Knockback

Knockback is a basic mechanic in Terraria, whereby players and enemies are repelled in the opposite direction of an attack. Most weapons and environment objects that cause damage also cause knockback, to varying degrees. Some enemies are immune to knockback, particularly Bosses and other enemies that travel through blocks, like Worms and Man Eater. Some enemies also have varying degrees of knockback resistance.

Equipping any Shield will grant the player knockback immunity.

The most player-inflicted knockback comes from the Golem Fist, which has a knockback value of 12. This is followed immediately by the Thorns Potion with a knockback value of 10, then the Paladin's Hammer with a knockback value of 9, then the Enchanted Boomerang, Flamarang, Thorn Chakram, Light Disc, Hellfire Arrow, Grenade and Breaker Blade, which all have knockback values of 8 each.

Various modifiers, and the Titan Glove accessory, can increase player-inflicted knockback.
