Magic Item, Simple Weapon, homebrew
Rare
Properties: 1d4 piercing – finesse, light, thrown (range 20/60 ft)
Weapon: Dagger
On a hit, this dagger absorbs the cries of pain of its target. The energy of the cry is stored in the dagger, which can hold a maximum of 3 cries. On a successful hit, the wielder can choose to release the stored energy. Each stored cry adds +1 thunder damage. When the stored energy is released, the previously smothered cries are audible within a radius of 100 ft. All stored energy is released at once and cannot be divided.
If the capacity of three stored cries is reached, additional cries are no longer suppressed.
