Mercy's Caduceus Staff grants a teammate either healing or damage boosting. She can change to Caduceus Staff from Caduceus Blaster by pressing button 1 (or mouse-scrolling). Primary fire projects a yellow beam that heals the target at the rate of 60 HP per second. Secondary fire projects a blue beam that grants the target a 30% increase to their damage output. Both beams will tether onto the target. The target's name and health will be immediately displayed below the crosshairs.
Regardless of which direction Mercy is facing, the beam will stay locked on the target. As long as its target is within 15-meter range and there are no solid objects obstructing the beam. The beam will, however, remain locked on for 2 seconds before cutting out. Within that 2 seconds, if the connection is established again by staying within the range and line-of-sight, the ability will not be disrupted.
Because the calculation for damage happens when a projectile or hitscan connect to the enemies, Mercy is only able to successfully boost her teammate by tethering her secondary beam to her teammates when their attacks connect, not when the attacks are fired.
Mercy cannot target to boost or heal any objects such as turrets, Teleporters, Shield Generators, RIP-Tires, Superchargers, etc. However, she can boost the attack of other objects which are created by abilities by boosting its owner. For example, she cannot boost Torbjörn's turrets by tether onto Torbjörn, while she can boost the effect of a Venom Mine by boosting Widowmaker.
Mercy is able to fill her ultimate charge from both healing and damage boosting. However, she cannot build her ultimate charge if she boosts heroes who are attacking themselves, Mei's Ice Wall, barriers, etc.
In the Game Options, Mercy has two options that affect her Caduceus Staff:
- Toggle Beam Connection: When enabled, pressing the appropriate button will toggle the staff between 2 beams. Otherwise, the button must be held.
- When Toggle Beam Connection disabled, players can cancel the ability be releasing the button.
- When Toggle Beam Connection enabled, players can cancel the ability by either changing to other beam or looking in another direction without any teammate and clicking the button again.
- Beam Sensitivity: Adjust the sensitivity of Caduceus Staff's targeting. The less value it is, the closer the distance between crosshair and the teammates has to be for tethering a beam.
- The Biotic Stream of the Caduceus Staff greatly enhances natural reflexes and healing processes.
