Epic Boon of Planar Travel

When you gain this boon, choose a plane of existence other than the Material Plane. You can now use an action to cast the plane shift spell (no spell slot or components required), targeting yourself only, and can only travel to your chosen plane, or from your chosen plane back to the Material Plane. Once you use this boon, you can’t use it again until you finish a short rest.

Note that not every plane listed exists in every game setting discuss with your GM before choosing.
