Warn before one-chance-only content

As per title. It's extremely frustrating to do an activity during leveling/story, die, and suddenly find out you can't retry it, when the game at large lets you retry bosses and areas until you succeed.

The Architect in the Vaal Temple while leveling apparently can only be attempted once and if you die you lose your entire temple run. Nowhere was there a clear warning/information about this, so it left a very sour taste in the mouth to die to it and find out there isn't a second chance.

Every other challenge in the game while leveling so far has been something I could retry if I died, so this felt very arbitrary. This is something I might expect from clearly defined end-game challenges, but not an event during leveling.

(Note, I'm not asking for a change in the mechanic, I'm asking for clarity so that the player knows that it works unlike anything else up until that point.)
