Type Light
Price 2,500 gp
Weight 1 bulk
Rose gold and copper rings in this +2 resilient chain shirt form a vague bird shape. The jingling links tinkle musically, almost like birdsong. While you wear the armor, effects with the auditory trait must first counteract the harmonic hauberk or they have no effect on you.
The harmonic hauberk attempts to counteract Silence spells cast on you and 4th‑level or higher heightened silence spells the first time the armor enters their area (counteract level 4, counteract modifier +20). After failing to counteract a silence spell, the armor can't attempt to counteract the same spell again, even if you leave and enter the spell's area multiple times.

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.
FlexibleThe armor is flexible enough that it doesn't hinder most actions. You don't apply its check penalty to Acrobatics or Athletics checks.
FocusedAn item with this trait can give you an additional Focus Point. This focus point is separate from your focus pool and doesn't count toward the cap on your focus pool. You can gain this benefit only if you have a focus pool, and there might be restrictions on how the point can be used. You can't gain more than 1 Focus Point per day from focused items.
IllusionEffects and magic items with this trait are associated with the illusion school of magic, typically involving false sensory stimuli.
InvestedA character can wear only 10 magical items that have the invested trait. None of the magical effects of the item apply if the character hasn't invested it, nor can it be activated, though the character still gains any normal benefits from wearing the physical item (like a hat keeping rain off their head).
NoisyThis armor is loud and likely to alert others to your presence when you're using the Avoid Notice exploration activity.
