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.[1]
Some artifacts tire after you invoke them. In this case, you must wait before you can invoke them again. If you do it too soon, a message appears like "You feel that the Eye of the Aethiopica is ignoring you" and you must wait 3d10 more turns.[2]
List of possible invocations
- The Eye of the Aethiopica: branchport to another dungeon branch.
- The Eyes of the Overworld: provides enlightenment.
- The Staff of Aesculapius: heals half HP damage, cures sickness, unblinds, unslimes.
- The Orb of Detection: toggles invisibility on/off.
- The Sceptre of Might: toggles conflict on/off.
- The Magic Mirror of Merlin: gives random rumour, from the true file if blessed, the false file if cursed, or either if uncursed.

- The Heart of Ahriman: levitation; you can stop this levitation with '>' at will, or by invoking the Heart again, providing no other levitation sources interfere.

Invoking a non-artifact crystal ball is exactly the same as applying it.
