Silent Scythe Of Slaying
Tier 3 Epic abjuration
Casting Time: 1 bonus action
Range: 60 feet
Components: V, S, M (a god’s gravestone)
Duration: 1 minute
You manifest a deadly spectral scythe of pure force within range that lasts for the duration or until you cast this spell again. When you cast the spell, you can attempt a melee spell attack against a target within 15 feet of the weapon. On a hit, the weapon deals force damage equal to 5d10 plus your spellcasting ability modifier. If the weapon scores a critical hit, it rolls damage dice three times instead of twice. Creatures reduced to 0 hit points by this spell are decapitated.
As a bonus action on each of your turns, you can move the weapon up to 60 feet and repeat the attack against a target within 15 feet of it.
