You can only ascend if your alignment record is pious. Otherwise, you either escape in celestial disgrace, or less evilly, your god just rejects the sacrifice until such time as you are pious.

If someone of a different god steals the Amulet from you on the Astral Plane and sacrifices it to their god, your god will hit you with a wide-angle disintegration beam in frustration that you got so close and then blew it.

When you ascend, you receive an elaborate role-specific message with your quest leader congratulating you (if they are alive).

You can go to the Astral Plane early, and by waiting around there long enough, eventually a player monster will spawn with the real Amulet, at which point you must prevent them from ascending and claim the Amulet yourself.

If the hero has see invisible while ascending, swap the line “An invisible choir sings, and you are bathed in radiance…” out for some other YAFM. Perhaps even something as subtle as “A visible choir”.

If you ascend with your alignment mismatching your align0 (meaning you changed alignment at some point), your game-end reason is recorded as “ascended in dishonor”.

Pets anywhere on the Astral Plane always go with you when you ascend, regardless of whether they’re adjacent or leashed to you.
