I thought he was pretty cool because he was using Frost Spike and melee to kill some Frostbite spiders.
As I'm building my home I ask him to mine some Quarried Stone.
He tells me "No, not possible"
I thought to myself "Oh, he needs a pickaxe"
I get him one and he still tells me "No, not possible"
Tell him to mine some clay "No, not possible"
Some Iron Ore "No, not possible"
This guy is probably the laziest housecarl I've had so far.
I even caught him taking a moonlight swim in my fish hatchery.
