Alarm SnareConsumable 1
Source Pathfinder Core Rulebook
Price 3 gp
Weight negligible
You create an alarm snare by rigging one or more noisy objects to a trip wire or pressure plate. When you create an alarm snare, you designate a range between 100 to 500 feet at which it can be heard. When a Small or larger creature enters the square, the snare makes a noise loud enough that it can be heard by all creatures in the range you designated.
Traits
Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.
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.
ConsumableAn item with this trait can be used only once. Unless stated otherwise, it's destroyed after activation. Consumable items include alchemical items and magical consumables such as scrolls and talismans. When a character creates consumable items, they can make them in batches of four.
MechanicalA hazard with this trait is a constructed physical object.
SnareTraps typically made by rangers, snares follow special rules that allow them to be constructed quickly and used on the battlefield.
TrapA hazard or item with this trait is constructed to hinder interlopers.
