Like the X-Bow, Inferno Tower and the Scattershot, it needs to be loaded to work. Loading is free and takes place automatically after the player logs in; the Eagle Artillery will eventually be depleted of ammo and become unloaded if it is not loaded by the player.
During a defense, the Eagle Artillery remains dormant at the start and activates only after a large number of housing spaces worth of troops have been deployed. The Eagle Artillery will light its eyes at first after 150 housing spaces worth of troops and will activate at 180 housing spaces worth of troops for levels 1 and 2. The housing space requirement to activate the Eagle Artillery increases to 200 at level 3.
When the Eagle Artillery is ready to fire, the eagle head slides down to the front of the structure to reveal a hexagon-shaped barrel with bright light pulsing around it.
Heroes and spells that have been deployed regardless of level, will count towards the housing space needed to activate the Artillery. Each hero is worth 25 troop housing spaces, and each spell housing space is worth 5 troop housing spaces.
Each Siege Machine counts as 1 troop housing space towards this number. Clan Castle troops do not count towards this number, but any reinforcement spells count the normal amount.
Pets, regardless of level, do not add any housing spaces towards the activation.
Activating the Archer Queen's or Barbarian King's ability will not add more troop spaces. Units that spawn sub-troops, whether upon death such as the Golem, or periodically such as the Witch when spawning Skeletons, do not add more spaces. Dropping a Skeleton Spell only adds the spell's equivalent worth of 5 troop housing spaces, the Skeletons don't add more spaces; similarly dropping a Clone Spell only adds the spell's equivalent worth of 15 troop housing spaces, the cloned troops don't add more spaces.
It fires a volley of three successive shots at regular 10-second intervals. Each shot is able to deal devastating splash damage (in a very small radius) to the unit it targeted with extremely small splash damage (in a big radius and knocks back smaller troops) to the units near its target.
The shockwave damage also affects the main target, so effectively the Eagle Artillery does slightly more than its stated damage per hit to its main target. The total damage per hit onto the main target is simply the sum of the damage per hit and the shockwave damage.
The Eagle Artillery targets according to a "heat map" or "hitpoint map". In other words, it targets the area with the largest density of hitpoints.
The Eagle Artillery places a bright yellow mark on the unit it's targeting, and the quicker the moving spots move, the closer the shots are. These markers lock onto units and will follow them as they move, unless they move into the Eagle Artillery's blind spot or out of range, in which case the targeting marker and shots land at the edge of the Artillery's range.
Unlike other defenses, the Eagle Artillery recalculates its targets each volley.
Place this defense in a place where its blind spot is covered, like a Mortar. Remember that it will only activate and begin to attack when a certain amount of troops are deployed, so keep it near the middle. This is so that by the time enemy troops start to enter your base, it will be in action.
Try to centralize the Eagle Artillery so troops cannot get to it easily as it does more damage. In an anti three-star base, centralizing the Eagle Artillery is more important than protecting the Town Hall.
Keep it away from other very important defenses such as the enemy Queen and Clan Castle, as this can allow for easy value as by TH11 players have ways to send parts of their army inside the base.
Eagle Artillery is best supported by an Air Defense, as the Air Defense destroys air troops while the Eagle Artillery picks off the ground troops. For extra support, you can place a Wizard Tower to cover the blind spot.
While centralizing it is important to offset the Eagle Artillery so it can keep firing while the troops are in the core. This is even more effective because a ton of troops tend to be clumped in the core.
Use Freeze Spells to stop the Eagle Artillery from shooting your units. You should freeze it when it is about to shoot, not during its 10-second intervals, nor after the missiles are already in the sky. If done correctly, it can minimize the damage, and to force the Eagle Artillery to use more time to fire.
For Heroes, if the Eagle Artillery has been activated, it will most likely lock onto the Barbarian King, as he has much more health than other heroes. If the Barbarian King is not deployed or has been defeated, it will then lock onto the Royal Champion, since she has the second highest health. It will lock on the Archer Queen or Grand Warden if the Royal Champion or Barbarian King is not in the action. If there is a Golem or a lot of troops are close together, then it will attack the Golem or the troops. Sometimes it might attack your Grand Warden or Archer Queen even if the other two Heroes are still on the battlefield, however this is unlikely.
The Grand Warden's ability can be used to tank one volley of shots from the Eagle Artillery for any units inside his proximity. Use this when units are going into the core of the base.
You can use the Jump Spell to have melee troops destroy the Eagle Artillery quickly.
Don’t place all your troops in one area. Eagle Artilleries still do have splash damage and will take out any hordes of Balloons or Minions.
Bat Spells are effective against the Eagle Artillery. They will target the Eagle Artillery and fly over any Walls blocking its way. A swarm of them will enter the blind spot and wreck havoc against it. Be wary of Wizard Towers and Inferno Towers (in multi-target mode) placed near the Eagle Artillery, else the bats die off possibly leaving it undamaged.
When the Eagle Artillery is in the process of locking onto the Archer Queen, you can use her ability to prevent it from locking on and force it to spend time to retarget. However, if the Eagle has already started to fire, using the ability will not prevent the shots from hitting your Queen for massive damage.
Placing 3 Golems together will very likely cause the Eagle Artillery to lock onto the Golems, allowing the other troops to attack.
The Eagle Artillery undergo significant visual changes at all levels.
At level 1, the Eagle Artillery appears to be an eagle head on an iron podium, with hard iron feather-like decorations near where the shoulders would be, connected with chains to the front side plate. It appears to be made out of iron, rock, and gold. The top of the base has red carpet, on the corner it has some support with a spike protruding and the side has metal plates that bolted down with brass pentagonal bolts. When activated the eagle head slides forward with its eyes light up and the artillery behind the head slides up, which makes one of the spikes on the artillery visible.
At level 2, the ring and plate surrounding the shoulders, the chains, around the red carpet, the side plates of the base, the spike from the corner support, and the metal rim by the muzzle of the artillery changes from iron to gold. The side plates now have spikes instead of pentagonal bolts and the corner supports become larger.
At level 3, the Eagle Artillery is now encased in metal plating that surrounds the perimeter of the base, the top of the base now have dark blue carpet, the corner support has been replaced by extra tall and thick plating with pentagonal bolt, and the side plates now connects to the carpet covering only the first layer of the base. The metal used on the base has a slightly bluish hue. The chains are replaced with a black wire connecting to the front which is now an electric coil. The parts between the golden ring and plate on the shoulders are now replaced with black metal and the wings themselves gain a golden tip.
At level 4, the "feathers" of the eagle head become longer, and a blue arrow shape is added to the top of the head. The head of the eagle becomes a darker grey. The gold plate underneath the head becomes smaller, and the carpet underneath becomes solid and light blue. The bolt-like plate on the shoulder changes to a pale blue color and pale blue tubes connect from the shoulder plate to the front. The corner supports become larger and now have large spikes. Purple is added to the bottom of the base and black metal pillars appear on each side of the podium.
At level 5, the base of the Eagle Artillery changes shape completely and has gold trims on each side. The middle of each side now has a waterfall with flowing green water. The pipes connecting the wings to the base now become green with vines wrapped around them, and the connection to the base becomes gold. The blue around the wing becomes gold too, alongside both of the entire wings.

The Eagle Artillery is the only defense in the Home Village whose in-game statistics use "damage per hit" rather than "damage per second" (several defenses in the Builder Base, such as the Double Cannon, as well as the geared-up Cannon and Mortar, show both "damage per hit" and "damage per second"). This may be due to the fact that the Eagle Artillery fires in volleys.
However, many players think that the Mortar should be changed to share this property.
The Eagle Artillery is the only defense in the Home Village where only one can be built, assuming the Giga Weapons do not count toward this.
The Eagle Artillery uses the Cannon's sound effect when tapped which is not unique, but has its unique sound effect when placed.
It also has its own unique sound effect as well, different from the actual shooting sounds.
The Eagle Artillery is the most expensive defense in the game, at 20,000,000 gold.
If the Eagle Artillery is destroyed before targeting, it will still make a "target" sound.
When activated, it makes a sound that sounds like an eagle’s cry.
The Eagle Artillery is the defense with the largest range in the game and the biggest blind spot in Home Village.
