"Elixir is pumped from the Ley Lines coursing underneath your village. Upgrade your Elixir Collectors to maximize elixir production."
The Elixir Collector collects Elixir from an unlimited underground reserve (a.k.a Ley Lines) and stores it until collected by the player and placed into an Elixir Storage. When the collector is full, production will be stopped until it is collected (or raided by an enemy player).
The production rate and capacity depends on the level of the Elixir Collector. Players can get an idea of how much Elixir the collector is storing by how full the tank appears.
The Elixir Collector takes up a 3x3 tile space.
Tapping on the collect icon collects all Elixir from all Elixir Collectors.
When you choose to upgrade an Elixir Collector, it will automatically collect any uncollected Elixir. Note that if your Elixir Storages are full at that time, the uncollected Elixir will be lost! During the upgrade the collector temporarily stops producing Elixir.
Once the Elixir Collector is level 5, you can temporarily boost its production with Gems or a Resource Potion. Spending Gems will double the Collector's production for one day, while using a Resource Potion will double all Home Village resource collectors' production rate for one day. When you click to boost the Elixir Collector, a clock appears for a few seconds.
Level 1-4 Elixir Collectors cannot be boosted with Gems, but can still be boosted using a Resource Potion. However, you can only use the potion if you have a collector that can be boosted with Gems (either a level 5 or higher Gold Mine or Elixir Collector, or any level of Dark Elixir Drill).
If you upgrade the Elixir Collector while a boost is active, the boost will end prematurely, even if the upgrade is later cancelled (or completes) at a time where the boost would have been active.
It is a good idea to put your Elixir Collectors outside of your Walls, so they can act as a distraction to units such as Barbarians and Archers.
Attackers can steal up to 50% of the uncollected Elixir in the collectors. Having too many uncollected resources will make you a more attractive target.
High Leveled Elixir Collectors can stall certain troops or parts of the army for quite a while. Use it to stall and stifle funnels and other important things in attacks that need to be quickly and properly executed.
If an Elixir Collector is destroyed in an attack while it is being upgraded, no Elixir will be lost as the collector is empty during this time.
Pay careful attention to the location of Elixir Collectors when planning your attack, as Elixir Collectors are usually only marginally protected and can be quite lucrative, especially at high levels. Many times a single Archer can be placed in such a way that it can destroy an Elixir Collector while standing clear of any defenses. Alternatively, if you are Town Hall 11 or higher, a single Sneaky Goblin can often destroy an Elixir Collector without getting detected.
If you see a round number of Elixir in a raid, it is most likely going to be in the Elixir Collectors rather than in the Elixir Storages (example 90,000). Although round numbers can occur in Elixir Storages, they happen much more often when Elixir Storages have been emptied by a previous raid and the resultant shield has allowed the Elixir Collectors to completely fill up.
When raiding for Elixir, you can tell if the Elixir Collector is full or not by looking at how filled the tank is. Due to the large tank visuals, it is easier to tell if Elixir Collectors are full than Gold Mines, so use that fact to your advantage even when farming Gold (Elixir Collectors will fill at the same rate as same-level Gold Mines).
Elixir Collectors undergo significant visual changes at levels 5, 7, 8, 10 and 14.
When initially constructed, the Elixir Collector consists of a large, transparent cylindrical vat standing vertically on a wooden base. A long, narrow metal tube extends from the top of the vat and bends down to a small brass pump with shutoff valve embedded in the ground. Elixir periodically bubbles out of the air vent on the top of the vat.
At level 2, a second narrow metal tube appears, and the brass pump grows larger. Additional tubes are added at levels 3 and 4, with the pump also increasing in size.
At level 5, the four narrow metal tubes are replaced with one much larger diameter tube, and the brass pump and shutoff valve moves to the opposite side of the collector. The shutoff valves' wheel grows much larger, too. A flat metal skirt appears around the base of the collector as well.
At level 6, a second, smaller metal tube appears, connecting to a smaller (valve-less) pump on the opposite side of the collector. The level 7 Elixir Collector adds another smaller tube.
At level 8, the two smaller tubes on the left side of the collector are replaced with a single large-diameter tube, which joins the original tube at the top of the collector. The second pump on the left side of the collector receives a small shutoff valve wheel as well.
At level 9, the wooden cap on the cylindrical vat is replaced with brass. The collector gets a third large tube coming from the back and a brass reinforcing bar appears on the front of the vat.
At level 10, the top of the collector receives a large brass junction where all the tubing enters. Two additional large-diameter tubes are added as well, for a total of five. Shutoff valves are visible on three of the tubes as well as on the top of the junction. Additional reinforcing bars appear on the front of the vat, along with more organized/neat tube placement.
At level 11, the shutoff valve on the top of the vat disappears, replaced by still more tubing. The reinforcing bars are replaced with wide brass reinforcing plates that nearly cover the entire vat. The shutoff valves change into a gear like shape.
At level 12, the tubes on the sides and back become larger, and spikes are added to the top. The small pipe in front of the collector is moved to the back. On the top, there are now three tubes instead of two, and more bolts are added to the top and the front.
At level 13, the 3 tubes merge into 1 big tube and the 3 thinner front brass supports are abandoned as they merge into 2 very thick brass supports. The thin exhaust pipe at the top is removed. The skirt at the bottom loses its golden bolts and becomes thicker. The shutoff wheels become black and smaller.
At level 14, the four tubes at the bottom are replaced with a single, larger tube on the left side of the collector. The tube at the top becomes larger and no longer sports a golden ring. The golden brass supports on the front are completely removed. The metal skirt on the bottom is replaced with a rough stone skirt. An Elixir exhaust system appears on the right side as well, pumping Elixir into the atmosphere.

The Elixir Collector is one of the 8 buildings that you are automatically set with at the beginning of the game..
Although directly selecting an Elixir Collector with an Elixir bubble above it automatically collects any resources it has stored, there is a way to check how much 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 Elixir Collector and choose the "Info" option to display the amount of Elixir gathered by the collector to that point.
The Elixir Collector is the only resource-related building to be a card in Clash Royale.
The Elixir Storage also appears in Clash Royale, but only in a special game mode (it does not appear otherwise).
A bug introduced in July of 2018 caused the Elixir Collector to look the same on level 1 and level 2, making it the first building that doesn't always change its appearance after it is upgraded. This was fixed in the Winter 2019 update.
As of the May 2016 update, collecting Elixir has a new sound effect. Prior to this update, collecting Elixir sounded like this.

Gold Pass modifiers
Input Gold Pass boost to modify the statistics in the tables below accordingly
* The Catch-Up Point is the time at which the newly upgraded Elixir Collector has equaled the total production of the collector had it not been upgraded - this does not consider recovering the cost of the Gold required to perform the upgrade.
Caveat: The Catch-Up Point calculation assumes that the player collects all resources from the Elixir Collector 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. Or, in easier to understand terms, the catch-up point is the amount of time it would take to get the resources it would have collected if it wasn't being upgraded.
