FAQ

What do belltowers do?
Ringing a belltower lights it and permanently clears the gloom in a short radius around it, and kills nearby ghosts. Ringing five in one expedition earns the Bellringer badge.
How do you get the Well Rested badge?
Find and eat the Early Worm, which spawns randomly on the ground in the Gloom and moves in a small circle until you pick it up.
How do you get Medieval History?
Climb past the Citadel without being hit by any trap, including the luggage trap's sleeping gas. Patches 2.5.a and 2.6.b fixed cases where loading a save or being revived blocked the badge.
How often do the Gloom and Citadel appear?
They replace the Caldera and Kiln on half of the days: 104 of 208 in the current map pool.

Overview

The Gloom under purple fog

The Gloom (region four) and the Citadel (region five) arrived with the final major update, 2.0.a “The Final Ascent”, in August 2026, and were the only ending for three weeks. Since 2 September they share the ending at random with the Caldera and Kiln; in the current pool they appear on 104 of 208 days.

Tricky ravens Steal your voice
Wrought-iron fences 2.5 Injury per second if you stand on top

Belltowers

Ringing a belltower lights it and permanently clears the gloom in a short radius, killing nearby ghosts. Every Gloom on the current maps has 7 belltowers, so you only need the five closest to your path for Bellringer. Today’s belltower locations list them by position.

The Early Worm

The Early Worm

The Early Worm wanders in a small circle on the ground until picked up. Eating it earns Well Rested. It spawns randomly, so look along the ground as you cross.

Light and protection

Light sources push the gloom back: the Candlestick, Faerie Lantern and the regular Lantern (which does not stop Drowsy). The Book of Bones and the Ancient Idol prevent Drowsy entirely. Burning the Big Ghost with a Candlestick, Faerie Lantern, Portable Stove or belltower earns Exorcist. Petrified scouts in the swamp point toward luggage.

Tips

  • Plan each leg from a high point before dropping into the fog.
  • Thrown frogs can pull you along as a traversal trick.
  • Gloom luggage often has Candlesticks: open it early.

The Citadel

A tower full of traps. There is no campfire and no natural food, and from Peak difficulty up the sleepy gloom rises from the bottom, so do not linger.

Traps

Trap Effect
Arrow traps 7.5 Arrow per hit; pulling an arrow out costs 12.5 Injury; each trap fires 3 times
Spike traps 15 Injury
Swinging maces Up to 25 Injury and ragdoll
Buzzsaws Injury
Spike rollers (vertical and horizontal) 5 Injury every quarter second
Petrifying stones Petrify
Luggage trap Drowsy gas within 16 m
Crucible of lava On the second floor

Golden chains, golden ladders (cheaper, faster climbing), lamps and staircases help you up.

The luggage trap looks like ordinary luggage but sits slightly open with its handle up; Citadel days average about one. The luggage types guide shows how to spot it. The Citadel also averages 1.4 clown luggage, the second most of any region, which helps with the Jester badge.

Tips

  • With high stamina you rarely need gear here; speed matters more than safety equipment because of the rising gloom.
  • Invincibility (Fortified Milk) lets you remove an arrow without taking Injury.
  • Medieval History means no trap hits at all, including the luggage trap gas.

The ending

The top of the Citadel

The stone scout with all four amulets

The top floor has golden scout statues and an archway marked with a star that leads to the Peak right beside the tower. Light a flare to end the run as usual. On Ascent 8, place all four amulets on the stone scout behind the Peak and escape through Nadir instead. If you carry the Ancient Idol from the Tomb, throw it into the Citadel’s lava cauldron for 24 Karat.
