Bot Fly is a passive item.
- Grants a fly familiar that orbits Isaac and fires shielded tears at incoming enemy shots.
- The shots are homing when affected by BFF
- This item's behavior (and pickup quote) could be a reference to the roguelike FTL: Faster Than Light's Defense Drones, which orbit the player's ship and shoot down incoming attacks, like the Bot Fly.
- This item has the same name as a real-life insect whose larvae bury themselves into animals.
