Bit of an odd one today. I’d received Poison Darts from a titan chest, but when I went to have a look at my inventory, the “+1” displayed on Mystic Rings, and not on Poison Darts:
I questioned my recollection and went to check recent activity, where, sure enough, I had received Poison Darts from a titan chest (and no recent Mystic Rings):
I’m pretty sure it’s the inventory label that is confused.
The only other relevant info I can think of, is that I consumed some rings the other day.
