Idea 2 for 99 Nights in the Forest: Based off entry 1 "Blood moon cultist mask" they have the ability to summon these monsters that attack the player. If the player defeats them, they have the chance to drop a "cursed grimore" (Maybe a future design) that the player can use to summon these deer demons. These deer demons will obey anyone with the grimore and will help fight enemies for the player when in possession of the grimore.
