\subsection{Call Lightning}\label{call-lightning}

\emph{3rd-level conjuration}

\begin{itemize}
\tightlist
\item
  \textbf{Casting Time:} 1 action

  \textbf{Range:} 120 feet
\item
  \textbf{Components:} V, S
\item
  \textbf{Duration:} Concentration, up to 10 minutes
\end{itemize}

A storm cloud appears in the shape of a cylinder that is 10 feet tall
with a 60---foot radius, centered on a point you can see 100 feet
directly above you. The spell fails if you can't see a point in the air
where the storm cloud could appear (for example, if you are in a room
that can't accommodate the cloud).

When you cast the spell, choose a point you can see within range. A bolt
of lightning flashes down from the cloud to that point. Each creature
Within 5 feet of that point must make a Dexterity saving throw. A
creature takes 3d10 lightning damage on a failed save, or half as much
damage on a successful one. On each of your turns until the spell ends,
you can use your action to call down lightning in this way again,
targeting the same point or a different one.

If you are outdoors in stormy conditions when you cast this spell, the
spell gives you control over the existing storm instead of creating a
new one. Under such conditions, the spell's damage increases by 1d10.

\textbf{At Higher Levels:} When you cast this spell using a spell slot
of 4th or higher level, the damage increases by 1d10 for each slot level
above 3rd.
