Knockback

Knockback is an enchantment applied to swords and spears that increases melee knockback.

Knockback can be obtained from enchanting tables, drops from mobs that have spawned in a raid,‌[Bedrock Edition only] books obtained by fishing, monster room chests, librarian villagers, and non-village structure loot.

Knockback increases horizontal melee knockback by 2.586 blocks per level. The base knockback of attacks without the enchantment and without doing a sprint-knockback attack is 1.552 blocks, causing an attack with Knockback II to deal 6.724 blocks of knockback.​[more information needed] Knockback also increases vertical melee knockback from 0.8125 blocks to 1 block, regardless of the level of enchantment. Sword sweep attacks are affected by the Knockback enchantment. The increased knockback from this enchantment stacks with sprint-knockback attacks.
