  \textbf{Casting Time:} 1 action
\item
  \textbf{Range:} 120 feet
\item
  \textbf{Components:} V, S, M (a small piece of phosphorus)
\item
  \textbf{Duration:} Concentration, up to 1 minute
\end{itemize}

You create a wall of fire on a solid surface within range. You can make
the wall up to 60 feet long, 20 feet high, and 1 foot thick, or a ringed
wall up to 20 feet in diameter, 20 feet high, and 1 foot thick. The wall
is opaque and lasts for the duration.

When the wall appears, each creature within its area must make a
Dexterity saving throw. On a failed save, a creature takes 5d8 fire
damage, or half as much damage on a successful save.

One side of the wall, selected by you when you cast this spell, deals
5d8 fire damage to each creature that ends its turn within 10 feet of
that side or inside the wall. A creature takes the same damage when it
enters the wall for the first time on a turn or ends its turn there. The
other side of the wall deals no damage.

\textbf{At Higher Levels:} When you cast this spell using a spell slot
of 5th level or higher, the damage increases by 1d8 for each slot level
above 4th.
