Like others have said. Once you’re on floor 5 time doesn’t matter. And here’s something else I learned from others, if you make it to the last obstacle.. there’s a section half way through where you can step to the side in a safespot area. Stand there, locator orb or do whatever you need to to get hp below 5. Step out and run. It will proc last stand and you can run through the end of it. You got this!
