I am starting a campaign soon, and wanted to make some homebrew classes, about 3 or 4 in total. I want to make 2 martials, one half caster, and an int based caster. one idea I have for the martial is the gunsmith. they would be like long ranged monks, using int instead of wis and having some kind of point system similar to focus points. They would make "eldritch firearms" which are basically modern guns but with magical damage such as thunder. other than that, open to any and all ideas!

For an int based caster, I like the idea of a psychic, as spells could easily be reflavored as psionic power. Some of them actually are!
