The Monstrous Moon is the third and final part of the Lunar Battle equipment quest line. It is a boss quest with an eponymous boss, and it can be unlocked by checking in to Habitica 40 times. Monstrous Moon's HP (1000) makes this a long quest and its strength multiplier (2) makes this a medium difficulty quest. Without using Warrior or Mage boss damaging skills, a four-person party can typically finish this quest in between three and four weeks.
