The Rocket is a Rare card that is unlocked from the Builder's Workshop (Arena 5). It is an area damage spell with a small radius that inflicts extremely high damage and knockback on impact. This spell takes the form of a large missile launched from the King's Tower. A Rocket card costs 6 Elixir to deploy.

## Strategy

* The Rocket has the highest damage per elixir against Crown Towers, and is most effectively used offensively to finish off weakened ones, making it a great endgame spell to bring. The spell should be aimed at the bottom corner of the Crown Tower closest to the player's own King's Tower to minimize the lengthy travel time of the Rocket.
* As a general rule of thumb, if there are or will be units around the Rocket's intended target, aim to hit them all at once. It is not worth it if the primary target isn't hit, so don't switch targets from the intended one unless a more important target is deployed.
* It can take out medium health troops such as the Musketeer, Wizard or the Witch. However, since this is a negative Elixir trade, it is better to wait and see if the medium health unit is placed close to a Crown Tower or used with another unit, which would allow the Rocket user to get more value. Otherwise, using regular units along with the Princess Tower's damage or even other cards is more efficient.
* It can completely counter Elite Barbarians for a neutral Elixir trade. However, due to their fast move speed making it difficult to aim, this is a somewhat risky play unless this can be compensated for.
* The Rocket can also take out an equally leveled Mini P.E.K.K.A. While this is a negative Elixir trade, it might worth since he almost always comes with low cost support troops that could balance the cost.
* It is not recommended to use the Rocket against swarms of low hitpoint troops due to its small radius unless the player can get more value by hitting something else. Using spells like Arrows or Zap are usually better, but Rocket could be played in desperate circumstances to destroy a Minion Horde or Skeleton Army.
* Use the Rocket to weaken or destroy buildings, such as the Barbarian Hut, to hinder the opponent and also make way for a push. Rocketing the Barbarian Hut also yields an Elixir profit.
	+ If not timed properly the Barbarian Hut will still spawn 2 out of 5 waves of Barbarians, but if timed just right, the Rocket will kill off an additional wave. Launch the Rocket when the first Barbarian has traveled 15 tiles. If they plant their hut in the back, launch the Rocket when the first Barbarian crosses the bridge. If it is not placed in the back, keep in mind that the Barbarian Hut takes 12.5 seconds to spawn a pair of Barbarians. Keep track of the time and send the Rocket after 7 to 9 seconds, depending on where it is placed. Memorizing these timings is important if the player is consistently facing spawner decks.
	+ The player can aim the Rocket so that it lands on the very edge of the hut, damaging both the hut and nearby Barbarians. Hitting both the hut and Barbarians requires precise timing, as the explosion radius is fairly small.
	+ A Rocket can deny all Elixir from being generated by an Elixir Collector up to 4 levels higher than it, though the pump will still generate one Elixir when it is destroyed. If the Elixir Collector is placed behind a Princess Tower, the user can also deal decent damage to the Tower. Most opponents will adapt to this and start placing their Elixir Collector in front of their King Tower, to prevent you from hitting both the Princess Tower and the Elixir Collector.
	+ The Rocket is a fairly reliable counter to X-Bow. The Rocket will heavily damage it, or completely destroy it if the Rocket is at least 1 higher level than the X-Bow. Since it deals high area damage, it can also eliminate any support units played alongside the X-Bow, giving the player an Elixir advantage. However, an equivalently-leveled X-Bow will still deal around 15% of the player's Princess Tower's health so using a cheap unit to distract it for a bit longer is recommended.
	+ Even though the Rocket is one of the best ways to destroy buildings, in most cases it is a negative Elixir trade. Therefore, it is important to know when it is a good time to fire a Rocket. This also applies to troops. If you are only hitting 1 or 2 troops, it usually results in a negative Elixir trade. If you purely want to destroy just buildings, you can consider bringing Earthquake, which costs half as much.
* The Rocket is difficult to aim and target at fast troops, as the spell has a considerable cast time and small damage radius, but can be overcome by an experienced player.
	+ Because of this, Rocket pairs very nicely with Tornado. The Tornado will drag most, if not all, desired targets into the Rocket's blast radius, allowing for the annihilating of large groups of medium sized troops while also heavily damaging larger ones. Make sure that the Rocket is launched *before* the Tornado, and the Tornado's center overlaps with the Rocket's radius. Remember that certain units resist a Tornado more than others, including charging units such as Prince and heavy units such as Giant, so this tactic may not always work. It also costs a hefty 9 Elixir, leaving you very defenseless, though it may be worth it if you are against a large push as it will nuke the push completely.
		- Aim the Rocket considerably in front of the target or at the shadow in order to hit them properly.
		- The player can also use the Lightning as an alternative, as it has a larger range and can hit up to three targets, along with doing instant damage. The tradeoff is that Lightning does considerably less damage, can *only* hit a maximum of three targets, already has a wide radius, and targets based on hitpoints.
* If the opponent uses a Rocket, depending on what they hit, it may be a good idea to send an attack down either lane as long as it is not too expensive, due to the fact that they will have to replenish up from four Elixir unless they have Elixir Collectors down.
* If the opponent places a Sparky, a Rocket with the same level can destroy it for a neutral Elixir trade. If they placed their Sparky in the back, the Rocket can also deal decent damage to their Crown Tower.
* This can be used as an alternative to the powerful Fireball and Zap combination, as that combo can only defeat a minimum of 9 cards of equivalent level that a lone Fireball cannot (Hunter, Fisherman, Witch, Musketeer, Wizard, Royal Hogs, Three Musketeers, Electro Wizard and Mega Minion), while the Rocket can defeat at least 14 other cards of equivalent level (e.g. Executioner, Night Witch, Sparky, Baby Dragon, Electro Dragon, Mini P.E.K.K.A, Bandit, Royal Ghost, Ice Golem, Miner, Elite Barbarians, Lumberjack, Archer Queen, and Inferno Dragon), as well as the cards that are taken out by the Fireball and Zap combo. Additionally, it uses one less deck slot.
* A Rocket is a decent counter to the Cannon Cart, turning it into a useless building which despawns after 30 seconds, which is beneficial as long as the player does not need to push into its lane any time soon. This becomes an even more effective trade if other units like a Princess Tower can be caught in the Rocket's blast, as the Cannon Cart costs one less than the Rocket.
* In a pinch, it can be used to stop a lone Balloon or Ram Rider, however that is a negative Elixir trade, so it is recommended to only use it if they are accompanied with other troops.
* Do not use a Rocket on a lone Battle Healer. Not only is it a negative Elixir trade, she will survive it and then heal back up with her passive healing, which will force you to spend additional Elixir to defeat her.
