing almost every type of supernatural entity or phenomenon and I'm struggling to come up with an origin and general vibe surrounding magic and witchcraft. I want it to be distinct from psionics with the two not encompassing the same abilities while at the same time making magic useful and interesting in case players want to interact with a potential magic system.

As of right now, most abilities i can think of can easily be done with psionics in some way so what would you say are some distinctly "magic" like abilities that you generally don't expect psionics to be able to do.
