A Hearth Fully Upgraded

Overview

Hearths are the heart of the settlement. Every settlement starts with an Ancient Hearth and can construct other Small Hearths from the City Buildings menu. Hearths are buildings with Warmth Specialization Warmth Specialization that employ a single Firekeeper to keep the Hearth lit by burning Fuel. Every villager takes their breaks at the nearest Hearth to warm themselves, eat, and fulfill their needs. By upgrading the Hearth with decorations, housing, and Service buildings, you can unlock up to 3 tiers of stackable benefits. The Ancient Hearth can get corrupted at Veteran Difficulty and higher.

Corruption

Corruption bar in the Ancient Hearth
See also: Blightrot

Blightrot infects Hearths. The more Blightrot Cysts a Viceroy generates from Rain Engine use or Glade Events, the faster their Hearths get corrupted during Storm Season, when Blightrot Cysts open up. Once the Ancient Hearth reaches the Corruption limit, it triggers Voice of the Sealed Ones. Voice of the Sealed Ones sends out 3 ghosts from the Ancient Hearth that seek out and kill 3 random villagers. As soon as the Hearth discharges, Corruption is reset to 0 and starts rising again.

The only way to lower Corruption during Storm is to employ the help of Blightfighers in a Blight Post. Once all Cysts have been burned, any new ones will not open up till next Storm Season. Any Cysts left close and Corruption resets to 0 as soon as the year ticks over and Drizzle Season starts.

Corruption Resistance is a measure of how high the Corruption limit is. The higher the Corruption Resistance, the more time it will take for Voice of the Sealed Ones to activate. An Ancient Hearth that hasn't been upgraded has 1000 Corruption Resistance. Every Ancient and Small Hearth level raises Corruption Resistance by 150. It can also be raised with different Effects.

The Corruption rate per Cyst is 60 Corruption/minute up to Prestige 10, and 90 Corruption/minute from Prestige 11 onwards. Assuming a Hearth upgraded to level 2, you will reach the Corruption limit of 1300 at least once without burning any Cysts:

  • At 60 Corruption/minute in a 2-minute Storm with 11 Cysts.
  • At 60 Corruption/minute in a 4-minute Storm with 6 Cysts.
  • At 90 Corruption/minute in a 4-minute Storm with 4 Cysts.

Fuel

You can decide which type of fuel will be burned in each Hearth by selecting it and using the checkboxes next to the fuel types in the selection UI. If you have multiple fuels selected, the leftmost one will always burn first.

Villager Breaks

Main article: Breaks

Every few minutes villagers have to return to a nearby Hearth for a break, to eat, rest, and satisfy needs. All consumption happens during breaks. Villagers of different species take breaks at different Intervals.

Break Interval 02:00 02:00 01:40 02:00 01:40

Hearth Upgrades

Decorations Needed

Upgrading to level 2 and 3 requires you to unlock levels of the Brass Forge. Click on the Hearth to see what is required to Upgrade. As seen on the image on the right, we still need 4 Comfort Decorations (Green) and 4 Aesthetic Decorations (Blue) before the Hearth Upgrades.

  • Houses and Decorations need to be placed within the Hearth Radius for it to count towards the Upgrade.
  • The Hearth Upgrades itself automatically once all the requirements are fulfilled.

Every Settlement starts with an Ancient Hearth which must always remain lit. If the fire goes out, all Villagers will lose 20 Resolve. To keep the flame burning, a Firekeeper and a steady supply of Fuel is needed. Your choice of Firekeeper in the Ancient Hearth will grant your Settlement a specific bonus.

Sacrificing

During especially hard times, you can sacrifice additional goods in the Ancient Hearth to temporarily gain positive effects.

Each Fuel type grants different boons:

  • Wood Wood → 53 units per minute can be sacrificed to give -50 Hostility
  • Coal Coal → 27 units per minute can be sacrificed to give -80 Hostility
  • Sea Marrow Sea Marrow → 27 units Sea Marrow per minute can be sacrificed to give +25% Glade Event working speed
  • Oil Oil → 20 units per minute can be sacrificed to give +25% global production speed

You can have up to 3 stacks of each Fuel being sacrificed at a time.

Hearth Types

Ancient Hearths

The heart of the colony is protected by the Holy Flame. Villagers gather here to rest, eat, and receive clothing. If the fire goes out, people will lose hope.

Small Hearths

Small Hearths cannot be built too close to the Ancient Hearth or to each other - the ranges of your Hearths (approx. radius of 9 squares) may never overlap.

Small Hearths are identical to Ancient Hearths, except you do not receive a Firekeeper bonus and you cannot sacrifice Fuel. It is OK if Small Hearths go out, but Villagers will be unable to rest or fulfill their needs at an unlit Hearth and will instead travel to the nearest available lit Hearth.

Hearth Tips

Since Firekeepers in Small Hearths don't offer a species-specific bonus like they do in the Ancient Hearth, you can take advantage of its Warmth specialization synergy with Lizards.
