Sanctum}\label{mordenkainens-private-sanctum}

\emph{4th---level abjuration}

\begin{itemize}
\tightlist
\item
  \textbf{Casting Time:} 10 minutes
\item
  \textbf{Range:} 120 feet
\item
  \textbf{Components:} V. S, M (a thin sheet of lead, a piece of opaque
  glass, a wad of cotton or cloth, and powdered chrysolite)
\item
  \textbf{Duration:} 24 hours
\end{itemize}

You make an area within range magically secure. The area is a cube that
can be as small as 5 feet to as large as 100 feet on each side. The
spell lasts for the duration or until you use an action to dismiss it.

When you cast the spell, you decide what sort of security the spell
provides, choosing any or all of the following properties:

\begin{itemize}
\tightlist
\item
  Sound can't pass through the barrier at the edge of the warded area.
\item
  The barrier of the warded area appears dark and foggy, preventing
  vision (including darkvision) through it.
\item
  Sensors created by divination spells can't appear inside the protected
  area or pass through the barrier at its perimeter.
\item
  Creatures in the area can't be targeted by divination spells.
\item
  Nothing can teleport into or out of the warded area.
\item
  Planar travel is blocked within the warded area.
\end{itemize}

Casting this spell on the same spot every day for a year makes this
effect permanent.

\textbf{At Higher Levels:} When you cast this spell using a spell slot
of 5th level or higher, you can increase the size of the cube by 100
feet for each slot level beyond 4th. Thus you could protect a cube that
can be up to 200 feet on one side by using a spell slot of 5th level.
