Lunar altar

The Lunar altar is built in the Achievement Gallery of a player-owned house as a place where players can switch their spellbook to the Lunar spells. Other players can use the altar, provided they have completed Lunar Diplomacy.

The lowest level at which the altar can be built is 75 Construction, using the +5 boost from a spicy stew. The crystal saw cannot be used to lower this requirement, as the Achievement Gallery room requires 80 Construction and is unaffected by the saw.
