As an action, you create two linked teleportation portals in unoccupied spaces you can see within 10 meters of you that remain open until the end of your turn. A circular portal, 30 centimeters in diameter, opens over each point.
The portals are two-dimensional glowing rings. Any object entering a portal exits from the other portal as if the two were adjacent to each other; passing through a portal from a nonportal side has no effect.
When you cast this spell, you can make a weapon attack through the portal (no action required).
The portal is not stable enough for a creature or energy such as alchemical explosions or magic to pass through it.
This spell immediately ends if you cast it again before an existing portal closes.
At higher levels
When you reach 9th level, the portal becomes stable enough for energy such as alchemical explosions or magic to pass through it.
