Excellent! KBScanner shows 2 Ancient Knowledge scrolls sold in shops in my game (Elon and Rusty), so I only need to grab a couple more to shoot for level 60.
I made a dubious decision in getting Level 1 Stone Wall over a second upgrade towards the digging chests (would have been 2 chests/1 altar), but I'm very early in the game (just cleared Debir) and hopefully I get to dig 3 chests per battle soon.
Again, I commend you unicornxp for a killer run.
