The Priest's Powers of Construction

Use your High Priest to build Temples, Workshops, and Altars, and (in multiplayer mode) Outposts on any large island--including your own first island. Right-click on him and select the appropriate option. The building will go to your cursor, ready to be placed. (Note that your Priest must be able to walk to the build location.) Once you've placed the building, the Priest will walk to it and begin construction.

Note that a Priest cannot construct buildings while immobilized.

Like the Golem, your Priest also serves as a Transport. You can use him to acquire and cast Spells or to transport Storm Crystals. Additionally, the Priest will try to move to a safer location if the bridge underneath him becomes dangerous.
