A question for anyone who might have an easier time tracking it and a bit of knowledge I think I've figured out after testing a bit.
Does anyone know what modifiers the blessings use? Do they all use magical might? Do some use Physical, or perhaps they use the higher of the two/a hybrid formula using both? I've tried keeping an eye on it but the numbers fly about too fast, mostly curious for the sake of optimizing memories.
On that front (if anyone's curious) I believe levels are seeded in possibly the most annoying way, they stick with a seed until you play it through even if you do another level. For a bit I thought, perhaps, that one could farm rare memories by checking through all the levels that had the one you wanted to farm, and if none did, you could do an event level/trial or whatever and try again. Sadly that's not so, though I haven't checked if seeds reset on daily reset.
Also, keep a warrior in your backline. It's the only class whose 'active' ability works for the whole party, and it activates quite often even at level 1. I was stupid and didn't realize this until I'd already leveled my whole group to near 40 with a Thief, Monk and Mage 🫣
