It's currently only found in Arcade Mode, as G-Meister said the chest reward got changed in the season temple so there is no way to currently get a hold of the Axe (unless the cheat command /equip gives you one, I'm not sure what gear it gives you)I keep hearing about this "Lumber Axe" but I've searched seasonne as well as the temple of seasons and found nothing. Help on how to get it?
