The Veil Boss Locations & Summon Triggers
Check your active quest milestone before heading into the deeper maze. Encounters like Puppeteer appear at night, while Stormcaller and Smelter Demon require breaking Thunder Quartz or blowing the Smoldering Horn in the deep Veil during nightfall. Matching your inventory to the boss avoids long trips with empty hands.
| Boss Encounter | Spawn Location & Summon Trigger | Recommended Next Step |
|---|---|---|
| Puppeteer | Crumbling Ring arena; spawns during the night cycle | Learn the Puppeteer night route and fight |
| Stormcaller | Shatter Thunder Quartz in the deep Veil at night | Check Disease Era quest progression |
| Smelter Demon | Blow the Smoldering Horn in the deep Veil at night | Deliver Fire Essence to Bobby in Scorch Basin |
| Festering Wound | Ritual altar using Festered Meat | Master Festering Wound cues to clear Disease Era |
| The Cell of Life | Encounter near The Marrow and The Final Descent | Push progression beyond Disease Era into The Pale |
Bosses Along the Main Quest
Let your active quest objective set your route. In the Disease Era, your path leads through The Scorch Basin and altar objectives before culminating in the Festering Wound confrontation. If you want an optional side challenge, head to Crumbling Ring at night for Puppeteer, but focus on the main quest milestones to unlock deeper zones.

Defeating Festering Wound marks the transition past the Disease Era toward The Pale and the Primordial Era. Later footage shows The Cell of Life around The Marrow and The Final Descent landmarks, representing subsequent milestones rather than the end of the game.
Summons and Entry Requirements
- Confirm night conditions: Puppeteer spawns at night and despawns by dawn, while Stormcaller and Smelter Demon require nighttime in the deep Veil.
- Use the correct summon action: Blow the Smoldering Horn or shatter Thunder Quartz at night; do not confuse horn uses with altar placements.
- Pack Sanity restoration and healing draughts to survive maze travel and extended boss phases.
- Verify weapon requirements: Legendary drops require weapon mastery before you can equip them.
- Stay active in group fights: Boss and mob-event chests require reaching at least 20% contribution to open and loot.

Boss Rewards & Chest Eligibility
Under the September 6 update, opening boss and mob-event chests requires at least 20% combat contribution. The announcement sets this threshold without publishing an exact calculation formula, so stay active throughout the fight rather than hanging back.
High-tier drops include legendary items like The Dice from Puppeteer. Legendary weapons require completing the matching Weapon Mastery before you can equip them. Plan your Melee, Casting, or Summoning training alongside your boss hunts.
