Each time you rebirth, you get a certain amount of Dark Blessings, which you keep even if you rebirth again.
You can spend Dark Blessings in the Church to unlock upgrades, and those upgrades are also permanent, they are not lost when you rebirth.
For example, if you rebirth and upgrade Tempered Steel to level 1, you will spend your 5 Dark Blessings, but the Tempered Steel passive will remain at level 1 permanently, even after future rebirths.
So yes, the rewards are cumulative. The only things you lose on rebirth are your XP, Gold, and floor progress.
That part might be a bit confusing in the UI, I’ll take a look at improving it.
Thanks again for your feedback :)
