The Death's Scythe is a sword-type meleeweapon added in the Return to Castlevania DLC. Forces the spirit of enemies you killed to help you, summoning them as allies. They will target and explode on near enemies, dealing a Critical Hit.
"Enemies killed by ghosts become ghosts themselves"
Synergies
This weapon can benefit from the Instinct of the Master of Arms mutation, as the ghosts it summons deal critical damage.
The ghosts summoned by this weapon are considered a ranged attack and are therefore affected by ranged mutations such as Point Blank.
Notes
Most enemies spawn ghosts, there are however few exceptions like Myopic Crows and Protector.
Like all weapons added in Return to Castlevania DLC expansion, Death's Scythe is based on the weapon from the Castlevania series. In this case, it is known under the same name.
Visually, no known version of Death's Scythe resembles one from Dead Cells except for the crude design, resembling his scythe in his second phase in aria of sorrow. However, half of it looks similar to one from Castlevania: Dawn of Sorrow.
