Craven Edge

 is a sentient, thick, onyx, two-handed greatsword once wielded by Sylas Briarwood and then by Grog Strongjaw before being thrown into the pocket dimension of the Dread Emperor. Imbued with dark arcane power, Craven Edge drains strength from the foes it strikes, absorbing their blood into its blade. It may even consume the soul of its wielder, as it did with Grog. As an NPC, Craven Edge is portrayed by Matthew Mercer.

Appearance
Craven Edge is a large, onyx, two-handed greatsword.

Personality
Craven Edge constantly seeks the thrill of battle and the taste of blood on its blade.

Background
While severing Craven Edge's connection to Grog's soul, Pike Trickfoot saw a vision of a nameless man striving for power and wealth, then striking a deal with a dark entity.

The man didn't fully understand the deal he had made, and Pike glimpsed the dark entity punishing him for an unknown action he had made. The dark entity bound the man's soul to the blade now known as Craven Edge, cursing his soul in the process, condemning him to eternal gluttony and an insatiable desire for strength and blood.

Percy gave Craven Edge to Grog, as Grog was the party member best suited to wield a greatsword. When Grog first took hold of it, the sword asked him if he was to be the wielder. Grog was suprised, and immediately asked Craven Edge if it had a female setting or if he could rename it "Bacon". Craven Edge seemed somewhat exasperated by this, but asked Grog to pledge his use of the sword, which Grog did.

Grog first used the sword to intimidate an associate of Riskel Daxio; having the sword out granted him advantage on intimidation checks.

The first person killed on-screen with Craven Edge was Riskel Daxio, who Grog executed by beheading. After taking a life with it, a wave of euphoria washed over Grog.

During the initial attack by the Chroma Conclave on Emon, Grog was the first to attack back, using Craven Edge.

While fighting in a match against Earthbreaker Groon, Grog attempted to switch from using Craven Edge to using his Firebrand Warhammer but found himself unable to resist the sword.

After Pike severed Craven Edge's connection to Grog with a Greater Restoration spell, Keyleth banished the evil sword to the Dread Emperor's realm using Plane Shift. Due to the conflicting statements about the Dread Emperor's realm, it is unclear if Craven Edge is now in the Astral Plane, in a pocket dimension, or somewhere else altogether.

The Legend of Vox Machina
Craven Edge is shown being wielded by Sylas Briarwood against Grog in. As Sylas apparates it from hiding after the political feast with the leadership of Tal'Dorei, he says, "My blade thirsts" as he attacks, and the blade absorbs Grog's blood several times during their battle, seemingly growing in power as Grog weakens.

Features

 * Dark Aura: Grants the wielder advantage on Charisma (Intimidation) checks when unsheathed.
 * Devour the Weak: Whenever Craven Edge damages a living creature, that creature must roll a Constitution saving throw (DC 12).  On a failed save, Craven Edge drains one point from the creature's Strength score and transfers it to the wielder (increasing to a maximum of 25 Strength) until the next short rest or long rest.  Creatures brought to 0 Strength by this feature are slain.
 * Gluttonous Evolution: If Craven Edge devours enough strength from Devour the Weak to bring the wielder to 25 Strength, then the blade shifts form into a larger, jagged blade that seeps shadow.  Until the wielder's next short rest or long rest, all attacks with this sword deal an additional 2d6 necrotic damage.   After the short rest, the attuned creature must make a Constitution saving throw (DC 16) or have the now-hungry weapon, energy spent, devour the wielder's soul, causing instant death.

Secret features
