Damage Resistance

“Let's get started, shall we?”

This article is a stub. You can help the Deadlock Wiki by expanding it.

Damage Resistance refers to the Bullet and Spirit Resist statistics which reduce incoming damage taken.

Bullet Resist reduces all weapon (such as bullets/melee) damage, while Spirit Resist reduces all spirit damage.

Resistances from Power Increases seems to act strangely and requires more research.

Notes

Resistances can go negative, and this multiplies the damage taken of that type.

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.

Math

Despite being presented in-game as +X% Bullet Resist, multiple sources of bullet resist stack multiplicatively, not additively.

The formula for bullet resist is: $BR_{f}=\left\lceil 1-\prod _{i=1}^{n}(1-BR_{i})\right\rceil$
where:
${\begin{aligned}BR_{f}&={\text{final bullet resist,}}\\n&={\text{number of bullet resist sources,}}\\BR_{n}&={\text{bullet resist value}}\\\end{aligned}}$

For example, multiple sources of Bullet Resist:

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

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

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.

${\mathit {DisplayedResist}}=[1-(1-{\mathit {Resistance1}})*(1-{\mathit {Resistance2}})*...*(1-{\mathit {ResistanceN}})]-[1-(1-{\mathit {ResReduct.1}})*(1-{\mathit {ResReduct.2}})*...*(1-{\mathit {ResReduct.N}})]$

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

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