This guide will let you know how to make Scarab Bomb in Terraria 1.4. It will provide you with the easiest mining.
The Scarab Bomb is a sticky thrown explosive used for mining large shafts.

Once stuck to a block, it will explode after a short delay, creating a 21 block long and three blocks wide shaft facing directly away from the player.

It will explode in the direction the player is facing.
Recipe:
The Ingredients of the Scarab Bomb are “Bomb” and “Sturdy Fossil”.
The crafting station is ‘by hand’. You can obtain Sturdy fossils by putting desert fossils on the extractinator.
