==Summary==
*The Healer is the eighth Elixir Troop unlocked at Barracks level 8, which requires Town Hall level 6. She is a flying unit and the only troop with no attacking capabilities, but can heal any ground troops.
*When the Healer is deployed, a pulsating circular aura appears around her. She will heal the closest unit or Hero to her, regardless of how damaged they are. For example, if she has already locked on to your Archer Queen, she will not heal anything else until the Archer Queen is destroyed.
*Healers do not heal air units (other Healers, Dragons, Balloons, Minions, Lava Hounds, etc.), unlike a which heals every kind of troop, as well as the Druid. Healers will also not affect any Siege Machines like the Wall Wrecker.
**The Healer will not heal if the ground troops have a combined housing space of 2 or less: this means it will not heal a Single Barbarian, nor will it heal a Wall Breaker.
*Note that Healers will heal heroes at a reduced rate different from that of other units; keep this in mind when using Healers with your heroes.
*
*When defending as a Clan Castle troop, she heals injured Clan Castle troops, Heroes and the Skeletons from Skeleton Trap.
*Unlike all other troops, Healers are measured in healing per second (abbreviated as HPS; stated in-game as "Heal"), rather than in damage per second.
**The same principle applies to the Druid's initial form.
*Each additional Healer affecting the same unit after the fourth will have a reduced effect on healing the unit. Only up to seven Healers can have an effect on a unit at a time.
==Strategies==
===Offensive Strategies===
*A Healer does not last long if she is in the range of an , so make sure you destroy the Air Defenses first or otherwise occupy them before sending in your Healer(s). One strategy to get rid of them is to send an indirect attacker like a Bowler, Electro Dragon, or Super Archer to snipe the Air Defense before it can be of use. The remaining Air Defenses can be a problem so be sure to use a few more troops or spells to take it out.
*An alternative to taking out the Air Defenses, doing a Hero Walk with a ranged hero will have sufficient range to negate the Air Defense.
*If at any point in the battle all of your non-healing troops are killed and you have no more non-healing troops or s/Earthquake Spells to deploy, the battle will end, even if you have Healers deployed that are still alive or non-Lightning/Earthquake Spells that are still in effect.
*You are able to heal a Healer with a or a Druid.
*As of the December 2015 update, the effect of stacking multiple Healers to heal the same target is reduced. The stacking effectiveness begins to decrease after 4 Healers and decreases drastically after 6 Healers. For this reason, it is not advised to use too many Healers on the same target as the healing efficiency will decrease if they are massed on one target, like the Archer Queen.
*A Healer can trigger air traps, including the Seeking Air Mine, so be careful when deploying them. Using Balloons will get rid of any SAMs lurking in your preferred spawning location. While the Air Bomb will usually not be enough to kill a Healer, the Seeking Air Mine will prove fatal for almost all Healer levels. Skeleton Traps set to air mode can chip away at a Healer if no other troops that can target air are nearby.
**You can use this to your advantage when a Hero from a walk with a Healer is defeated, you can pull the Healers with ground troops, thus activating air traps and helpful if you are using an air attack. However, for 14 housing space, it is not the most efficient way and should only be used in desperate situations and can be a final point of value for Healers.
*Despite the reduced healing rate on Heroes, the Healer is popularly paired with them to increase their survivability, in strategies known as Hero Walks. The most common Hero Walk is the Queen Walk, which involves your Archer Queen funneling and then eventually coming into the base with the help of Wall Breakers to destroy crucial defenses and cover for attacks like the Miner Hog Hybrid, Yeti Smash, BoWitch etc. This works due to the Archer Queen's high damage output.
**A second Hero Walk is the Warden Walk, where the Healers support the Grand Warden instead of the Queen. Due to the Warden's range being longer, he can outrange a small number of defenses (i.e. Wizard Towers and s) and so he and the Healers will come across less fire overall. This can be helpful for certain situations, such as facing a multi-target (when attacking the Inferno, the Queen will bring the Healers into the Inferno's range, while the Warden does not), and can also be done in tandem with a normal Queen Walk. However, due to the Warden's much lower DPS, it is only feasible at Town Hall 12 or above and when the Warden is at least nearly maxed (level 35 or above is considered the bare minimum). However, when the Grand Warden is equipped with the Rage Gem, this speeds up the funneling greatly, improving the chances of success as long as the attack is done correctly. 
**The third Hero Walk is the Champion Walk, which is much less popular because of the champion being defense-targeting and is fast in movement speed, thus only being able to heal when the hero is still, and it runs inside the base, which makes it unpredictable and hard to perform, as well as being ineffective on a whole when paired with the Champion, as the Hero's range is shorter, making the Healers vulnerable to fire from Air Defenses.
**The fourth Hero Walk is the King Walk, which is commonly used at Town Halls 7-8, due to being to the Barbarian King being the only hero. Since the King is a close ranged attacker, they aren't used very often at higher town hall levels, as he cannot cover the Healers well.
**If you are using any form of Hero Walk, consider first deploying Balloons to test for Seeking Air Mines. Not doing so can cause the Healers to be destroyed quickly by these Mines which will ruin the walk. You can even couple this further by using the Balloons to also protect other air troops such as s.
**When using any of the above Hero Walk strategies, one should pay attention to the timer. Using one will usually consume a significant amount of time which may leave insufficient time for the remainder of the attack (especially the Warden Walk due to his low DPS). As a result it may be desirable to execute other phases of the attack at the same time, such as additional funneling or a supporting kill squad.
**It's recommended to use 5 Healers as it ensures your hero will stay at high HP when being targeted by defenses, and also to ensure sufficient healing if a Healer is killed by a Seeking Air Mine.
*s will increase the Healer's HPS, just like how it increases any other troop's DPS. Doing so can be extremely useful for Hero Walk strategies; this extra HPS can save the Hero from a heavy assault from defenses without having to use their abilities. If placed properly, the Rage Spell will also affect the Hero, greatly increasing their damage.
===Defensive Strategies===
*Healers do not last long if they are in range of single-target or an so make sure you upgrade and protect your Air Defense as much as possible. Also make sure that it is not in the direct way of defense targeting troops, and is off to the side a little bit along with being protected by . This will make sure they do not attack that Air Defense.
**Put your Air Defense in the middle of the base to prevent ground troops like Giants from destroying it quickly.
*Since Healers take up 14 housing space, unless you wish to use them on offense, it is not recommended to request or donate them as she does almost nothing on defense and only heals other Clan Castle troops, Skeletons from Skeleton Traps and Heroes. There are much better troops with less or more capacity that would work better anyway.
*Seeking Air Mines can one shot a relatively leveled Healer. If you plan to counter ground attacks, put your Seeking Air Mines where you predict ground armies to be placed or where ground troops will attack.
==Upgrade Differences==
The Healer undergoes significant visual changes at all levels except levels 2 and 6.
*Initially, the Healer is a woman with long, white angelic wings and short, white hair. She wears a golden dress that ends in 4 long pieces. Her dress has a white 4 sided star.
**At level 3, the color of her aura and the color of her dress both turn from light yellow to a bright magenta color (similar to Elixir-pink or level 6 Walls).
**At level 4, her aura reverts to yellow but her dress remains the same.
**At level 5, her aura turns to white and her dress is now light blue. She also wears a light blue headband.
**At level 7, she now wears a blue tiara on her headband. She now has two auras, which pulsate in anti-phase from each other.
**At level 8, her wings turn bright yellow, and her headband changes to a hollow triangle (matching many aesthetics of Town Hall 15). Her auras are now differently colored, with one being yellow and the other being bright lavender.
**At level 9, her wings turn green, and her headband changes to a green strip. She now wears a green tiara and her aura turns green.

==Trivia==
*In the Chinese language setting of the game, the Healer is called "Angel", which the unit resembles.
* 
**Note: Having this many Healers is highly discouraged as your troops will have no offensive capabilities unless you bring Clan Castle troops or use them with heroes. However, at Town Hall 13, Mass Healers with all four heroes is a possible strategy.
*To prevent the player from getting softlocked when the player returns after 90 days of staying off the game, an all-Healer will be replaced by a different army, so that the player can still reclaim their base.
*Although Healers have no favorite target, as of the September 16, 2014 update, Healers now prioritize healing larger groups of troops.
*As a result of the diminishing effects of additional Healers, the maximum possible healing per second on any troop (barring the use of s) is exactly 5 times that of a single Healer's healing per second. For max-level Healers this is equal to 360 HPS, or 280 HPS on heroes.
*Because the Healer cannot attack, a battle will end if she is the only remaining troop on the battlefield.
*Defensive Healers will not try to escape the poison radius nor heal defensive Clan Castle troops and Heroes while being poisoned.
*In the Clash-a-rama! series, she was described as both quite pacifistic and an opportunist, as shown helping Barbarians in their Elixir refills, preventing Builders from chopping down trees and healing with a lower price. Unlike her Clash of Clans appearance, the Healer appears to be blind or severely myopic and can even mistake a Balloon for another Healer.
*Healers in Clash of Clans are vulnerable to anti-air traps. This was not the case between February 24, 2016 and August 25, 2016.
===Comparisons===
*The Healer is one of the several troops not to have Builder Base or Super Troop counterpart, the others are the Miner, Electro Dragon, Yeti, Dragon Rider, Golem, Ice Golem, and the Headhunter.
*The Healer, the Balloon, Rocket Balloon, Ice Hound and the Lava Hound are the only air troops in the Home Village that can only target things on the ground.
*The Healer, along with the Barbarian, Archer, Giant, Goblin, Wall Breaker, Balloon, Wizard, Dragon and P.E.K.K.A are the oldest units in the game.
*The Healer, along with the Wall Breaker, Minion and Valkyrie are the only troops to have higher levels with no visual changes.
*The Healer, along with the Valkyrie and the Yeti are the only troops that do not fully fill a complete set of fully upgraded Army Camps.
*The Druid and the Healer are similar in different ways:
**The Druid is a ground unit capable of healing both ground and air troops, but only for a limited time for 16 housing space, moves faster, and does not reduce the Hero Heal. However, he has less hitpoints, his healing is higher and is only limited to 5 targets, has a slower heal speed, and is prone to ground traps such as Spring Traps.
**The Healer is an aerial unit which heals only ground troops, and her heal type is splash, for 14 housing space. She has a higher heal speed and hitpoints, but she is slower, her healing is lesser and is reduced on Heroes, and is prone to air traps such as Seeking Air Mines.
*The Druid and Healer cannot heal each other, therefore they will stand still. However, when the Druid transforms into a Bear, she will heal the Bear.
**However, if another troop is close enough to the Healer (which can happen if the player deploys a troop with 2 or more housing space or a Hero), the Druid's healing will bounce onto the Healer and heal her.
