Damage Resistance

Damage Resistance refers to the Bullet, Melee, and Spirit Resist statistics which reduce incoming damage taken. Bullet Resist reduces all weapon and melee damage, Melee Resist reduces only melee damage, while Spirit Resist reduces all spirit damage.

Most resistances stack diminishingly with each additional resistance source having reduced effect. Resistance Reduction is applied to the final resistance, and if stacked separately and diminishingly.

The Bullet Resistance and Spirit Resistance stats are also sometimes referred to as "Bullet Armor" and "Spirit Armor".

Starting Damage Resistance

Most Heroes have no starting damage resistance. However, there are a few exceptions:

Bullet Damage Resistance

• Bebop has 10% bullet damage resistance.
• McGinnis has 15% bullet damage resistance.
• Dynamo has no starting bullet damage resistance, but he gains 1% on each power increase.

Spirit Damage Resistance

• Lash has 15% spirit damage resistance.
• Pocket and Trapper have -15% spirit damage resistance (they take 15% more spirit damage).
• Kelvin has no starting spirit damage resistance, but he gains 1% on power increase.

Headshot Critical Damage Resistance

• Seven has 35% headshot critical damage resistance.

• Mo & Krill have 20% headshot critical damage resistance (Mo's head only).

Melee Resist

Melee Resist is a special case of Bullet Resist that is stacked diminishingly along with Bullet Resist to reduce all incoming melee damage. This includes all "melee" abilities such as Viscous Puddle Punch ability.

Math

Despite being presented in-game as +x% Bullet, Melee, or Spirit Resist, multiple sources of resist stack multiplicatively, not additively.

The formula for resist is: $B{R}_f=\lceil 1-\prod _{i=1}^n(1-B{R}_i)\rceil$
where:
$\begin{array}{rl}B{R}_f& =\text{final bullet resist,}\\ n& =\text{number of bullet resist sources,}\\ B{R}_n& =\text{bullet resist value}\\ \end{array}$

For example, multiple sources of Bullet Resist:

• 60% Bullet Resist from Viscous' Goo Ball
• 40% Bullet Resist from the Colossus Item results in:

$1-(1-0.6)*(1-0.4)=76\mathrm{\%}\text{ Bullet Resist}$

Resistance Reduction

Resistance Reduction refers to any negative amount of Resist, making the target take increased damage.

Resistance Reduction is calculated multiplicatively like resistance, but then simply subtracted from the resistance amount.

${D}{i}{s}{p}{l}{a}{y}{e}{d}{R}{e}{s}{i}{s}{t}=[1-(1-{R}{e}{s}{i}{s}{t}{a}{n}{c}{e}{1})*(1-{R}{e}{s}{i}{s}{t}{a}{n}{c}{e}{2})*...*(1-{R}{e}{s}{i}{s}{t}{a}{n}{c}{e}{N})]-[1-(1-{R}{e}{s}{R}{e}{d}{u}{c}{t}{.}{1})*(1-{R}{e}{s}{R}{e}{d}{u}{c}{t}{.}{2})*...*(1-{R}{e}{s}{R}{e}{d}{u}{c}{t}{.}{N})]$

For example, using Bullet Resists and Reductions:

• 70% Spirit Resist from Viscous' Goo Ball
• 20% Spirit Resist from Spirit Armor
• -12% Spirit Resist from Spirit Strike
• -12% Spirit Resist from Mystic Vulnerability
• -24% Spirit Resist from Crippling Headshot

$[1-((1-0.7)*(1-0.2))]-[1-((1-0.12)*(1-0.12)*(1-0.24))]={3}5\mathrm{\%}SpiritResist$

The final Resistance can go negative, and this multiplies the damage taken of that type. For example:

• 30% resist= 70% of the damage from the weapon or ability.
• 0% resist = 100% of the damage from the weapon or ability.
• -30% resist = 130% of the damage from the weapon or ability.

Items like Headshot Booster grant a flat added bullet damage, this bonus damage is not multiplied by weapon damage but is subject to resistance reduction/increase in damage.

Even Resistance from Level#Power Increases is multiplicative. For example, Bebop's base Resistance is 0%, while he gains 1.25% Resist per Power Increase. After 14 Power Increases, Bebop's total resistance will be $0.1+1-(1-0.0125{)}^{14}=26.2\mathrm{\%}$
