Marvelous Calliope Level 4
Uncommon Conjuration Magical Structure
Price 100 gp
Bulk L (when not activated)
Usage held in 2 hands
This large slide whistle appears to be made of fine brass, the sides of which are engraved with musical notes and dancing clowns.
1 minute (command, envision, Interact);
Effect You blow a tune upon the slide whistle, causing the whistle to expand. The whistle sprouts from one into several, and then creates a large wooden frame and keyboard. By the time the unfolding is complete, the whistle fully transforms into a calliope, a wagon-sized contraption consisting of several steam whistles played like an organ. The calliope is heavy and anchored in place.
You have a +1 item bonus to Performance checks to play the calliope. The calliope has a tendency to produce music for a few seconds after you cease playing it, adding a jaunty and overlong conclusion to your music.
If you use an Interact action to pull the small metal ring on the underside of the Marvelous Calliope, the calliope collapses back down into a slide whistle.
