Bossing Guide

How KuroMS expeditions work, what Pitch Perfect coins buy, and every boss from Balrog to Damien with level, HP, time limit, rewards and drops. Values verified against the game server on September 24, 2026.

How expeditions work

Expeditions are a primary way to meet players, tackle challenging content and progress. They are the main source of Pitch Perfects (KuroMS Boss Coins), exchangeable for White Scrolls, Chaos Scrolls, Clean Slate Scrolls and more.

Completing one grants all party members EXP and Pitch Perfects; bosses also drop equipment/materials.

Key rules: Expeditions have a six-player maximum. Daily bosses target about 10 minutes and Weekly bosses about 20 minutes. Missed entries are stored until the weekly reset. Bosses are tuned so an expedition gives roughly 1.5 levels of EXP for players in the intended range. Zakum Jump Quest and most prerequisites are skippable. Hosts can use widgets to create expeditions. Expeditions are reached via the Widget or Dimensional Mirror in FM.

Difficulty, timers and extra rewards: Papulatus through Horntail let the party leader pick a difficulty from 1/6 to 6/6. It scales boss HP, drops and Pitch Perfect, but not EXP; the numbers in this guide are the 6/6 values. Horntail and Chaos Horntail timers reset per stage, so a full run can take about 30 and 40 minutes. Clear rewards also include Blessing potions and boss keys (Pink Bean, Von Leon, Cygnus, Magnus, Gollux).

The coin is also called Perfect Pitch. It is the same currency; this guide uses "Pitch Perfect" throughout.

Balance notes

Some bosses intentionally have very high HP. If a boss is unclearable after completing the relevant region and obtaining necessary items, players should report it. Pink Bean's HP was lowered from 9b to 4b temporarily while Chaos-boss HP is reviewed; updates are handled in the Bossing Guide.
