Wondrous Item, rare (requires attunement)
This small whistle is made from bloodforged steel and hangs from a simple braided leather chord. It can be worn as a necklace.
Blowing this whistle calls a specific giant bat to serve as your mount, provided the creature is within a 10 mile radius.
When you fall while wearing this whistle, you descend 60 feet per round and take no damage from falling.
