As usual I placed a lantern into the dark ahead of me right next to a troll‘s head, lol. I hastily retreated and build a wall to stop the troll, who was following me. He gave up and returned but to my surprise he continued walking to the right beyond his base! He was trying to go the long way around and attack me from behind!
Troll is in the bue circle, if you look closely you can see my BH in the red circle.
