Planeswalker Spark

The spark has ignited in you, You always had it but now it has been unleashed by an untold experience you had. You gain the following benefits 

• You make cast Plane Shift as a ritual, to take you to a plane you have been in or have touched a creature or object who was created or born on the plane. Each portal can only be opened once per short rest, and you may only take yourself and your belongings with you. At level 11 you may cast with all the restrictions but as an action, needing no components. At level 17 you may cast Plane Shift 3 times a day as an innate casting ability.
• Once per short rest, You may cast a spell of a higher level using a lower level spell slot (2nd level spell, as a 3rd level spell). The spell must have the "at higher level" text and you must be able to cast spells of the higher level. If you are a Warlock you dont expand a spell slot using this feature.
