I can only recall getting these from Dr Fate daily rewards menu in the past several months. (F1 on Keyboard or the Up D-Pad on Controller) Do these still drop as loot??
Yeah, artifact leveling is at a virtual standstill now, even on 2X bonus weeks. Longing for the weekly Nth metal drops in the vault.
Seeing a stack of 999 Nth Metal seems like a lot, then you see that it is 10XP per and your heart dies a little.
'Drop'? Not that I've ever seen. Loot from Vault, daily rewards, boosters and potentially out of a Nth Metal detector cache (maybe)...but from running content as drops.....nope.
