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.
