Echo of a Wail is an intriguing and potent magical item from the Vache Kingdom, said to be crafted by the most skilled enchanters of old. It takes the form of a small, intricately carved orb, made from a mesmerizing crystal that appears to shimmer with a ghostly glow. Within the depths of the orb resides the captured echo of a wailing banshee, a haunting and otherworldly presence that can unleash devastating power upon those who dare to provoke it.

To activate the Echo of a Wail, the possessor must speak the command word, unlocking the dormant power contained within the orb. As the command word is uttered, the orb emits an ethereal resonance, causing the air to vibrate with a haunting energy. This vibration builds up, culminating in a bone-chilling wail that pierces through the surrounding space.

When the Echo of a Wail is activated, it unleashes a wave of sonic force that radiates outward in a 30-foot radius from the orb. This wail of anguish and despair is so powerful that it can rend the life force of lesser beings, causing them to drop to 0 hit points if they fail a DC 13 Constitution saving throw. However, creatures who are constructs or undead remain unaffected by the wail, as their essence is immune to the harrowing effects of this particular magic.

For those who succeed in resisting the full brunt of the wail, they still suffer the lingering effects of its psychic energy. They take 6d6 psychic damage as their minds and souls are assailed by the spectral cry, leaving them dazed and disoriented.

Once the Echo of a Wail has been activated, it requires time to regain its power. It can only be used once per day, and subsequent activation is only possible after the dawn of a new day. This limitation is due to the incredible strain that the wail places on the captured essence within the orb, requiring time for it to recover and gather its ethereal strength once again.

The Echo of a Wail is a highly coveted and feared item, sought after by those who seek a potent weapon capable of dispatching foes swiftly and decisively. Its ability to incapacitate and even slay lesser beings in a single wail makes it a formidable tool in the hands of those who can harness its power. However, it is important to note that the wail's indiscriminate nature requires caution and precision when using the orb, as allies and innocent bystanders can be caught in its devastating radius.

Legends surrounding the Echo of a Wail speak of its creation through a ritual of great complexity and sacrifice. The enchanters of the Vache Kingdom are said to have journeyed to the farthest reaches of the ethereal plane, where they captured the echoes of a banshee's wail and imprisoned them within the crystal orb. The process required intense focus and mastery of ancient arcane arts, as the resonance of the banshee's voice is as deadly as it is haunting.

Possessing the Echo of a Wail grants its bearer a glimpse into the realm of the macabre and the ethereal, a reminder of the raw power that lies within the depths of the magical world. It is a symbol of both awe and trepidation, for its forceful cry carries the weight of sorrow and the finality of death.
