'''Damage Amplification''' or '''Damage Amp''' is a stat that multiplies the damage caused by the player to affected enemies and NPCs. It can be both positive and negative. In latter case it reduces damage and is also known as '''Damage Reduction'''.

== Damage Reduction ==
'''Damage Reduction''' is a negative form of Damage Amplification, that reduces the damage output of enemies or its user.


== Calculation ==
== Calculation ==
Contrary to what the percentages might suggest, multiple sources of damage amplification do not all stack in the same way. There are three distinct categories of Damage Amplification, each interacting with the damage formula differently:
Multiple sources of abilities and items that display damage amplification percentages (e.g., +20% Damage), do not simply add together. Instead, they stack '''multiplicatively''', '''augmented'''.
 
Multiple sources of abilities and items that display damage reduction percentages (e.g., -30% Damage), simply '''add''' together. (Though this is most probably a bug)
 
=== Calculating Damage Amplification ===
To find your '''amplification''', use the following formula:
 
<math>\text{Amplification} = (1 + \text{A}_1) \times (1 + \text{A}_2) \times ...</math>
 
'''Example:'''
 
# {{HeroIcon|Drifter}} deals a base bullet damage of '''41'''.
# {{HeroIcon|Drifter}}'s base {{AbilityIcon|Bloodscent}} amplification of '''15%''' will increase his bullet damage from '''41''' to '''47''' (41 x 1.15 = 47.15, rounded down in game).
# {{HeroIcon|Ivy}} casts {{AbilityIcon|Air Drop}} on {{HeroIcon|Drifter}} to give him an additional '''20%''' amplification.
# {{HeroIcon|Drifter}} now deals '''57''' bullet damage (41 x 1.15 x 1.20 = 56.58, rounded up in game).
 
=== Calculating Damage Reduction ===
Notice: While Valve has stated in the May 22nd patch that Damage Reduction stacks '''diminishingly''', this is not true. Damage Reduction still stacks '''additively'''. Unless there was a hidden patch note, it is safe to assume that this is a bug. This means that the current formula is:
 
<s><math>\text{Damage Reduction} = (\text{DR}_1) + (\text{DR}_2) +...</math></s>
 
'''Example:'''


* '''Additive Amps:''' These add together with each other (including additive Damage Reductions) into a single pool.
# {{HeroIcon|Drifter}} deals a base bullet damage of '''41'''.
* '''Multiplicative Amps:''' These multiply the total damage one by one.
# {{HeroIcon|Mirage}} casts base {{AbilityIcon|Fire Scarabs}} on {{HeroIcon|Drifter}}, reducing his damage by '''20%''', decreasing his bullet damage from '''41''' to '''33''' (41 x 0.8 = 32.8, rounded up in game).
* '''Instance Amps:''' These are nearly identical to multiplicative amps, main exception being they create a new instance of damage.
# {{HeroIcon|Mirage}} now afflicts {{HeroIcon|Drifter}} with {{AbilityIcon|Inhibitor}}, reducing his damage by another '''30%'''.
# {{HeroIcon|Drifter}} now deals '''20''' bullet damage (41 x 0.5 = 20.5, rounded up in game).


=== The Damage Formula ===


Based on testing, the generalized formula for how these amps apply to weapon damage is as follows:
(Wiki admins feel free to remove this but just in case this gets fixed I'll keep it up here.)


<math>\text{Damage} = [(\text{Base Bullet Damage} \times \text{Weapon Multiplier}) \times (1 + \text{Total Additive Amps}) + \text{Flat Bonus}] \times \text{Multiplicative Amp}_1 \times \text{Multiplicative Amp}_2 \dots \times \text{Instance Amp Damage}_1 \times \text{Instance Amp Damage}_2</math>
For now this is not true, but to find your '''damage reduction,''' use the following formula:


<s><math>\text{Damage Reduction} = 1 - (1 - \text{DR}_1) \times (1 - \text{DR}_2) \times ...</math></s>
'''Example:'''  
'''Example:'''  
# {{HeroIcon|Drifter}} deals a base gun damage of '''41'''.
# {{HeroIcon|Mirage}} casts base {{AbilityIcon|Fire Scarabs}} on {{HeroIcon|Drifter}}, reducing his damage by '''20%''', decreasing his bullet damage from '''41''' to '''33''' (41 x 0.8 = 32.8, rounded up in game).
# {{HeroIcon|Mirage}} now afflicts {{HeroIcon|Drifter}} with {{AbilityIcon|Inhibitor}}, reducing his damage by another '''30%'''.
# {{HeroIcon|Drifter}} now deals '''23''' bullet damage (41 x 0.56 = 22.96, rounded down in game).


# A hero has a base bullet damage of '''100''' and '''0''' flat weapon damage for simplicity.
=== Calculating Total Amplification ===
# The hero is affected by {{ItemIcon|Inhibitor}} (an Additive Damage Reduction of '''-30%'''). Their damage drops to '''70''' (100 * 0.70 = 70).
To find the total '''amplification''', use the following formula:
# {{HeroIcon|Ivy}} casts {{AbilityIcon|Air Drop}} on the hero (an Additive Amp of '''+20%'''). The additive pool is now -30% + 20% = -10%. The hero deals '''90''' damage (100 * 0.90 = 90).
# The hero parries an enemy hero (Multiplicative Amp of '''+25%''' against parried target''')'''. This is applied after the additive pool. The hero now deals '''112.5''' damage (90 * 1.25 = 112.5).


== Damage Amplification ==
<s><math>\text{Total Amplification} = (\text{Base Damage} \times \text{Total A}) \times \text{Total DR}</math></s>
'''Example:'''
# {{HeroIcon|Drifter}} deals a base gun damage of '''41'''.
# With {{AbilityIcon|Bloodscent}}, {{HeroIcon|Drifter}}'s gun damage is '''47''' with a '''15%''' increase.
# {{HeroIcon|Mirage}} now afflicts {{HeroIcon|Drifter}} with {{AbilityIcon|Inhibitor}} and {{AbilityIcon|Fire Scarabs}}, reducing his damage by '''50%'''.
# {{HeroIcon|Drifter}} now deals '''24''' bullet damage.
Damage Reduction from self-inflicted sources of damage work the same as damage reduction does currently, they are '''additive'''. If you have {{ItemIcon|Golden Goose Egg}} {{ItemIcon|Cursed Relic}}, or {{ItemIcon|Cheat Death}} (active portion), they will add onto any other damage reduction you have.


=== Sources of Damage Amplification ===
Notice: Additional Amplifications seem to interact weirdly with this formula, I assume it's wrong. Having the {{AbilityIcon|Air Drop}} on {{HeroIcon|Drifter}} alongside the debuffs from {{AbilityIcon|Fire Scarabs}} and {{AbilityIcon|Inhibitor}} make {{HeroIcon|Drifter}}'s bullet damage 33, which is actually a 42% decrease from the amplification, not 50%. Would appreciate if someone could check into this.

== Damage Reduction ==
=== Spirit Amp ===
 
{{Item stat table|Spirit Amp}}
'''Damage Reduction''' is a negative form of Damage Amplification, reducing the damage output of enemies or its user. Mechanically, standard Damage Reductions are treated as negative '''Additive Amps''' (see Calculation section).
 
=== Damage Reduction Stacking ===
 
Valve's May 22 patch notes state that Damage Reduction debuffs are intended to stack diminishingly (i.e., multiplicatively, in the same manner as Resistance)<ref>{{Update link|May|22|2026}}</ref>.
 
However, live testing confirms that standard Damage Reduction debuffs have not been fully migrated to this new system. Currently, Damage Reductions (such as {{ItemIcon|Inhibitor}} or {{AbilityIcon|Fire Scarabs}}) simply act as negative Additive Amps. This means they add directly together with other additive amps (positive or negative) rather than multiplying against each other.

==== Spirit Damage Reduction====
=== Spirit Reduction ===
 
Spirit Damage Reduction from {{HeroIcon|Infernus}}'s {{AbilityIcon|Afterburn}} (T2) and {{ItemIcon|Silencer}} does '''not''' behave like standard Damage Reduction. Multiple sources of Spirit‑specific reduction stack additively with each other (e.g., Afterburn T2 + Silencer = sum of percentages). This combined spirit reduction is then applied as a '''separate multiplier''', multiplicative with all other additive amps such as {{ItemIcon|Inhibitor}}.

== Bugs, Quirks, and Exceptions ==
* '''Additive Amps''' do not apply to many flat values, such as flat weapon damage bonuses, base damage for Melee abilities (Such as the bonus +60 damage from {{HeroIcon|Calico}}'s {{AbilityIcon|Leaping Slash}} T3 upgrade), {{ItemIcon|Capacitor}} active, {{AbilityIcon|Backstabber}}, etc.
* {{ItemIcon|Headhunter}}: Multiplicative non-instance amps are the only amps that work correctly with Headhunter damage.
* {{ItemIcon|Return Fire}}: Because Multiplicative Amps act as defensive stats on the target, if an attacker fires at a target with Return Fire while the attacker has an M-amp active against them, the attacker will take increased reflected damage.
* {{HeroIcon|Billy}}'s {{AbilityIcon|Blasted}} bullet amp is unique as it is a post-mitigation [[True Damage|true damage]] amp. Because of this, it does not work at all against barriers.
* {{ItemIcon|Silencer}} and {{HeroIcon|Infernus}}'s {{AbilityIcon|Afterburn}} Tier 2 Spirit Damage Reduction are exceptions to the standard Damage Reduction rule. They stack additively with themselves, but multiplicatively with other additive amps.
* {{HeroIcon|Celeste}}'s Spirit damage amp from {{AbilityIcon|Radiant Daggers}} works like a multiplicative amp but is affected by additive amp bugs (see the Additive Amps entry above).
