The winning side raises its boss on Halloween

The Hollow Moon ends on Halloween. Every Veil Tear your covenant wins counts toward the finale, and the Last Night tear in the Haunted Grounds counts the most. When it closes on October 31, the winning side decides which final world boss rises: Nethros Unveiled for the Lantern, or Hallowmaw for the Hollow. Only that boss appears this year, and only it drops its pet egg. It stays in the world boss rotation until November 7.
