I have a player who's using the new Unearthed Arcana Update Ranger. They argued that should have advantage on initiative and on their first turn during combat all of the time. As a level 1 ability, I find this to be incredibly overpowered.
The way I see it, Natural Explorer should only come into affect when the Ranger is outside, i.e. not in a building. Currently, the player is inside, in a Mage's Tower.
Does Natural Explorer apply all of the time, or only when outside?
