What is the limit for his power? (specific weight, etc.) Any specific materials he cannot control? For example, this is common in fantasy - fey cannot touch or manipulate metal.

What about the side effects if he overuses his power? (ex. vomiting, dizziness, etc.)

These are some questions - great OC!
