Interact
Effect The bone begins recording the next 1 minute of ambient sounds (including speech) that require a DC 15 or lower Perception check to hear. The bone's recording doesn't copy magical auditory effects, such as those of spellcasting, a harpy's song, or a banshee's wail. Once the rhythm bone has been activated in this way, it retains the recorded sound for the rest of its existence and can't be activated this way again.
Activate Interact
Effect The bone replays its recorded sounds.
Craft Requirements Supply a casting of Ghost Sound.
Traits
Something of uncommon rarity requires special training or comes from a particular culture or part of the world. Some character choices give access to uncommon options, and the GM can choose to allow access for anyone. Less is known about uncommon creatures than common creatures. They typically can't be summoned. The DC of Recall Knowledge checks related to these creature is increased by 2.
AuditoryAuditory actions and effects rely on sound. An action with the auditory trait can be successfully performed only if the creature using the action can speak or otherwise produce the required sounds. A spell or effect with the auditory trait has its effect only if the target can hear it. This applies only to sound-based parts of the effect, as determined by the GM. This is different from a sonic effect, which still affects targets who can't hear it (such as deaf targets) as long as the effect itself makes sound.
MagicalSomething with the magical trait is imbued with magical energies not tied to a specific tradition of magic. A magical item radiates a magic aura infused with its dominant school of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
