Dark Elixir Drill



"Our Alchemists have finally figured a way to extract pure Dark Elixir, the rarest form of the magical substance."


 * 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 space.
 * The Dark Elixir Drill is unlocked at Town Hall level 8, though the Storage is unlocked at Town Hall level 7. Until the drill is constructed, Dark Elixir can only be obtained by raiding.
 * 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 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 is rather 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 80% full.
 * You can temporarily boost its production with Gems. Spending 40 Gems will double the Drill's production for the next 6 hours.


 * 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 stone, and the tops of the wooden pillars suspending the auger receive gold plating.
 * At level 3, much of the surface of the top of the drill and frame is covered in gold plating; at level 4 the two footings trade their smooth stone for dark iron.
 * The level 5 and 6 Drills add additional goldwork, with spiked armor plating also appearing on the footings of the level 6 Drill.


 * The "Catch Up Point" is the time at which the newly upgraded drill has equaled the total production of the drill had it not been upgraded - this does not consider recovering the cost of the other resource required to perform the upgrade. For example, when going from Level 2 to Level 3, it would take 6 days to make up the Dark Elixir that would have been produced during the upgrade time.
