Coaler

Coalers are coal-like enemies which burst into flames once they take damage, causing them to move and fire faster and more erratically.

Behavior
Coalers walk towards the player, occasionally shooting at the player. Upon taking damage, they will burst into flames, causing them to move around erratically and release flaming bullets in random directions. Ignited Coalers may also light pools of oil on fire, by means of a small oil trail they leave. However, they are not invulnerable to fire damage once ignited, with the exception of their own oil trails.

Trivia
