1. Silla/Kuvayama (second persuasion of El Hamazi). Sharpshooter-Historian-Something else (merchant?), future mage. Skill: pistol/musket, light armor. Constellation: unknown

For Kuvayama, there's also a fun combo if you play as an archer, in the form of taking a fire spirit with him. Not only will you improve Kuvayama's fragility and weakness, but you'll also be able to make two shots for 99 damage.
