Not to be confused with the Mask + Heart monster

The Mask of Infamy is a two-stage boss found in Necropolis.


During the first stage, the boss consists of a Heart and a Mask - only the Heart will take damage. The mask cries out of her left eye socket. Both the mask and the heart float around the room, the mask moving faster. The heart occasionally shoots an 8-way spread of bullets. The mask charges after the player, similarly to the Selfless Knight.

During the second stage, the Mask's eyes bleed much more profusely, and it takes on an angrier face. During this phase, the heart is gone and the face can take damage through the small hole in the back of the mask. You must attack the side or backside of the mask to damage it, unless you have piercing weapons (similar to a Knight). Neither stage has a health meter.

As of v1.33 an AI buff to knights makes Mask of Infamy incredibly difficult to defeat without piercing or crowd control. The mask makes 180 degree turns much more often, and nearly instantly will turn to face and charge the player if they attempt to approach from behind. However, it is possible to defeat the Mask with the use of poisoning items such as the Pinky Eye if the player can evade it long enough to drain its health. Another useful item would be The Pinking Shears as the separate body will follow closely behind at all times and makes for a quick fight. Another good tactic against the Mask of Infamy is to use an ability that slows down the mask (such as Spider's Bite or Little Gish) which can help you to get shots at its back. An effective, but risky, strategy is the use of bombs. When the mask charges at you, you can drop a bomb and hopefully the mask will be close enough to the bomb to recieve damage. If nothing else, speed is necessary to win the fight. Charging along perpendicularly to the Mask and shooting tears will damage it but the Mask won't charge. Focus on shooting as many tears as possible and being fast and the fight will be long, but possible.
