Sweeping Edge

Sweeping Edge is a sword enchantment that increases sweep attack damage.

Usage
Sweeping Edge increases the damage dealt to mobs by each hit from a sweep attack by 50%/67%/75% of the sword's attack damage for levels I/II/III.

Damage
The formula for sweep attack damage is:, rounded to the nearest integer. Here, the Attack_Damage is the sword's damage after applying Sharpness, Smite, and Bane of Arthropods. For example, an iron sword enchanted only with Sweeping Edge I deals  damage to each mob hit with a sweep attack. A diamond sword enchanted with Sharpness V and Sweeping Edge III deals  sweep damage. Any sword without Sweeping Edge deals  sweep damage. Extra damage from Smite and Bane of Arthropods is applied against undead mobs and arthropod mobs, respectively.

Higher levels than Sweeping Edge III (obtainable via the use of commands or third party editors) is processed following the formula above and the sweep damage caps beneath 100% of sword's attack damage.
