  • The Healer is a flying unit that is unlocked at Barracks level 8. She is 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. If all units have full health, she will start healing the closest troops (although it will have no effect on the healed troops). If a ground troop is damaged by a defense, she will fly over and start healing.
  • Note that Healers will not heal air units (other Healers, Dragons, Balloons, MinionsLava Hounds, etc.), unlike a Healing Spell which heals every kind of troop. Healers will also not heal ground Siege Machines like the Wall Wrecker.
  • 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.
  • Healers cannot attack at all. They are completely unable to defend themselves, and will totally ignore any enemy buildings or troops attacking them. If they have no target to heal, they will simply remain stationary even if they are taking damage.
  • 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.
  • Each additional healer affecting the same unit after the fourth will have a reduced effect on healing the unit. Only up to eight Healers can have an effect on a unit at a time.


Offensive Strategy

  • A Healer does not last long if she is in the range of an Air Defense, so make sure you destroy the Air Defenses first or otherwise occupy them before sending in your Healer(s). One strategy is to send a few Wall Breakers in to break the Wall that is protecting the Air Defense. Then send in a group of Giants (usually 12 or more) to destroy it. The remaining Air Defense can be a problem so be able to use a few more troops to take it out. Finally, send in a Healer along with other troops after the Giants. As long as the Healer does not get distracted by other troops taking damage, or is not killed by an Archer Tower or Wizard Tower, the Giants will live for a significant amount of time (due to the constant healing) and will distract the defenses while the other troops destroy everything. This is known as a Giant-Healer raid and is pretty effective when attacking a Town Hall 6, and extremely effective against Town Hall 5s since there is only one Air Defense in this Town Hall level.
  • Another strategy is to use Balloons to tank the hits from an Air Defense. Since Balloons target defenses, there is a good chance that the Balloons will be closer to the Air Defense than the Healer. The Balloons may also destroy the Air Defense too.
  • If at any point in the battle all of your non-Healer troops are killed and you have no more non-Healer troops or Lightning Spells/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.
  • Healers can allow Giants and other defensive troops to withstand massive amounts of damage, even doubling that of their normal health. Support durable troops like Giants or P.E.K.K.As with Healers.
  • You are able to heal a Healer with a Healing Spell.
  • 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. 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.
  • A popular strategy called the Queen Walk is where players place many Healers surrounding an Archer Queen or other heroes. This is usually done to take out Air Defense when using air attacks, or to create a funnel for other troops.
    • If you are using an air attack with a Queen Walk, consider first deploying some lesser troops where the Queen will be deployed, such as Balloons, to test for Seeking Air Mines. Not doing so can cause the Healers to be wasted quickly by these Mines which will ruin the Queen Walk.
      • You can even couple this further by using the Balloons to also protect Baby Dragons, a common funneling troop used in Queen Walks.
    • A variant of the Queen Walk is the Queen Charge, where the Queen herself is funneled into the base (rather than walking around it), possibly with the assistance of Wall Breakers and other troops to do so. The Queen Charge can serve various purposes, such as destroying the Eagle Artillery and/or Clan Castle troops to allow another part of the army to attack.
    • A second variant of the Queen 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 Bomb Towers) 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 Inferno Tower (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 or Queen Charge. However, due to the Warden's much lower DPS, it is only feasible at Town Hall 12 and when the Warden is at least nearly maxed.
    • When using any of the above 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. 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.
  • Rage Spells will increase the Healer's HPS, just like how it increases any other troop's DPS. Doing so can be extremely useful for Queen Walk strategies; this extra HPS can save the Archer Queen from a heavy assault from defenses without having to use her ability.

Defensive Strategy

  • Healers do not last long if she is in range of single-target defenses or an Air Defense 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 Walls. This will make sure they do not attack the air defense.
  • Since Healers take up 14 housing space, it is not recommended to donate for defense her as she does almost nothing on defense and only heals other Clan Castle troops, Skeletons from Skeleton Traps and heroes.
  • Seeking Air Mines kill 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 has long, white angelic wings with 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 six 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.


  • In the Chinese language setting of the game, the Healer is called "Angel", which the unit resembles.
  • As part of the 23 May 2013 update, Healers had their training costs reduced at all levels. The training time was shortened from 20 minutes to 15 minutes and the required housing space was lowered from 20 to 14.
  • You can have a maximum of 21 Healers at one time in a complete set of fully upgraded Army Camps. This number increases to 24 if you include the 3 that can fit into a level 9 or higher Clan Castle. On the battlefield, you can clone an additional 8 Healers with four level 5 or higher Clone Spells (three from the regular spell inventory and one from a max-level Clan Castle).
    • Note: Having this many Healers is highly discouraged as your troops will have no offensive capabilities unless you bring Clan Castle troops or heroes. However, at Town Hall 13, mass Healers with all four heroes is a possible strategy.
  • Although Healers have no favorite target, as of the September 16, 2014 update, Healers now prioritize healing larger groups of troops.
  • Prior to the September 2014 update, a Healer in a defensive Clan Castle would heal damaged buildings. This is no longer true and she will now only heal Heroes and other Clan Castle troops when defending; if Heroes and Clan Castle troops are taken out, she will do nothing for the rest of the defense.
  • As of the February 24th, 2015 update, Healers no longer trigger air traps or traps set to air mode. This change was reverted in a balance update on August 25th, 2016.
  • Part of the May 4th, 2016 update, the Healer's training time has been decreased from 15 minutes to 10 minutes.
  • Healers’ heal radius was reduced from 2 tiles to 1.5 tiles as part of the June 18th, 2019 Update.
  • As a result of the diminishing effects of additional Healers, the maximum possible healing per second on any troop (barring the use of Rage Spells) 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.
  • Also, in Clash-a-rama, she was seen to be blind.
