I'm asking if the exit key spawn is random or set. such as if I need to open all doors and it spawns behind the last locked door during a run.
Its rng sadly, although I am almost certain that it will always be behind a locked door, Bella on nightmare was rough with bad rng.
Since it's RNG I can just blame my abysmal luck on never winning. Thankfully it isn't set to the last door to unlock, or I'd be 100% screwed. Thanks for letting me know.
