Blizzard has introduced a new version of the Butcher in Season 5. Now called Burning Butcher, the classic villain comes with horns and lava marks on its body, with a lava charge ability.
Chances to come across the Burning Butcher are relatively slim, he spawns very randomly. But RNG being RNG, one particular player encountered not one, but two Burning Butchers at the same time.
Even though it’s just a screenshot, you can clearly see two Burning Butchers trying to take down the poor player.
The OP said they nearly died trying to take the screenshot. The world of Sanctuary is full of surprises and you never know what happens next!
