Planeswalker (Magic the Gathering)

Minimum Level 8 required. There must be a reason in the story for your previously unlit spark to ignite.

You are a planeswalker, a creature with the innate ability to traverse the multiverse. You can cast plane shift at will as an action or bonus action without expending a spell slot and without material components with the following limitations. You can only target yourself. Other living creatures cannot travel with you. Touching you while you cast this spell does not make another creature an additional target of this spell. Each time you cast this spell, roll a D4. If you roll a 2 or lower, you cannot cast plane shift again until you take a long rest, and you gain a level of exhaustion.
