Was just playing through the Iron Outpost dungeon hoping for an enchanting table, when I came across the cube that improves the weapon you put into it if you can find it again. Oddly, I didn’t hear the tell-tale humm that I usually hear around it.
I put in a weapon, the cube up and vanished, and then when the room was empty, the tell-tale hum started up. This doesn’t seem quite right.
