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 the Worms and Man Eater. The Cobalt Shield grants the player knockback immunity. Knockback has the same effect as the Grappling Hook, which can be used to reach the Hermes Boots speed instantly.

The most player-induced knockback can currently be inflicted using the Thorns Potion, which has a knockback value of 10. This is followed immediately by the Enchanted Boomerang, Thorn Chakram, Flamarang, Hellfire Arrow, and Grenade, which all have a knockback value of 8.
