Invoke

The #invoke extended command allows you to activate certain objects. The only objects that can be activated this way are crystal balls and some artifacts, especially quest artifacts.

Some artifacts tire after you invoke them. In this case, you must wait before you can invoke them again. If you do it to soon, a message appears like "You feel that the Eye of the Aethiopica is ignoring you" and you must wait 3d10 more turns.
