Item: Blade of the Vanishing Echo

Item Type: Rare, Weapon (Shortsword or Rapier), requires attunement

Description: The Blade of the Vanishing Echo is a slender, silvered weapon with an ethereal glow along its edge. Forged in ancient times by an elven shadow-weaver, the blade was designed for assassins and scouts who thrived on agility and stealth. This weapon has a faint hum that grows silent when drawn, as though it absorbs sound itself. Its hilt is wrapped in dark leather, and tiny, intricate runes are etched into the blade that seem to pulse when its powers are activated.

Magical Properties:

Whisper Strike:
When you attack with the Blade of the Vanishing Echo, you may choose to strike silently, leaving no sound to alert enemies. When you take the Attack action, you can activate this ability to make your attack silent, negating all sound for the duration of that attack.
Mechanics: Once per long rest, you can deal an additional 2d6 psychic damage to a target if the attack hits.
Ethereal Vanish:
The wielder can, as a bonus action, vanish into thin air momentarily after striking. Upon successfully hitting a creature with an attack, you may use this ability to instantly teleport up to 30 feet to an unoccupied space you can see.
Mechanics: You can use this ability once per long rest. After teleporting, you gain advantage on your next Stealth check within 1 minute, as the faint sound of your departure fades into an echo.
Echoing Shadow:
When in dim light or darkness, the blade becomes more potent. While wielding the Blade of the Vanishing Echo, you gain advantage on Stealth checks made in low-light conditions, and your speed increases by 10 feet.
Mechanics: This effect only functions in darkness or dim light.

Lore:

The blade is said to have been wielded by a master thief who could slip into the most secure vaults unnoticed, striking with silence and disappearing before guards could react. Over time, the weapon became a coveted item among those who valued both stealth and precision. However, it is rumored to come with a price—those who rely too heavily on its powers may begin hearing faint whispers, urging them to vanish from their own life, forever lost in the shadows.

This rare magic item provides a great mix of combat and stealth capabilities, perfect for rogues, assassins, or anyone who needs to strike from the shadows and disappear.
