Rover

Rovers are rangers who quickly adapt to the terrain they are travelling in and protect themselves and allies from the dangers. They have both offensive and defensive capabilities along with few techniques up their sleeve for survivability. Unlike other rangers they are not bound to their terrain but make whatever terrain they are in their own.
