Another use of altars is [[sacrificing]].
Note by Phennexion: If you are trying to make an altar for Priest of a different religion, i.e. you are a black lighter and your priest is Vynora, you can build the altar, and have your priest put the last piece of the altar on by unclicking faithful and attaching the last piece. Works for wooden and stone altars. Underground altars will still give their bonuses above ground, for example, underground altars will spawn mycelium above ground, however you will not receive the domain message moving through these underground altars.
== Types of altars ==
There are four types of altars. Wooden altars are the worst type, gold altars are the best type. The metal altars can be created inside each others domain, while the stone and wooden altars cannot. However, you can move or finish an altar in another domain. Although metal altars are the best type they do not override the influence of a lesser altar, for example a 50ql stone altar will override a 45ql gold altar, the type of material the altar is made out of does not make the influence stronger or weaker. Metal altars seem to give gifts and [[potion]] more frequently.
