Fly

Corpse Flies and Sewer Flies are a smaller, faster flying versions of Buzzcutters, which are only spawned by other enemies.

Behavior

 * The Sewer Flies are spawned in groups of 3 or 5 by the Hammer or from a fake chest.
 * The Corpse Flies are spawned in groups of 5 by the Swarm Zombie.
 * Both variants can perform a melee bite attack, similar to the Buzzcutter.
 * However, Corpse Flies will only do so if the Swarm Zombie that spawned them is killed. Otherwise, they will only use their electric fence.

Strategy

 * They can be easily killed with AoE damage.
 * The electrical fence can only be dodge rolled. Try to kill the Swarm Zombie before it activates or roll away and use AoE attacks.
 * Its melee attack can be easily neutralized by rolling or parrying.

Trivia

 * Corpse Flies used to spawn when a Swarm Zombie died.
 * In a previous version of Dead Cells, Sewer Flies and Corpse Flies both shared the name Corpse Fly.
