The Arrow of Harming (II) applies the Instant Damage II effect upon hitting a target. This effect deals even more immediate damage compared to the standard Instant Damage effect. However, since harming effects heal undead mobs instead of hurting them, the effect of this Arrow of Harming (II) heals creatures like zombies, skeletons, and the Wither.
This Arrow of Harming (II) can be obtained by crafting or, in Bedrock Edition, by using a cauldron. To craft it, players must surround 8 arrows with a Lingering Potion of Harming (II) in a crafting table. Alternatively, it can be made by dipping arrows into a cauldron filled with a Potion of Harming (II).
The Infinity enchantment does not apply to this Arrow of Harming (II), meaning each shot consumes an arrow from the player's inventory.
