  • The appearance of the Special Mission "The Crucible"
  • A Ninja Monkey activating one of the Sockets of Power.

The Crucible is a Special Mission for Bloons Tower Defense 5 Deluxe. It is played on the beginner map Bloonhenge. It is unlocked upon reaching Rank 32, rewarding Monkey Dollar1000 upon completion.

In the mission, you must beat 25 special modified rounds on Medium Difficulty, using the two "Sockets of Power." Placing towers on them make them attack dramatically faster as well as having a slightly increased range and Camo detection.

  • Oddly, there is no actual crucible in this mission.
  • The music in this mission is different than playing the track normally.
  • The game does not allow the player to place two towers on one socket of power, despite there being enough room for it.
    • But, if players use a Monkey Engineer with the sentry upgrade, it can spawn on the pillar with it if there is a tiny bit of room for it.
  • Strangely, the sockets of power don't affect Special Agents, Banana Farms, or Monkey Villages.
  • Monkey Villages cannot be placed on the sockets of power due to them being too big to fit. Banana Farms can, but it does nothing to the Farm itself.
  • Regen Farming is possible on this special mission.
  • A Spike Factory in the right socket, and a Glue Gunner in the other one is a deadly force.
  • Placing a Tower in the Crucible with Overclock, M.I.B Call To Arms, Jungle Drums and T2 Specialties can make a Tower attack 5x faster, such that a 1/x Ninja Monkey attack nearly as fast as a Super Monkey.
  • If you put a 4-2 Spike Factory in one of the sockets, it appears that the hatch isn't moving, because of the hypersonic speed it is producing Spiked Mines at.
    • This is only true on Fast Forward, though it still opens and closes very fast.
  • It is possible to beat this mission if you place 2 4-2 ninjas in the power sockets.
  • Portable Lakes don't fit on the sockets.
    • Because of this, it's impossible to place Monkey Buccaneers and Monkey Subs on the sockets of power.
  • A maxed TOTMG/TOTVM on the Socket combined with a 2/4 Village and multiple Overclocks can rapidly annihilate pretty much anything.
