Planeswalker

Through some encounter with magic both great and terrible, you have gained the trait that has made legends in Ravnica, Theros, Strixhaven, and beyond: the ability to walk between planes. You gain the following traits.

• As an action, you teleport yourself to a different plane of existence. If you have been to the target plane, you can specify a target destination in general terms, such as the City of Brass in the Elemental Plane of Fire, and you appear in or near that destination on the specified plane. If you have not been to the target plane, you must make a DC 15 Intelligence (Arcana) check, and on a failure, you teleport to a location on that plane of the DM's choosing. You teleport along with your equipment and anything you are wearing or carrying.
• You learn one first-level spell from the sorcerer, warlock, or wizard spell list, which you can cast once without expending a spell slot before a short rest. Your spellcasting ability for this spell is Intelligence, Wisdom, or Charisma (your choice when gaining this feat), and you may also cast this spell using your own spell slots of the requisite level if available.
• You exhibit a visual, auditory, olfactory, and/or otherwise sensory phenomenon when you appear or disappear by the Planeswalk action. Decide how this phenomenon manifests. Examples might include jumping from a whirling blue vortex, walking through doors made of light, or tracing flame in your steps while running into another plane.
