Extensive Study. Whether you were trained by a mentor, an organization, or simply learned on your own, you have focused deeply on a couple of different planes. The two planes you choose as your focus of study will determine what languages you know, your equipment, and your Resonance feature. Resonance. In your training as a planeswalker, you have grown accustomed to the slight, harmonious vibrations that are present throughout the very fabric of reality. When you are within 50 miles of a planar rift or waygate, you can sense its presence and direction. If the plane is one which you have studied extensively, you will be aware that the rift leads to that plane.
