An Empty Plot of Land

Specialty Buildings (Specialist Buildings on mobile) are ways to specialise in any one tower type in Bloons TD 5. The buildings buff a tower in certain ways but it also increases the cost of another tower and its upgrades by 5%. A plot of land must be purchased for Monkey Dollar250. Then, a Specialty Building can be build on top of it. After that, every Building can be upgraded up to 3 times. In BTD5 Flash and BTD5 Deluxe, it can only be upgraded 2 times.

While all Specialty Buildings can be bought, only one can be active at a time. Purchased Specialty Buildings can be activated or deactivated by clicking on the "Activate" or "Deactivate" button appearing over the Specialty Buildings "shop".

The first upgrade reduces the price by 5%, while the second one mostly increases the fire rate of the tower by 10% (second upgrade generally costs the same as the first). The third and fourth upgrade is special and different for each tower. It also costs more than the first two upgrades.

Specialty Buildings

In Mobile and Steam, the Specialty Buildings will also visually appear different when upgraded further. These visual changes to the Specialty Buildings have no impact on the gameplay, only an indicator for ranks of the buildings.

  • Specialty Buildings occasionally suffer a bug, where instead of reducing the cost, it raises the cost instead. This happens only with tier 3 and 4 upgrades, and it is very likely to occur with Specialty Buildings of low-power towers, such as Dart Training Facility and Rifle Range.
  • Monkey Villages' effects can stack with Specialty Buildings.
    • Jungle Drums Monkey Villages are very helpful combinations with specialty buildings especially if maxed out, providing an overall 15% discount and a 25% increase in firerate for the particular tower.
      • 40% if the player has a Level 8 Attack Speed in Monkey Lab, and a whopping 51% with Level 13 Attack Speed (Bloons TD 5 Mobile and Steam).
  • There are no Specialty Buildings for the Monkey Village or Banana Farm, nor Road Spikes or Pineapples.
  • The first upgrade reduces the cost of the tower and its upgrades.
  • The second upgrade is the same cost as the initial cost of the building
  • The third and most powerful upgrade costs more for everything except the Super Monkey Lair, where all the upgrades cost the same.
  • The 4th tier upgrades for Speciality Buildings are only available in Bloons TD 5 Mobile/Steam.
    • Some of the 4th tier upgrades are actually premium upgrades on BTD 5 Flash(Example: Double Ranga and Dreadnought)
  • The increase in price for some of the Bloons TD 5 Mobile Specialty Buildings have additional effects due to more powerful Tier 3 and 4 upgrades.
  • Specialty Buildings will be changed to the same building that was saved in a game if attempting to load a saved game no matter what building was activated at the time of the load (unless in the mobile version).
