You create a magical effect within range. Choose the effect from the options below. If you cast this spell multiple times, you can have up to three of its non-instantaneous effects active at a time.
Sensory Effect. You create an instantaneous, harmless sensory effect, such as a shower of sparks, a puff of wind, faint musical notes, or an odd odor.
Fire Play. You instantaneously light or snuff out a candle, a torch, or a small campfire.
Clean or Soil. You instantaneously clean or soil an object no larger than 1 cubic foot.
Minor Sensation. You chill, warm, or flavor up to 1 cubic foot of nonliving material for 1 hour.
Magic Mark. You make a color, a small mark, or a symbol appear on an object or a surface for 1 hour.
Minor Creation. You create a nonmagical trinket or an illusory image that can fit in your hand. It lasts until the end of your next turn. A trinket can deal no damage and has no monetary worth.
RAW there's no requirement for the trinket to be an illusion. An Illusory Image is only one of the options for the Minor Creation feature. As long as the trinket is small, has no monetary value, and doesn't require a particular provenance or history (e.g. a twig struck by lightning for Witch Bolt or a vial of blood taken from a humanoid killed in the past 24 hours for Summon Lesser Demons) or a requirement that it last longer than the next round, it should be fine.
