The Bat Devil is a contract-granting entity located in City Outskirts.

Key notes

• Found inside a house in an open field (often described as left of the tunnel highway).
• Grants Bat-themed abilities (e.g., roar / AoE).
• Requires a human sacrifice as part of the contract process.

Tip: Prepare the requirement beforehand—this contract is often considered socially risky due to the sacrifice step.
