Whisper

Whisper is a legendary dagger and one of the Vestiges of Divergence.

Description
Forged with a mercurial metal pulled from the Far Realm, light dances and shifts across this curved blade. Two raven feathers are linked to its pommel as a memento of its former bearer.

Dormant state

 * The wielder gains a +1 bonus to attack and damage rolls made with this weapon.
 * Whenever a creature is struck with a critical hit from Whisper, the target must make a DC 13 Wisdom saving throw or become frightened of the wielder for 1 minute. On a success, they are immune to being frightened by this effect for the next 24 hours.

Awakened state

 * The bonus to attack and damage rolls increases to a +2. Additionally, a target that is hit with this weapon takes an additional 1d6 psychic damage.
 * The DC to resist being frightened from a critical hit increases to 15.

Exalted state

 * The bonus to attack and damage rolls increases to a +3 and the additional damage taken increases to 1d8 psychic damage.
 * The DC to resist being frightened from a critical hit increases to 17.
 * Whenever Whisper is thrown, but before it hits, the wielder can choose to transform into shadow and merge with the blade, teleporting instantly to wherever the blade impacts. If the target is a creature, the wielder emerges adjacent to the target in a space of their choice. If they miss with the attack, the DM determines where the wielder teleports accordingly.

Background
Whisper is said to have been forged from metal pulled from the Far Realm, and was historically at the center of many dark rituals. According to Kamaljiori, around 510 PD, Whisper laid in the Ozmit Sea, near an island of glass, sunken with the ship called the Shrew. It dawned on Scanlan that the description of this island correlates with the Glintshore.

Campaign 1: Vox Machina
Before Vox Machina was able to obtain Whisper in 811 PD, it was recovered by Anna Ripley and given to Kynan Leore to wield. After Ripley's death, Kynan gave the dagger to Vax'ildan.
