Damage modification

Damage amplification increases the damage dealt or taken by a hero.

Abilities that amplify damage dealt

Hero	Ability	Amount
Ana	Nano Boost	+50%
Baptiste	Amplification Matrix	+100%
Mercy	Caduceus Staff	+30%
Orisa	Supercharger	+50%

Caduceus Staff, Nano Boost, and Supercharger are considered damage boosts. Projectiles are only amplified by them if the hero was being damage boosted when they were released.

Abilities that amplify damage taken

Hero	Ability	Amount
Zenyatta	Orb of Discord	+25%

Abilities that cannot be damage boosted

The following abilities cannot have their damage dealt amplified by damage boosting the hero.

Most of these are also applicable with Amplification Matrix, except B.O.B.'s charge attack, which can be amplified via damage boosts but not with Amplification Matrix, and Torbjörn's turret, which cannot be amplified via damage boosts but can with Amplification Matrix.

• Ashe: B.O.B.
  • B.O.B.'s own damage can be amplified, but amplifying Ashe's damage does not affect B.O.B. (Currently bugged.)
• D.Va: Self-Destruct
• Hanzo: Dragonstrike
  • The arrow can be amplified, but the dragons cannot.
• Junkrat: Steel Trap, RIP-Tire
• Sigma: Gravitic Flux
  • The lift can be amplified, but the slam cannot.
• Symmetra: Sentry Turret
• Torbjörn: Deploy Turret, Molten Core
  • The turret's own damage can be amplified with Amplification Matrix, but amplifying Torbjörn's damage does not affect the turret. (Currently bugged.)
  • The impact damage from Molten Core can be amplified, but the damage over time cannot.
• Widowmaker: Venom Mine
• Wrecking Ball: Minefield
• Zarya: Graviton Surge
  • The impact damage from Graviton Surge can be amplified, but the damage over time cannot.

(NOTE: The current patch has a bug where Torbjörn's turret and B.O.B. do get their damage amplified if their owners get amplified. Interestingly, it is only B.O.B.'s arm cannons that are affected by this bug.)

Calculation

The equation used to calculate damage in general is as follows:

Damage = base damage × (100% + damage dealt modifiers) × (100% + damage taken modifiers) × headshot multiplier (if applicable) − armor (if applicable)

Damage dealt modifiers and damage taken modifiers are applied separately. This means that if Zenyatta's Orb of Discord (+25% damage taken) is on a target and an attack boosted by Mercy's damage boost (+30% damage dealt) hits that target, the damage would be 162.5% of the base damage.

Multiple amplification effects of the same category—damage dealt or damage taken—are added together. For example, if Ana uses Nano Boost (+50% damage dealt) on a target who then shoots through Baptiste's Amplification Matrix (+100% damage dealt), the damage would be 250% of the base damage.

Interaction with damage reduction

Damage reduction from abilities such as Fortify, Ironclad, Nano Boost, and Take a Breather modify damage taken, just like damage taken amplifiers. This means they add together when combined, and apply separately from damage dealt modifiers. If Orb of Discord (+25% damage taken) is on Bastion with Ironclad (−20% damage taken), Bastion takes 105% of all incoming damage.

The lowest the damage taken value can go is 50%. If a Bastion with Ironclad (−20% damage taken) gets Nano Boosted (−50% damage taken), Bastion's damage taken is 50% because it cannot be lower than that. However, if that Bastion is then affected by Orb of Discord (+25% damage taken), Bastion's damage taken would be 55% because it is only the overall damage taken value that is limited to 50%, not damage reduction effects.

Trivia

• Mercy gains ultimate charge equal to 130% of the damage she amplified, as a rule of thumb.
• Hypothetically, the highest damage dealt value is 330% and the highest damage taken value is 125%. Combined, the maximum damage amplification would be 412.5%. This can then be further increased with the headshot multiplier. Using Widowmaker's 2.5× headshot multiplier, the absolute highest increase from the original damage would be 1031.25%.
• Healing amplification works the same way as damage amplification, though the only healing dealt amplifier is Amplification Matrix (+100% healing dealt) and the only healing taken amplifier is Biotic Grenade (+50% healing taken). Together, the target would gain 300% of the base healing.
