@Cydira when you ascend a die (lvl 100) it gives you some, lets say card points, "Card progression per ascension" means that the die gives more points when they ascend, after getting a lot of cards, specially gilding them, it start taking a lot of points to get a card
Awful hitboxes man, they hit you all teh time, and you can barely hit them back... not to mention those things that follow you arround and are impossible to shake off
