The Lookman was an hostile entity in The Lost Mines, appearing only in The Attic.
Appearance
The Lookman takes on the appearance of a tall, shadowy humanoid silhouette with glowing white eyes that turn purple when looked at.
Behavior
The Lookman behaved similarly to Eyes. The only difference is that the Lookman damages a player once, then teleports to a different position. Furthermore, its audio cues are very quiet, making it difficult for players to detect the presence of the Lookman.
It had a chance to spawn in most rooms and made a low rumbling noise. If players looked at its eyes, it would attack them, briefly darkening their vision and teleporting to a random place in the room while making a thumping noise and causing the lights to flicker. The Lookman would despawn when the next door is opened.
