There is an event for being crowned "Hand of Elebereth" and so forth
and an event for being given an artifact (any, not just the first) as
reward for #offer, but there wasn't one for the item usually given
along with being crowned.
Now there is. It's not something that an observer (of the events
being logged) can deduce since sometimes an alternative is given
(wizard and monk) and other times nothing is given (artifact already
exists or lawful character isn't wielding non-artifact long sword).
I flagged the spellbook given to a wizard or a monk as
'divinegift | artifact | spoiler'. 'artifact' since even though it
isn't actually an artifact, it is standing in the place for one. And
'spoiler', to hide from #chronicle, in case the hero doesn't know the
spellbook yet.
