\subsection{Programmed Illusion}\label{programmed-illusion}

\emph{6th-level illusion}

\begin{itemize}
\tightlist
\item
  \textbf{Casting Time:} 1 action
\item
  \textbf{Range:} 120 feet
\item
  \textbf{Components:} V, S, M (a bit of fleece and jade dust worth at
  least 25 gp)
\item
  \textbf{Duration:} Until dispelled
\end{itemize}

You create an illusion of an object, a creature, or some other visible
phenomenon within range that activates when a specific condition occurs.
The illusion is imperceptible until then. It must be no larger than a
30-foot cube, and you decide when you cast the spell how the illusion
behaves and what sounds it makes. This scripted performance can last up
to 5 minutes.

When the condition you specify occurs, the illusion springs into
existence and performs in the manner you described. Once the illusion
finishes performing, it disappears and remains dormant for 10 minutes.
After this time, the illusion can be activated again.

The triggering condition can be as general or as detailed as you like,
though it must be based on visual or audible conditions that occur
within 30 feet of the area. For example, you could create an illusion of
yourself to appear and warn off others who attempt to open a trapped
door, or you could set the illusion to trigger only when a creature says
the correct word or phrase.

Physical interaction With the image reveals it to be an illusion,
because things can pass through it. A creature that uses its action to
examine the image can determine that it is an illusion with a successful
Intelligence (Investigation) check against your spell save DC. If a
creature discerns the illusion for what it is, the creature can see
through the image, and any noise it makes sounds hollow to the creature.
