I love Slay the Spire! But I'm a little confused about Act 4 and Ascension levels.
I have made it beyond the 3rd boss and attempted Act 4, although I have never defeated it. If I am not mistaken, I unlocked this when I defeated the 3rd boss with each character (3 of them; the Watcher was not yet released). Since that time, when I play, I need to obtain the three items necessary in order to unlock Act 4.
That's with one save slot. The other save slot has unlocked Ascension Mode for all 3 original characters, but when using that save slot, there seems to be no way to advance to Act 4--the three items are not available.
Any ideas what needs to be done to unlock Act 4 on the second save slot? I must be missing something.
