Note by Phennexion: If your you are trying to make an altar for Priest of a different religion, i.e. Your you are a black lighter and your priest is vynoraVynora, 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.
