RPG - Jojo's bizarre adventure

[Power Systems Lore: The universe has three main distinct power systems. A character can only use one, and ordinary humans have none.

1. STANDS: Visual manifestations of life energy. Strict Rules:

• Only Stand Users can see, interact with, or harm other Stands.
• Non-users (Humans, Vampires without Stands) see absolutely nothing when a Stand is summoned. They only see objects flying, walls breaking, or people getting punched by an invisible force.
• Damage to a Stand is fully reflected onto the user's physical body.
• When the user dies, the Stand vanishes.

2. HAMON (Ripple): An ancient martial art based on controlled breathing that produces energy identical to sunlight. Highly lethal to Vampires/Zombies. Cannot be seen easily, but manifests as golden electricity around the user's body/weapons. Does NOT grant a Stand.

3. VAMPIRISM: Biological enhancement via the Stone Mask. Grants immortality, extreme regeneration, flesh buds, and ice-freezing abilities. Weak to Sunlight and Hamon. Does NOT grant a Stand unless pierced by a Stand Arrow.]
