Mercy Abilities and Role Explained
In contrast to many of other Overwatch Supports, Mercy’s playstyle revolves around consistent single-target healing, also known as “pocketing.”
Additionally, she has the ability to go from healing a teammate to boosting their damage instantly, allowing her team to focus damage and break through enemy barriers in a pinch.
While she may have weak weapon damage and poor mobility that forces her to rely on teammates, Mercy’s ability to bring players back to life with Resurrect is a tremendous asset to any team.
How to Use Caduceus Staff
Mercy’s primary weapon is her Caduceus Staff, which defaults to creating a healing tether on ally targets within a max range of 15 meters and a healing power of 55 per second.
When holding down the Caduceus Staff’s secondary fire, Mercy switches from a healing tether to a damage-boosting tether that increases her ally’s damage by 30%.
Depending on the situation, you may find yourself healing more than damage-boosting, and vice versa, though we recommend alternating between the two based on your team’s needs.
Note that either tether will break if the ally you’re targeting goes beyond the Caduceus Staff’s maximum range or moves out of your direct line of sight, such as behind a wall or the payload for a few seconds.
How to Use Caduceus Blaster
Mercy’s secondary weapon is her Caduceus Blaster, a small pistol with pinpoint accuracy that fires a stream of rapid-moving projectiles akin to D.Va’s Light Gun, at a rate of 5 rounds per second.
While its damage is relatively weak, namely at long range, the Caduceus Blaster’s close-range potential should not be overlooked, especially if you can consistently land headshots.
In addition, the weapon will automatically reload whenever Mercy switches back to using the Caduceus Staff after a short delay, saving you precious in-game moments.
However, you should keep in mind that it’s generally smarter to boost an ally’s damage rather than pull out Mercy’s Blaster since it leaves the rest of your team exposed.
How to Use Guardian Angel
By default, Mercy has pretty terrible mobility, limited to walking and short hops, so her Guardian Angel ability is a must for getting around the map and staying alive.
When you activate it, Mercy will fly over to an ally you select regardless of whether they’re alive or dead, allowing her to heal, damage-boost, or resurrect the targeted teammate.
Tethered allies are auto-targeted by default, but you can also manually select who you want to fly to as well as change these settings in the Mercy-specific controls menu.
With a short cooldown of 1.5 seconds and a max range of 30 meters, Guardian Angel is perfect for jumping between allies to heal them quickly or get away from potential threats.
How to Use Resurrect
The most powerful tool in Mercy’s belt is Resurrect, which previously let her revive her entire team but has since been reworked to bring a single target within a 5-meter radius back to life.
The revived teammate will respawn in the spot where they died with a brief period of invulnerability, during which they can still move but are unable to attack or use any abilities.
It’s incredibly useful in a pinch and can help turn the tide of battles, but only if you exercise good judgment in whom you bring back since it has a long 30-second cooldown that doesn’t reset upon dying.
The best approach is to prioritize certain teammates over others, primarily Tanks, though it can be more beneficial to resurrect a Support or DPS that has their Ultimate ability fully charged.
How to Use Valkyrie (Ultimate)
When activated, Mercy’s Ultimate Valkyrie will enhance the rest of her abilities while allowing her to fly freely in the sky and provide her with infinite ammo on her Caduceus Blaster.
Additionally, healing and damage-boost tethers will momentarily split to affect all allies within a set radius of the teammate she’s currently targeting.
While not as powerful as her original Resurrect, Valkyrie is excellent for making a comeback since Mercy can focus on multiple targets and quickly move around the map without relying on her teammates.
The only downside is flying high in the air leaves Mercy exposed to snipers like Widowmaker and Hanzo, so staying in motion and moving unpredictably are essential for survival.
Mercy is unmatched as far as healers are concerned, even though other Supports like Ana and Baptiste are better at providing heals to multiple teammates at once.
With both Resurrect and Valkyrie at her disposal, Mercy can play a big role in setting the tone and pace for battles and is often the driving force behind every comeback.
Although she works well with just about every team composition, some heroes stand to benefit from Mercy’s playstyle more than others, so below we’ll go over the best options.
Which Heroes Combo Best With Mercy?
- Zenyatta – While Zenyatta’s healing abilities pale in comparison to Mercy’s when combined, the pair can provide significant healing over time.
- Reinhardt – With Mercy by his side, Reinhardt can play more aggressively and soak up damage in exchange for protecting her with his shield.
- Pharah – Also known as “Pharmercy” or “Pharmacy,” mixing a Pharah with good aim and a pocket mercy by her side can become unstoppable if left unchecked.
- Ashe – Mercy pairs well with DPS heroes who can fully utilize her damage boost and Ashe is among the best in the game.
- Sigma – As a frontline DPS/tank hybrid with a relatively small healthpool, Sigma relies on Mercy for healing in between shield setups.
- Bastion – A well-placed bastion turret that’s damage boosted by Mercy can spell out disaster for the opposing team if not dealt with accordingly.
The best healers in any game are often balanced out with a handful of weaknesses such as small healthpools, poor mobility, weak damage, and Mercy is no different.
When isolated, Mercy moves incredibly slow compared to other heroes, and many of her abilities have the unfortunate side effect of leaving her exposed for several seconds, namely Resurrect.
With that said, there are a lot of heroes who pose a threat to Mercy if her teammates don’t step in to protect her; below, we’ll discuss which ones to look out for most.
Which Heroes Does Mercy Struggle Against?
- Roadhog – Will often try to pull Mercy out from safety using his hook + left-click combo, killing her in one shot.
- Winston – Can catch Mercy by surprise and take her out quickly if there aren’t any nearby tanks to defend her.
- D.Va – Similar to Winston, D.Va will get right up in Mercy’s face and spam missiles any chance she gets.
- Tracer – Quick enough to slip past tanks and attack Mercy from behind.
- Genji – Another high mobility hero who can eliminate Mercy if left unguarded.
- Reaper – Loves to sneak into teams’ backlines and rip through squishy supports, including Mercy.
- Mei – Can stop Mercy dead in her tracks using freeze and block her off from teammates with Ice Wall.
- Sombra – Similar to Reaper, Sombra is prone to sliding her way into your team’s backline where Mercy tends to hang out.
- Widowmaker – Can kill Mercy with a single shot and discourage her from hovering in the air for too long.
General Tips for Playing Mercy
Mercy is a Support main’s dream character, complete with all the tools to keep a team alive and turn the tide of battles when things start looking bleak.
However, she can be tough to play as at higher ranks where players have a better sense of game mechanics and can find ways to isolate and focus damage on her.
As long as you have a good team backing you up, you should be fine, but here are some other general tips to take with you into battle.
- Mercy will passively heal herself by not taking damage for a while, so don’t be afraid to take a break from healing and hide out until you’ve recovered.
- While airborne, Mercy will slowly fall to the ground by pressing and holding the jump button, allowing you to feather your jumps to throw off enemies and stay close to airborne allies.
- Mercy pairs well with allies who can’t self-heal or excel at long-range damage, allowing her to boost their damage without putting herself directly in harm’s way.
- Avoid using Guardian Angel to rescue a teammate immediately; instead, gauge the situation and determine whether or not you can land safely without dying.
- Pay attention to what abilities your teammates are using and look for opportunities to maximize damage output from offensive Ultimates.
