Smart Fly is a passive item.
Effect[edit | edit source]
- Spawns an orbital fly whose behavior changes depending on whether or not Isaac has taken damage in the current room.
- The fly always deals 1.5 damage per tick or 22.5 damage per second on contact with enemies.
- Before Isaac takes damage, the fly serves as an orbital familiar, blocking enemy shots.
- After Isaac takes damage, this fly will seek out nearby enemies and attack them.
Notes[edit | edit source]
- Smart Fly does not take up one of the three orbital slots; it floats between two of the other orbitals.
- Very useful in Boss Rush as it will remain aggressive until it is completed. A strategy for Isaac would be to willingly damage himself right at the start to trigger the Smart Fly so it deals with all the bosses.
Synergies[edit | edit source]
- Duct TapeStops Isaac's familiars from moving.: Fly will stay in place when orbiting Isaac but will still pursue enemies.
- Dull RazorHurts Isaac without depleting health, activating any items that trigger upon taking damage.: Allows releasing the Smart Fly to attack enemies without taking actual damage.
