Smite

Smite is an enchantment applied to a sword or axe, increasing the damage dealt to undead mobs (skeletons, zombies, withers, wither skeletons, zombie pigmen, skeleton horses, strays, phantoms, and drowned).

Each level separately adds 2.5 ( × $1 1/4$) extra damage to each hit, to undead mobs only.

Sharpness, Smite, and Bane of Arthropods are mutually exclusive. However, if commands are used to have two or more of these enchantments on the same item, the effects will stack.
