Ideogram

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

Ideograms also act as alternative to the altars, such as the small altar, medium altar, large altar and grand altar.

Acquisition

Ideograms can only be constructed by colonists whose ideoligion has them selected as one of their buildings. They require 50 Steel and 25,000 ticks (6.94 mins) of work.

Summary

Ideograms are functionally equivalent to altars. They 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 ideogram 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:

No work facilities or beds (always required)
Room Impressiveness - 60
Room area - 25 tiles
4x column
All floored

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

If the 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 ideogram, you will have to build their own dedicated buildings.

Analysis

While ideograms take up a 3x3 area, it is entirely passable, meaning they do not take any of a room's space.

Small altars can be made of 50 steel, but can also be made out of stone or wood, and take significantly less work, making them effectively cheaper than the ideogram.
