Explosives (class)

Explosives are non-magic, ranged weapons that are thrown themselves as ammunition, and cause area of effect damage.

Destructive explosions will also destroy almost any block, exceptions being Dungeon Bricks, Cobalt, Mythril, Adamantite, Hellstone(Before defeating Wall of Flesh), Demon Altars, and any type of Chest (including Barrels and Trash Cans). After the Wall of Flesh has been defeated, they will also destroy hellstone.
