Messenger

The Messenger is an enemy in Marrow.

Description
The Messenger exists in long corridors. It shuffles back and forth and will begin firing projectiles when the player draws near. Much like the Watcher, the Messenger's projectiles will drain the player's luminosity. The Messenger is immune to physical attacks and attempting to attack them will cause a backlash that damages the player.

They are best dealt with by shooting fireballs down the corridor from outside their attack range.
