This article is about the explosive block. For the explosives weapon class, see Explosives (class).
Both kinds of Explosives traps.

Explosives are a placeable, consumable mechanism that can be triggered using wiring. Triggering them causes a large, circular explosion that covers a radius of ten tiles[1] (up to 314 blocks total), destroying most placed blocks and items (except for explosion-proof items), and inflicting a knockback of 10 (Extremely strong). The explosion deals 1000 / 2000 / 3000 base damage to players (500 base damage to NPCs, enemies, and critters).[2] Therefore, they can kill or severely damage even players with late-game gear.

Explosives can spawn naturally as traps wired to Pressure Plates, or wired to Detonators(Desktop, Console and Mobile versions) next to a vein of ores can be found in the Underground and Cavern layer.

  • Explosives cannot be placed on top of each other. However, other blocks can be placed on them, and more Explosives can be placed on those.
  • Due to invincibility frame, multiple Explosives triggered at once can only deal damage to the same enemy once.
  • (Old-gen console and 3DS versions) If a player is killed by Explosives detonated by them, they will not lose their coins.
  • An Explosives block within the blast radius of another will not be activated, therefore chain reactions cannot be created with Explosives. Rather, the second Explosives will simply drop, as with other blocks.
  • Explosives which have been actuated will still explode when triggered.
  • Explosives, despite their name and crafting recipe, do not fulfill the Demolitionist's requirement to move in.


  • The death message that appears when the player is killed by naturally spawned explosives will read that they were killed by their own explosives.


  • Desktop Dying to Explosives should now handle mass item drops more efficiently and will preserve item drops in Mediumcore.
  • Desktop Fixed a bug where Explosives counted as PvP damage, resulting in coins not dropping when the player was killed by them.
