The Huilu is a unique wand found alongside the note spells on a platform on the upper right-hand side of the Cloudscape directly above the bridge spanning the Frozen Vault chasm. It can be used to play the note spells in specific combinations to cast a spell. Each melody can only be used once, and playing the same pattern after that will have no effect.
Note that the Huilu is not required for playing the melodies; any wand will suffice. For a list of known melodies, see the Musical Curiosity page.
- During early access, the Huilu was originally named the Ocarina, and is still referred to by that name in the game files.
- Huilu is Finnish for flute.
