Comment by Shin on Exiled Duke’s Wife: Light Magic & Past Life Knowledge - Chapter 6

@Shin Don't forget, illusion magic and invisibility. Plus you can use light magic for other more mundane purposes, such as sanitation ultraviolet light, x-rays, sterilization via radiation and photography/videography. Also I can't help but wonder if a light affinity user would be able to essentially cast sunscreen.

And lazer cutting of course. Additionally, We don't know much about the mechanisms behind magic yet, It's entirely possible that electricity falls under the umbrella of light for purposes of magic in this world. There were some Parallel drawn, which could beforeshadowing that two are linked in someway. The story also mentioned that they couldn't keep cattle and pigs because of the cold weather in the winter so perhaps the main character will Be able to use light cast something along the lines of a heat lamp spell. Also, considering that radiation from the sun is what causes heat on earth and that both the sun and certain types of light sources are made of plasma I wonder if she'd be able to control plasma hich would allow her to burn through basically anything.
