“With each attack, she unleashes a powerful healing aura that restores Hitpoints to herself and friendly Troops. When she isn't attacking, she passively heals herself!”
The Battle Healer card is unlocked from the Spooky Town (Arena 12). She is a single-target, melee troop with high hitpoints and low damage. She wears armor that is similar to the Knight's, but her breastplate is a golden color, and her sword is rather short. She has a continuous healing effect that takes effect when she attacks, having four healing pulses with a small delay of 0.25 seconds between each one. When she is not fighting any unit for five seconds, she will begin healing herself. The amount of health healed per pulse is not consistent with the Heal spell. A Battle Healer card costs 4 Elixir to deploy.
Although she has low damage per second, her healing effect and high hitpoints will allow her to take out over half of a Princess Tower's hitpoints when left ignored, so she must be addressed.
Strong counters to a lone Battle Healer include mini tanks and swarms. The former will be able to out-damage her healing effect and survive with most of their health left for a counterpush, while the latter will overwhelm her due to her slow attack speed and low damage per hit. The Ice Golem cannot counter her due to its inability to attack units. However, in a larger push, it can be useful to kite her and other support troops into the other lane to separate them from the large tank and take advantage of the other Princess Tower's damage.
Air troops like Minions or Bats are effective counters to the Battle Healer, since she cannot attack air. Furthermore, these air troops can deal more damage than the amount she can heal herself. Be careful, though, because your opponent may bring spells like Zap or Arrows to take out these counters.
On defense, the Battle Healer works best with troops that are not immediately defeated from most spells, like the Hunter. Her healing effect will gradually build up as the push is taken care of, negating most of the spell damage dealt to the unit, allowing for a powerful counterpush.
She is best placed at the front of a push due to her health pool and the fact that her area heal only takes place when she is in combat.
She can also be placed behind another tank. She will engage slightly later, but her surviving time will be longer and allow her to heal other troops longer.
She has a great synergy with the Elixir Golem. The Elixir Golem tanks for her, then she tanks for the Golemites and the Blobs while also healing them so your opponent will have more trouble gaining Elixir.
If the player has air units such as Minion Horde that they'd like to counterattack with, they should be mindful of where they are on the map before deciding to use the Battle Healer. She moves at a Medium speed, meaning Minions will outpace her fairly quickly, and may end up going in front of the Battle Healer and reducing the effectiveness of the push.
The Battle Healer was made available before its general release on 2/12/19 via the Trophy Road, at 5150 and 6450 Trophies respectively.
She was also available in a Special Challenge on December 2nd as a reward for reaching 5 wins and 11 wins.
She was again available in a follow-up special challenge on December 23rd as a reward for reaching 3 wins and 9 wins.
On 3/12/19, the card description for the Battle Healer was changed slightly. It used to say, "With each attack, she unleashes a powerful healing aura that restores Hitpoints to friendly Troops. Outside of combat she passively heals herself!"
On 5/5/20, a Balance Update decreased the Battle Healer's hitpoints by 10%.
On 6/10/20, a Balance Update allowed the Battle Healer to hover, meaning it can cross the river and will collide with air troops instead of ground troops.
On 18/11/20, an update changed the hover mechanic. The Battle Healer and other hovering troops will no longer pass through buildings, push back air units, or bounce off the river when knocked back.
The Battle Healer's hovering mechanic was meant to be released alongside the card, but it was pulled back when a bug that made her invulnerable to ground-targeting splash such as Mega Knight and Sparky was discovered.
The Battle Healer is the only winged troop in the game that is not actually flying.
The Battle Healer is the first Card to use the Level Boost mechanic, where players can use the Card at the level equal to their own King Level for one Season.
