Papulatus is on BeyondMS's boss list, and its Papulatus Certificate is one of the three certificates for the Horntail Squad Badge. BeyondMS's Discord has no prequest guide for it. Its regular quests are unchanged from v83, so this page follows the original "Protect Ludibrium" quest line and the v83 boss room.

Requirements

Level: the Protect Ludibrium line starts at level 60. Papulatus itself is level 80 in v83.
Item to summon: Piece of Cracked Dimension, dropped on the crack in Origin of Clocktower.
Party: the party leader enters the boss portal in Deep Inside the Clocktower (v83 instance: 1–6 players).
v83 quests involved: Protect Ludibrium, The Replacement Time Energy, The Time Sphere, A Piece of Crack, Papulatus, The Lost Piece of Crack (regular quests are unchanged from v83, so each one has its own full guide)

Needs in-game check

The Discord guides don't settle these yet. If you know the answer, please update data/sections/bosses/papulatus.md.

does BeyondMS still need the Piece of Cracked Dimension and the Ludibrium Medal, and does Papulatus have a level/rebirth minimum or weekly limit?
Where on BeyondMS do you get a new Piece of Cracked Dimension for repeat kills (v83: The Lost Piece of Crack)?
