I've heard that dungeons lock on to a certain level based on your skill level. Does anyone know if this happens:

- When you first enter the dungeon?
- When you discover the dungeon in the wild?
- When you accept a quest?

Hopefully, it isn't when you accept the quest or discover it in the wild. I've travelled around quite a bit, and discovered certain caves that I'd like to go back to.. would be a disappointment if I'd locked it in at a low level.

When you enter the dungeon.

EDIT: Supposedly when you clear a dungeon it removes the lock.

I don't think they lock at all.

Dungeons I cleared out at level 1 that have respawned since, have level appropriate spawns in them for me at level 45.

It's this one.

Awesome, thanks.

Yes I think the lock just refers to when you enter the dungeon. If you don't beat all the foes their level will stay locked so you can go back and best when stronger but once cleared they will respawm tougher enemies to match your tougher level at that time.
