Some magics retain the Ghost transparency when using them following using the Ghost magic. This continues to happen until you re-enter, or change rooms. I have noticed this happens with the following magics, though there may be others.
- Dancing Inferno Blue
- 4th Fireworks
- Turn into Push
- Villainous Curse
- Ice Block
- Pixie Dust
- Confetti
- Levitation
- Snowfall
- Cursed Storm
