Invoke

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

Artifacts tire after you invoke them, and you cannot do so again for rnz(100) turns (averages 100; can be up to 2000, but 95% of the time it is less than 400). If you invoke again too soon, "You feel that the <artifact> is ignoring you" and 3d10 turns are tacked on to the wait time.

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 Mitre of Holiness: boost in spell energy.
• 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.
• The Platinum Yendorian Express Card: charges objects like a scroll of charging with the same blessed/cursed status. Only Tourists can perform blessed charging.
• The Orb of Fate: level teleport.
• The Longbow of Diana: creates 7-16 uncursed arrows if uncursed, 7-21 blessed arrows if blessed, 6-11 cursed arrows if cursed.
• The Master Key of Thievery: untraps boxes and doors with 100% success.

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