Brainkeeper's mask

The Brainkeeper's mask was obtainable by defeating the Brainkeeper boss. The Brainkeeper's mask will morph certain places of the map when held, such as spawning a monster in front of spawn that gives a badge when touched. The mask emits particles of a weird guy's face when held. As of July 10th, 2020, the Brainkeeper boss teleporter is broken due to Roblox updates, making the Brainkeeper's mask currently unobtainable.
