Now I’m even more confused. We have mythstones on every explore level, so this doesn’t really apply:
I’d actually appreciate it if there were a way to throw away all collected mythstones. We get more from each E12 run than we can spend, so they keep piling up. This will be a huge annoyance next vault weekend, because it will catch up by throwing mythic battles into dozens of E1 runs (that possibly trigger E12 mimic battles with E1 loot).
