You craft an illusory object, creature, or other effect which executes a scripted performance when a specific condition is met within 30 feet of the area. You must describe both the condition and the details of the performance upon casting. The trigger must be based on something that can be seen or heard. 

Once the illusion triggers, it runs its performance for up to 5 minutes before it disappears and goes dormant for 10 minutes. The illusion is undetectable until then and only reactivates when the condition is triggered and after the dormant period has passed. 

You magically hide away a willing creature or object.

You sculpt an illusory duplicate of the target from ice and snow. The duplicate looks exactly like the target and uses all the statistics of the original, though it is formed without any gear, and has only half of the target’s hit point maximum. The duplicate is a creature, can take actions, and be affected like any other creature. If the target is able to cast spells, the duplicate cannot cast spells of 7th-level or higher.
