The Blast Barrel is a Hardmode bomb dropped by the Wall of Flesh. When thrown, it will roll across the ground and infinitely pierce enemies it comes into contact with until it hits a wall. Upon colliding with a wall, it will explode into shrapnel and fire shards or bounce again then explode. Shrapnel and fire shards inflict the On Fire! debuff.

Performing a stealth strike with the Blast Barrel will cause the next barrel thrown to bounce off of walls 2 times before exploding on the third wall.

Its best modifier is Flawless.
