I know these are like super late because I was away for about a year, but the work you've been doing is SO good I feel compelled to give more suggestions to round out your classes.
Class Ideas:
Bard: A traveling story teller, musician, singer and poet. They travel the world, soaking up lore, folk tales, culture, and personal interaction. Often found around trading posts, or bustling, smoke filled taverns, these socialites and pioneers of the arts are imbued with the rare ability to captivate and entrance listeners using only the power of sound. Be it the spoken word, a note sung aloud, or an instrument stroked by the soul, they can use sound to allure, hypnotize, lull to sleep, inspire, reduce to tears, or invoke a primal fear.
Weapon: Bladed Harp
An elegant, but deadly instrument. Amidst the inebriation and bustle of a night out at the local tavern, it may appear to be nothing more than a decorative, exotic instrument gifted to the player by a queen or nobleman, but upon a closer look by a trained eye, the bladed edge and handled shaft for wielding are clear to see.
Some images for inspiration:
Falconer: (The concept was a druid-like beast master who uses beast familiars for his primary attack/skill set. Thinking about a good "weapon" for that, I settled on a falcon) A skilled beastmaster, outdoorsman and survivalist. They prefer to be in and rely on nature, and can form bonds with wild beasts with almost supernatural ease. Often found in the wilderness or around fur and trapping posts, these hunters and wildmen are masters of nature and the animals who defend her sanctity. Be it trained pets or nearby wild animals, they command beats to do their bidding, putting their unique strengths and skills to work for them.
Weapon: War Falcon
Intelligent, deadly, and highly trained. This majestic predator remains at the ready to defend it's master or carry out any order given to it.
