Medium altars are miscellaneous buildings added by the Ideology DLC which act as a focus for colonists to perform, and take part in, rituals.

It is the second smallest size of altar, larger than the small altar but smaller than the large altar and grand altar. Altars also act as alternative to the ideogram.


Medium altars can only be constructed by colonists whose ideoligion has them selected as one of their buildings. They require Stuff 100 Stuff (Metallic/Woody/Stony) and 15,000 ticks (4.17 mins) of work.


Altars or ideograms are used as a ritual focus for the Social party, Animal sacrifice, Scarification, Blinding ceremony, and Prisoner execution rituals. Starting these rituals in an altar increases their ritual quality by +20%, increasing the chance for a positive outcome.

If the medium altar is chosen for an ideoligion, a proper temple room will be demanded at either moderate or high expectations. These expectations are reached at 80,000 or 180,000 colony wealth, respectively. Once expectations are reached, altar rooms can have the following requirements:

These requirements, and the level of expectations where they apply, can change each time you regenerate the altar.

If the altar's room requirements aren't met, then colonists will gain a −4 <Altar> disrespected moodlet, or −4 Missing <Altar> if nonexistent. They only apply once moderate / high expectations are actually reached. For example, you can place an altar inside a bedroom until you reach the expectation threshold. Altars are instanced per ideoligion; even if 2 ideoligions use a medium altar, you will have to build their own dedicated altar.

  • Styles[edit]

    Ideoligions allow the selection of styles which then change the texture of the certain items and buildings when constructed by the colony. These style variants can be crafted if the colony has the selected style, or can be looted from raiders from factions with the requisite style.
