Damage Resistance: Difference between revisionsGive feedback

'''Damage Resistance''' refers to the [[Weapon Damage|Bullet]], [[Melee Attack|Melee]], and [[Spirit Power|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. [[Unit]]s have a unique "Damage Resistance" stat that is applied to all sources of damage, including [[Trooper]]s.

Most resistances stack multiplicatively; they are not added together. Sources of Resistance Reduction are multiplied together separately first. The total reduction is then subtracted from the total resistance. This has the consequence of resistance reduction being more effective on targets with higher resistance.

=== Bullet Resist ===

Bullet Resist reduces all incoming [[Weapon Damage]], including from abilities. [[Troopers]], [[Guardians]], [[Neutrals]] and the [[Mid-Boss]] deal weapon damage.

=== Spirit Resist ===

=== Melee Resist ===

Melee Resist reduces all incoming [[Melee Damage]], including from abilities.

In addition to Melee Resist gained from items, Bullet Resist affects all Weapon Damage, granting another source of resistance against Melee Damage. The only exception is {{HeroIcon|Venator}}'s innate Spirit-scaled Bullet Resist, although this is likely a bug.

=== Crit Reduction ===

Crit Reduction is a stat that reduces the critical damage (headshots) received by the hero. Not to be confused with [[Weapon Damage#Crit Multiplier|Crit Bonus Scale]], a stat that reduces the critical damage dealt by the hero to other targets.

Crit Reduction is an innate stat to balance heroes with large head hitboxes, and cannot be modified by items or abilities.

== Starting Damage Resistance ==

The following [[Hero|Heroes]] either have starting Damage Resistance values or gain resistance with [[Boon|Boons]] or [[Spirit Power]]. Boon and Spirit scaling resistances stack additively.

Note: Negative values indicate that the hero receives increased damage.

== Calculation ==

While items often display resistance as a flat percentage (e.g., +20% Resist), multiple sources of resistance do not simply add together. Instead, they stack '''multiplicatively'''.

To find your total resistance, use the following formula:

<math>\text{Total Resist} = 1 - (1 - R_1) \times (1 - R_2) \dots</math>

# Subtract from 1: (1 - 0.40) = '''0.60''' and (1 - 0.20) = '''0.80'''.

# Multiply the remainders: 0.60 × 0.80 = '''0.48'''.

# Subtract from 1: 1 - 0.48 = '''0.52'''.

# Your Total Resist is '''52%'''.

=== Calculating Resistance Reduction ===

'''Resistance Reduction''' (often called "shred") acts as a counter to resistance. It is calculated separately using the same multiplicative formula, and then subtracted from the target's resistance.

<math>\text{Final Resist} = \text{Total Resistance} - \text{Total Reduction}</math>

A target has '''52%''' Total Resistance (as calculated above). You attack them with two sources of Reduction: one providing '''25%''' and another providing '''20%'''.

'''Step 1: Calculate Total Reduction'''

<math>1 - (1 - 0.25) \times (1 - 0.20) = 0.40 \rightarrow \mathbf{40\%}</math>

<math>52\% - 40\% = \mathbf{12\%}</math>

The target has a final effective Resist of only '''12%'''.

=== Negative Resistance ===

If the Total Reduction is higher than the Total Resistance, the final value will be negative. This acts as a damage amplifier.

* '''30% Resist:''' You take '''70%''' of incoming damage.

* '''0% Resist:''' You take '''100%''' of incoming damage (True Damage).

* '''-30% Resist:''' You take '''130%''' of incoming damage.

== Effective Health ==

* {{ItemIcon|Monster Rounds}} increases Bullet Resist vs. NPCs by +{{#invoke:ItemData|get_prop|Monster Rounds|NonPlayerBulletResist}}.  

* {{ItemIcon|Escalating Resilience}} increases Bullet Resist by {{#invoke:ItemData|get_prop|Escalating Resilience|BulletResistPerStack}} per [[stack]] per shot when hitting enemy heroes, maxing at {{#invoke:ItemData|get_prop|Escalating Resilience|MaxArmorStacks}} Bullet Resist.

* {{ItemIcon|Spirit Rend}} reduces {{#invoke:ItemData|get_prop|Spirit Rend|TechArmorDamageReduction}} spirit resist on bullet hit from its component {{ItemIcon|Spirit Shredder Bullets}}, as well as an additional {{#invoke:ItemData|get_prop|Spirit Rend|MagicResistReduction}} spirit resist reduction per stack on headshots, up to a max of 4 stacks (-33% spirit resist total).
