Sounds like it’s just RNG. These last two days of bountiful delves gave me max rank curios for all of Brann’s abilities. Before than I only had 1 or 2 max rank curios. I guess I just got crazy lucky for them.
I’ve gotten all of my missing upgrades this week, over something like 30 bountiful 8s. They drop, not from every bountiful, but from a fair proportion. Prior to tuesday I had one 4/4 curio, having done over 100 bountiful 8s.
… so what I’m seeing here is that curio upgrades are --only-- dropping from T8?
Was this stated anywhere to be intended behavior and I missed it?
