Sorry - I’m a nube and not that far into the game, but a couple of times I’ve come across objects that look a bit like small icicles - but that seem like they are steaming. I found a couple in a block of ice I melted.
Any clues as to what they are or their utility?
The steam from the icicles and ice block are them melting. You might have fused it to a weapon/shield in a cold area and then equipped the item in a warm area.
If you are in a cold area and you are seeing steam off ice then you have a elemental weapon equipped or fire shield or something.
