Source: Tal'Dorei Campaign Setting

Weapon (dagger), legendary (requires attunement)

Forged with a mercurial metal pulled from the Far Realm, light dances and shifts across this curved blade. You have a +1 bonus to attack and damage rolls made with this weapon.

Whenever you strike a creature with a critical hit using Whisper, the target must make a DC 13 Wisdom saving throw or become frightened of you for 1 minute. On a success, they are immune to being frightened by this effect for the next 24 hours.

Awakened. When a character awakens Whisper, apply the following changes to the item’s traits:

  • Increase the bonus to attack and damage to a +2. Additionally, when you hit a target with this weapon, the target takes an additional 1d6 psychic damage.
  • Increase the DC to resist being frightened from a critical hit to 15.

Exalted. When a character exalts Whisper, apply the following changes to the item’s traits:

  • Increase the bonus to attack and damage to a +3, and increase the additional damage taken to 1d8 psychic damage.
  • Increase the DC to resist being frightened from a critical hit to 17.
  • Whenever Whisper is thrown but before it hits, you can choose to transform into shadow and merge with the blade, teleporting instantly to wherever the blade impacts. If the target is a creature, you emerge adjacent to the target in a space of your choice. If you miss with the attack, the DM determines where you teleport accordingly.
