Quest artifact

A quest artifact is a special artifact that you retrieve from your role's quest nemesis. You need not even pick up your quest artifact to ascend, but you must somehow defeat your nemesis for the Bell of Opening, so you might as well pick it up.

Each quest artifact has an alignment. You can only pick up a quest artifact that you share a role and/or alignment with. You cannot wish for your own role's quest artifact. Also, don't wish for a cross-aligned quest artifact unless you intend to convert yourself.

Finally, each quest artifact has a few special effects. For example, The Orb of Fate not only invokes for a levelport, but it also halves any physical damage you receive. Since The Orb of Fate is also a crystal ball, you can also apply it to get the normal crystal ball search-for-a-glyph effect. See the entry for a particular artifact to find out all of its effects.
