  • The Laboratory is a building where you can upgrade your Troops , Spells and Siege Machines , improving their stats such as damage and hitpoints. The Laboratory is unlocked at Town Hall level 3. The upgrade fee is relevant to the resource used to create said target. Dark Elixir Troops/Spells cost Dark Elixir to upgrade, while all others cost Elixir. Heroes and Pets cannot be upgraded in the Laboratory, instead requiring a free Builder or the Pet House to upgrade respectively. Super Troops cannot be directly upgraded; they are instead upgraded by upgrading the base troop.

  • Heroes and Pets cannot be upgraded in the Laboratory, instead requiring a free Builder or the Pet House to upgrade respectively.
  • Super Troops cannot be directly upgraded; they are instead upgraded by upgrading the base troop.
  • There is no penalty while the Laboratory is upgrading. You can start a new research while the Laboratory is upgrading, and any research continues normally while the Laboratory is upgrading.
  • Normally, only one research project can be done at a time, however the Goblin Researcher , when available, allows a second research project to be done concurrently at the cost of Gems .
  • It is not possible to cancel a research project. However, one can still instantly complete the active one via spending Gems or a relevant Magic Item (a Book of Fighting for Troops and Siege Machines, a Book of Spells for Spells; a Book of Everything can be used for all three). Using a relevant Hammer can skip the upgrade timer and negate any costs. It is also possible to use a Research Potion , Study Soup or Lab Assistant to speed up the timer for a short period of time. Each of these makes the timer tick down faster (at a rate of 24x, 4x or up to 13x respectively), but they only stack additively with each other. If there are two research projects active, the timer speedups apply to both projects.

  • The Laboratories emit a purple (level 1-6), blue (level 7), red (level 8) or yellow (level 9-12) glow from the entrances when upgrading something.
  • The Laboratory cannot upgrade anything the player does not have access to, which may be dependent on the Laboratory itself or said project's associated entity and any other relevant buildings.
  • Different levels of troops will receive graphical changes. However, when you are upgrading something, the laboratory interface will not display the improvements until the upgrade concludes.
  • When a Laboratory upgrade is completed, it is applied immediately to any relevant troops, spells, or Siege Machines.
  • At higher TH levels, Laboratory upgrades are tedious and can take extreme amounts of time. Due to this one should only choose the upgrades affecting whatever that they would prolifically use in the future, and optionally accelerate them with Magic Items. For example, GoWiPe users should focus on Golems, Wizards, P.E.K.K.As, and whatever spells that could help them.
  • If all of your Troops, Spells, and Siege Machines are fully maxed for the current level your Laboratory is at, the text "Research" will not be visible above the Laboratory.
  • When initially constructed, the Laboratory consists of a wooden octagonal structure with multiple door-less entrances. A mass of black tubing covers the center of the Laboratory's roof.
  • At level 2, the Laboratory turns darker and adds a large vat of Elixir mounted on one side, while the roof is reinforced with steel. A dial is on the vat of Elixir, and wires connect it to the roof, near the black tubing.
  • At level 3, the Laboratory's roof adds a large black dome with circular Elixir-colored ports.
  • At level 4, the doorways receive a golden trim.
  • At level 5, a second Identical Elixir vat is added to the left wall. The level 6, the Laboratory receives a faceted crystal sphere on its roof supported by a black iron rod and a helical golden spring. Electricity periodically runs up the surface of the sphere.
  • The level 6, the Laboratory receives a faceted crystal sphere on its roof supported by a black iron rod and a helical golden spring. Electricity periodically runs up the surface of the sphere.
  • At level 7, the crystal sphere is replaced by a huge set of stacked circular gold rings, identical to those found atop the level 7 Hidden Tesla . The elixir vat on the left side of the Laboratory is replaced with a larger one filled with Dark Elixir . The ringed structure on the roof crackles periodically with electricity. The dark color theme indicates that this level is unlocked at Town Hall level 9.
  • At level 8, the circular gold rings are replaced with a vertical tube glowing from the inside. This tube is emblazoned with what appears to be the symbol representing radioactive material, which indicates that the liquid is likely radioactive. The doorposts turn to a dark red color. It seems that fiery red-orange fluid is filling the left chamber. The dial also starts moving back and forth rapidly, showing that the vat may be overflowing. During an upgrade, the vertical tube spews fire. The red color theme indicates that this level is unlocked at Town Hall level 10.
  • At level 9, the stack of rings is re-added to the top of the Laboratory, instead this time the rings are white rather than gold. The doorpost turns from a dark red to white. The red fluid on the left side is changed to yellow. The white and yellow color theme indicates that this level is unlocked at Town Hall level 11.
  • At level 10, the Laboratory takes on a petrol blue color scheme. The stack of rings is now replaced with a giant yellow screw, which twists in and out of the roof when an upgrade is in progress. The dial from level 8 returns and is now larger than before. The fluid vat on the left is now replaced by a metal tube with a cyan glow in the middle. The yellow and blue color scheme indicates that this level is unlocked at Town Hall level 12.
  • At level 11, the Laboratory receives a darker blue color scheme. The roof has a thick band that encases the giant yellow screw, which is now replaced by a tube covered in ice. The doorposts are also covered in ice. The fluid vat on the left is slightly taller and darker. The icy theme and dark blue color indicate that this level is unlocked at Town Hall level 13.
  • At level 12, the ice tube on top of the Laboratory has been replaced with a small, jade pond on top. And it's jade and gold now. The fluid vat on the left becomes slightly shorter, but with gold accents. The fluid changes color from light blue to a gradient purple. Another fluid of Dark Elixir is found on the valve on the left, just above the meter. The jungle theme and green color scheme indicates that this level is unlocked at Town Hall level 14.
  • At level 13, the Laboratory receives a darker indigo color scheme. The roof is covered up, and the pond has been replaced with a purple pyramid-shaped dome with dark purple metal and four hot pink tetrahedron-shaped crystals on top. Below the dome is a ring of metal. On the left side of the building, the fluid vat's frame is now colored a dark purple and the gold accents are gone. The bottom center of the building has received a thicker golden frame and colored a metallic silver on top, and indigo at the bottom. The indigo and gold theme indicates that this level is unlocked at Town Hall level 15.
  • At level 14, the Laboratory receives a dark red and yellow color scheme. The pyramid-shaped dome is replaced with a large, telescope-like device (similar to the one seen on the Star Laboratory ), along with a circular stone ring. Below this ring is another one made of wood. Wooden frames are also added to each of the roof's corners. The fluid vats change as well, with the one on the left now having a light green fluid, while the one on the right resembles a tree trunk with a small leaf growing on it. Thick roots surround the structure, growing around the building. The wires that connect to the fluid vats also change positions, and are no longer connected to the roof. The nature theme and dark red color scheme indicates that this level is unlocked at Town Hall level 16.
  • At level 15, the Laboratory's appearance completely changes. The stone with golden supports at the top is replaced by a stone book with a red bookmark and some symbols, which is held by a platform with golden wings. All the red and light gray parts of the Laboratory are painted gray, except at the middle part of each door post; all the curling vines and leaves are removed. The ring at the roof is now made out of dark stone and gains metal gears on each side, and blue eagle wings on each corner. The vat at the right is now made out of dark stone and iron, replacing the wooden one, the bottom part turns blue with a dark stone base, and the arrow of the dial turns black. At the opposite side, the fluid inside changes to a blue color, and gains metal reinforcements at the leftmost part of the vat. The frame at the bottom part is now made of three layers, with two of these being gold, and a blue one, with each layer decreasing in size as they go lower, until they stop at the stone side support. The stones of the Laboratory appear to be smoother. This level of the Laboratory matches the Town Hall 17 theme.
  • At level 16, TBA.
  • Upgraded troops are now visualized, giving them upgrade differences.
  • Upgraded troops now have pink asterisks that represent their levels.

  • The conductor on top of the Laboratory on levels 6 and 7 depicts the 'lightning gatherer' that is used to raise the dead creatures to life that are often found in horror movies.
  • The pressure gauges on the side Dark Elixir vats are only seen moving on the level 7 and 8 Laboratory, except for when troops/spells go under upgrade. Otherwise, all Laboratory gauges move.
  • The Laboratory is currently the only building that can only be built/upgraded exactly once in every Town Hall level starting from Town Hall 3 to Town Hall 17.
  • Interestingly, in the Home Village's Laboratory, if you have maxed out a troop or spell for your Laboratory level, and click on it, the game tells you, "Level __ Laboratory required". However, in the Builder Base's Star Laboratory, when clicking a maxed out troop for your Star Laboratory level, the game shows you all of the levels and upgrade bonuses, as would normally happen if the troops were not maxed.
  • The Laboratory, Army Camp and the Barracks are the oldest army buildings in the game after its initial release.
  • The phrase: "Harder, better, faster, and stronger!" is a reference to the French dance duo Daft Punk 's widely known song, Harder, Better, Faster, Stronger . In Clash Royale, the Elite Barbarians card uses this phrase in its description. Notably, troops are not made faster, though the Rage Spell and Haste Spell will give higher speed boosts, which justifies the "faster" part.

  • The Laboratory contains four entryways instead of two, they can be seen in the back where the arches for the entryways stand.
  • The total time required to finish all upgrades is theoretically 4 years, 73 days and 18 hours, assuming that the upgrade progress is not influenced by anything (such as Magic Items, time spent to acquire resources and Gems ).
