A sword that exists in the 4th dimension. So powerful it can alter reality itself

4D Sword is an Epic weapon in Bloons Adventure Time TD. It has a special property to slow bloons (including MOABs) on contact and completely destroy them with 5% chance, with a cooldown of 7 seconds. It can only be equipped by Finn, Warrior Bubblegum and Dungeon Finn.


It is fully black, opaque long sword with white lines that resembles a sword from the 4th dimension.

Special Properties[]

Slow bloons (Including MOABs) on contact with a 5% chance to insta-kill them completely. Cannot affect BADs.

This insta-kill ability has a cooldown time for 7 seconds each time a bloon is destroyed and can affect bloons up to ZOMGs.

Trinkets (such as Missile) can no longer acquire the sword insta-kill effect when equipped by the same character after the 1.6.2 update.


  • This sword is very useful for (potentially yet quickly) taking down MOAB-class bloons that escape your defenses or are just released from the BAD, as its slowing effect makes bloons stay in the character's range for longer, buying them more time to use the insta-kill effect against stronger bloons.
  • Use it at the end of short tracks where characters only have a short amount of time to damage bloons before they reach the exit.
  • Note that MOABs deleted by its effect will have other potential drops, including TCW's loot drops, deleted along with them.

Version History[]
