The 13 change caught me off-guard. I was just playing M1 and I was like "wtf 13s have a new effect exclusive to here???" and I checked the deckbuilding GUI and it changed alot so I scrolled down and got jumpscared by an unexpected update
I noticed that past some point, composite stones beyond 100 seem to show up as ? in their descriptions. I found this by playing a 1043-stone. (13 fight)
Also, the fact that 23 is rock and by merging it with 2 makes it become 46, which seems to be some kind of flat rock. If you do so again, you get 92, which is a paper airplane, quite funny I'd say. The evolution is so random.
The almanac should also have some kind of unlock-to-view thing. I'd say that all non-composite stones get unlocked in the almanac when you get them (e.g. you can view 13 in the almanac when you beat the 13-prime master) and composite stones get unlocked when you craft them. (e.g. you can view 6 after you create the 6-gem, by merging a 2 and 3 gem together)
You should add some kind of almanac (not the deck menu type) that's basically an almanac of all stones from 1 to 100, the special stones (negative 1, 0, x, mirrorstone) and the tools plus maybe some the stones after 100.
