\subsection{Arcane Gate}\label{arcane-gate}

\emph{6th-level conjuration}

\begin{itemize}
\tightlist
\item
  \textbf{Casting Time:} 1 action
\item
  \textbf{Range:} 500 feet
\item
  \textbf{Components:} V, S
\item
  \textbf{Duration:} Concentration, up to 10 minutes
\end{itemize}

You create linked teleportation portals that remain open for the
duration. Choose two points on the ground that you can see, one point
within 10 feet of you and one point within 500 feet of you. A circular
portal, 10 feet in diameter, opens over each point. If the portal would
open in the space occupied by a creature, the spell fails, and the
casting is lost.

The 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 sid
that functions as a portal.

Any creature or object entering the 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. The mist that fills each portal is
opaque and blocks vision through it. On your turn, you can rotate the
rings as a bonus action so that the active side faces in a different
direction.
