I've killed the Queen and I'm done with the game till Ashlands.

Some things I'd wish they did a little different with the biome is keep the mist but why, oh why did they also have to make it extremely jagged and steep. I get that they want to sell the Feather Cloak since slowfall is a big deal but the combo of mist + rough terrain is pretty brutal.

The Infested Mine hunt is NOT fun and like you said the rough terrain + mist makes it a nightmare to find them at times. I think the blue dwarf outposts should have a map or something on the walls that will reveal the nearest Infested Mines like those stones do for bosses. Something to make finding them easier...

Let us upgrade the Wisplight with some refined eitr and a black core. This upgraded wisp would clear a lot more mist or even turn the mist more see-through.
