Speaking of buying rules, the rules say: All purchases “stack”, making a purchase will not cause you to lose another.
But when I read the description for Indulgences, presumably buying the First-Class Indulgence (“Keep up to 20% of your Blood Shards when Ascending”) does not mean I’m intended to keep any previous indulgences. That is, if I have a Basic Indulgence (up to 5%), and I buy the First-Class Indulgence, I don’t get to keep 25% of my shards, just up to 20%.
Is that the intention?
If I get the Just Bury Me With It indulgence, I think it makes sense that I can only keep up to 100% and wouldn’t get to keep a maximum of 405% (making more shards somehow) if I had all of the other indulgences, but on the other hand, maybe?
