You can get one per day.
Until you faint again, then the newly lost items replace the old ones.
That’s good to know, thanks! Ironically, I ended up getting careless and losing all my health, so this came at the perfect time.
Regardless, I’m sticking to my answer of 10HP in the mines, especially with that refresher. A set 1000g as opposed to items and money lost, and more money spent to get it back depending on what it is, makes running out of energy seem not so terrible. Especially as failing this time took a good chunk of my money, about 6000g out of about 85,000g total. The harsher consequence makes simply running out of time pale in comparison.
