• Summary
  • The Dark Elixir Drill collects Dark Elixir from an unlimited underground reserve, and stores it until it is collected by the player and placed into a Dark Elixir Storage. When the drill is full, production will be stopped until it is collected.
  • Attackers can steal up to 75% of the uncollected Dark Elixir in the drill. Having too many uncollected resources will make players a more attractive target.
  • The Dark Elixir Drill takes up a 3x3 tile space.
  • After the 2014 Christmas update, the Dark Elixir Drill is unlocked at Town Hall level 7, along with the Storage. The second and third drills are now unlocked at Town Halls 8 and 9, respectively. Until the drill is constructed, Dark Elixir can only be obtained by raiding, participating in Clan Wars, collecting Dark Tombstones from dead Dark Elixir Troops, and/or using Gems.
  • When you choose to upgrade a Dark Elixir Drill, it will automatically collect any uncollected Dark Elixir. Note that if your Dark Elixir Storage is full at that time, the uncollected Dark Elixir will be lost. During the upgrade the drill temporarily stops producing Dark Elixir; if it is destroyed in an attack while the upgrade is in progress, no resources will be lost to the attacker, as the drill is empty.
  • It can be difficult to see without zooming in, but you can visually tell approximately how much Dark Elixir a Dark Elixir Drill currently contains by looking at the glass box on the top rear portion of the drill. An empty (clear) box means the Drill is less than 20% full, while a full (black) box means the Drill is at least 60% full.
  • You can temporarily boost its production with Gems. Spending Gems will double the Drill's production rate for 1 day.
  • When raiding, the easiest way to tell the difference between the various levels of enemy Drills is to look at the Drill's footings. Unlike the top of the Drill, there is a very recognizable difference between the footings of all six levels.

• Upgrade Differences
  • Dark Elixir Drills undergo a significant visual change at level 3.
  • When initially constructed, the Dark Elixir Drill consists of a huge helical auger, suspended from a sturdy wooden frame with mortared stone footings. A deep hole, framed with wood, sits under the auger.
  • At level 2, the Drill's footings become smooth white stone, and the tops of the wooden pillars suspending the auger receive plating. Three hexagonal shapes are also added to the top of the drill.
  • At level 3, a large part of the drill's top surface and frame become covered in gold plating, and the footings gain a grey metal band.
  • At level 4, the footings trade their smooth stone and grey plate for smooth dark iron.
  • At level 5, the mining hole increases in size, and the footings acquire a gold band.
  • At level 6, the gold cover on the footings is replaced by a spiked gold plate. The auger itself turns to gold as well.
  • At level 7, the spikes on the bottom become more scarce and spread out while the bolts on the top change position slightly.
  • At level 8, the spikes on the bottom are coated with dark metal and protrude from a trapezoidal prism. The top and the sides of the drill are now dark metal as well. The "shoulders" are slightly bigger and the mining hole is now framed with dark bricks.

• Trivia
  • The level 3 Dark Elixir Drill will continue to produce over the course of a full 12-hour shield (assuming it was empty when the shield is obtained). A level 4 Dark Elixir Drill will continue to produce over the course of a full 14-hour shield. A level 5 Dark Elixir Drill will continue to produce over the course of a full 16-hour shield.
  • When you activate the boost for a Dark Elixir Drill, a clock will appear over the drill for a few seconds.
  • Although directly selecting a Dark Elixir Drill with a Dark Elixir bubble above it automatically collects any resources it has stored, there is a way to check how much Dark Elixir has been stored without collecting it. This can be done by moving any other building to an invalid spot on your map (e.g., off the edge of your map, or fully or partially occupied by an obstacle, decoration, or another building) and releasing it while its surrounding square has turned red. Then select the desired Dark Elixir Drill and choose the "Info" option to display the amount of Dark Elixir gathered by the drill to that point.

* The Catch-Up Point is the time at which the newly upgraded Dark Elixir Drill has equaled the total production of the drill had it not been upgraded - this does not consider recovering the cost of the Elixir required to perform the upgrade.

Caveat: The Catch-Up Point calculation assumes that the player collects all resources from the Dark Elixir Drill without allowing it to reach its storage capacity, as resource production ceases at that point. This is more of a concern at lower levels where the capacity is limited and Time to Fill is relatively short. If the player is unable to regularly collect and achieve the full potential of the collector, the Catch-Up Point is actually shorter, and performing the upgrade becomes more advantageous.
