Echo

An echo weapon establishes a lingering sonic resonance within a target. A creature with blindsense or blindsight (vibration or sound) can detect a target hit by an echo weapon at a distance of up to 10 × its normal range. This does not grant blindsense or blindsight to creatures that do not already have this ability.
