On more than one occaision, I've wanted to farm the first floor, and have had it cut short by a Priest and whitesmith completely dominating Surtur.
Would it be possible to have it so that you can stay on the first floor for like 30 minutes or more after surtur's defeat (like a load bearing boss) where you gotta Get out before that World/dimension/realm collapses and destroys your exp with @nuke and a penalty. Maybe have it save you out in the middle of the fields with the loli ruri's when you die that way too.
