I'm hosting my first session of Dungeon World and we are having a great time, but some controversy came up during play. One of my players is playing the Ranger class with no hacks or anything. His race is elf as well. The passive for the Elf Ranger says that "When you undertake and perilous journey through wilderness whatever job you take you succeed as if you rolled 10+". I'm confused about the wording, does this mean that they always roll 10+ on the Perilous Journey Move or do they succeed at everything involved on the mission. For example my player wanted to track and kill a bear in the woods constituting a perilous journey through the wood. Does the Elf Ranger passive mean that he also rolls 10+ on all his combat rolls against the bear as well?
