The three chapter-end bosses
Each chapter closes at a Master Nightmare arena. Approach the circle to begin the final showdown; in Overtime, teleporting to the arena starts it immediately.
| Chapter | Region | Chapter-end boss |
|---|---|---|
| 1 | Dark Hills | Tentacle Master Nightmare |
| 2 | Storm Island | Faceless Master Nightmare |
| 3 | Avalon | Claws Master Nightmare |
Optional bosses by chapter
Optional bosses appear as points of interest and reward high-rarity loot:
- Chapter 1 (Dark Hills): Brigit, the White Lady · Mother Ghoul, Underground Terror
- Chapter 2 (Storm Island): Karkinos, Scourge of the Reefs · Abu Al Jann, Father of all Jinns
- Chapter 3 (Avalon): The Coven (The Mother Witch, The Crone Witch, The Young Witch) · Melion, the Cursed Knight
Side-quest bosses
Some bosses only appear inside side quests, which are guaranteed in every chapter:
- Jack’s Quest (Ch1): defeat the Ogre so Jack can escape the Dark Hills.
- Cyclop Quest (Ch2): rescue Sinbad from Steropes, the Cyclop.
- Roc Peak Quest (Ch2): help Sinbad tame Simurgh, Herald of the Skies.
- Crann an Oir (Ch3): help Morgan defeat Arthur, the Fallen King.
- Mordred’s Quest (Ch3): help Morgan defeat Mordred, the Usurper.
The epilogue boss
After Avalon, the Epilogue opens the House of Nightmares — defeat the Nightmares to reach Baba Yaga’s house, then defeat Baba Yaga to finish the run.
How to approach any boss
- Upgrade at the Altar of Heroes first. An Altar is guaranteed in every chapter; spend Dream Shards there before the arena.
- Bring an aggro source. Pied Piper’s rats or Geppetto’s Dummies pull the boss’s attention off squishier heroes.
- Learn the telegraphs. Bosses deal their biggest hits on telegraphed attacks; positioning beats out-levelling.
- Use your trait’s escape. Snow Queen’s Intangible shatter, Beowulf’s Shield, and Melusine’s Move stance all exist to dodge a lethal swing.
Per-boss attack patterns are documented individually on the wiki; this guide covers the roster and escalation. Pair it with the enemy guide and the chapter guide.
