There’s a way of exploiting The Witcher 3: Wild Hunt to earn lots and lots of money, and it involves rolling a beehive into town and then having the bees sting and kill a dwarf, obviously.
It’s Essential, as we wrote in The Witcher 3: Blood and Wine review.
The town is White Orchard (the starter town), the dwarf is a smith called Willis, and the beehive is a beehive on a tree down the road.
The Willis corpse-mountain you’re building you can loot for whatever money he had on him when he died.
