The Prism Shield has the appearance of a French horn. It has a blue star in the middle of it (red when it's almost completely done for). A transparent rainbow umbrella is projected out of the instrument's bell.
The Prism Shield has similar properties as Parasol's passives. As long as it is being held, the item projects an prismatic umbrella shield above its carrier which shields from both enemies and projectiles. While holding it, characters cannot fly or float and will drop it if they are injured.
It has its own feature segment in the Item Challenge.
