Essence Vessels are valuable items found only from Harbinger's loot. They are hefty containers part of the Harken Scythe mod that can collect twice the amount of blood and souls that essence keepers can contain. They are very useful for scooping up the blood and souls that are dropped after killing some of the tougher enemies in the game. They are able to scoop up large portions of boss souls/blood, if the player is willing to risk dying to the boss and losing the vessel.
