The Bomb Arrow is an item used as a weapon and a tool in Adventure Mode, combining the functionality of Bombs with the accuracy of arrows. After it is shot, it has a timer of approximately 4 seconds before it explodes.

To fire a Bomb Arrow, the player must hold a bow in one hand and the Bomb Arrows in the other. Once the player shoots with the bow hand, it will use a Bomb Arrow.
When used as a weapon, the Bomb Arrow will deal 5 full hearts (20 hitpoints) of damage to any mob or player that is standing in point-blank range. Furthermore, it will release smoke particles, and has a knockback effect of 1-2 blocks. You cannot, however, hit a mob with the arrow itself, as it will bounce off.
When used as a tool, the Bomb Arrow can destroy Cracked Cobblestone and Cracked Stone, at a range of up to 3 blocks, depending on where it sticks when fired. It is very useful when a player is required to blow up blocks or mobs that are high up, or at a distance from the player.

Arrow stuck in wall! Gotta wait the 4 seconds for it to explode to see what's hidden behind...
It's gold! Good job, Bomb Arrow!
