Jujutsu kaisen styled Blox Fruits game

Hello! Im Nathan and im a solo developer of a game that im developing right now, Its based off of jujutsu kaisen, where you unlock diffrent abilities, cured techniques, cursed weapons, and become a sorcerer or a curse, but currently i have no idea what to start on, i have a combat system (Not finished, still requires cursed technique combat) and a starter map with 4 empty places

If anyone could help me design something to put in those 4 empty spots on the map i would be very thankfull!
