8th-level transmutation (Sorcerer,Warlock,Wizard)
- Casting Time: 1 action
- Range: 30 feet
- Components: V, S, M (a handful of earth)
- Duration: Concentration, up to 1 minute
When you cast this spell, a circular portal, 10 feet in diameter, opens over a point you choose within range. You also choose a second point, which can be at any location you have previously visited on the same plane of existence. A second, identical portal appears at that point.
Both portals are two-dimensional glowing rings filled with mist, hovering inches from the ground and perpendicular to it at the points you choose. A ring is visible only from one side (your choice), which is the side that functions as a portal. Any creature or object entering one portal exits from the other portal as if the two were adjacent to each other; passing through a portal from the nonportal side has no effect. On your turn, you can rotate the rings as a bonus action so that the active side faces in a different direction.
The surface of the first portal is transparent, allowing you to see what lies beyond; however, the surface of the second portal is a translucent gray color. This misty grayness is opaque and blocks vision through it to the first portal. Nevertheless, creatures can freely pass through the active side of each portal for the spell's duration.
