Weapon Damage Formula

The formula for calculating weapon damage is:

$F i n a l W e a p o n D a m a g e = (B a s e B u l l e t D m g * W e a p o n D m g % * D m g B o n u s % + F l a t W e a p o n D m g) * D m g F a l l o f f * (B u l l e t R e s i s t % - B u l l e t R e s i s t R e d u c t i o n %) * I n c r e a s e d B u l l e t D m g % * C r i t M u l t i p l i e r$

Base Bullet Damage

The Amount of damage your Hero will do while having no items. This is different for each hero and it increases based on your level. All heroes gain levels at the same soul milestones.

The formula for Base Bullet Damage is:

$B a s e B u l l e t D a m a g e = \sum_{k = 1}^{15} (p_{i})$

$\begin{matrix} p_{i} & = The damage acquired through each power increase \\ 15 & = Number of total power increases \\ i & = the index of the power increase \end{matrix}$

Grey Talon is an exception to the rule, additionally increasing his Base Bullet Damage based on his Spirit Power acquired through items.

Weapon Damage

The percentage of damage acquired through items and golden statues

The formula for weapon damage is:

$x_{f} = x_{i} * (1 + \sum_{i = 1}^{n} Shop Bonus + \sum_{i = 1}^{n} Golden Statues)$

where:

$\begin{matrix} x_{f} & = final weapon damage, \\ x_{i} & = initial weapon damage, \\ S h o p B o n u s & = Increase based on the tier, \\ G o l d e n S t a t u e s & = Golden Statue value \end{matrix}$

Golden Statues can provide a permanent increase: +3% before 10 minutes, +4% before 30 minutes and +7% after 30 minutes.

All weapon items provide Weapon Damage based on their Tier.

Tier 1 items provide +6%, Tier 2 items provide +10%, Tier 3 items provide +14%, and Tier 4 items provide +18%. The following items grant increased weapon damage:

Flat Weapon Damage

An extra amount of damage obtained through the use of second abilities on particular heroes.

Flat Weapon Damage is not affected by Weapon Damage, it's an additive damage source and it's not multiplied with the total multiplication that comes from Base Bullet Damage, Weapon Damage and Damage Bonus, but added in top of it.

However, it is later multiplied by Damage Falloff, Bullet Resist, Bullet Damage and Crit Multipliers

Some sources of Flat Weapon Damage are:

Hero	Ability	0	2	5
Abrams	Shoulder Charge			+5.5 Weapon Damage for 8s after colliding with an enemy
Grey Talon	Rain of Arrows	+4Weapon Damage	While airborne, +5 Weapon Damage and weapon damage applies 40% movement slow for 1.5s
Lash	Grapple		+20m Cast Range and gain +6 Weapon Damage for 10s (Able to stack)
Pocket	Flying Cloak			+7 Weapon Damage for 10s after teleporting with Flying Cloak.
Yamato	Flying Strike			Can Grapple to ally Heroes and +6 Weapon Damage for 10s

Damage Falloff

The amount of weapon damage reduction a hero experiences in relation to their distance from a target entity. The greater the distance between the attacker and their target, the less weapon damage they are able to do.

All heroes have a Falloff Range, comprised of two distances that mark the start and end, in which their weapon damage is linearly reduced.

Damage Falloff makes Weapon Damage drop from 100% ( $D i s t a n c e < F a l l o f f R a n g e S t a r t$ ) to 10% ( $D i s t a n c e > F a l l o f f R a n g e E n d$ ) for all heroes, the only difference between heroes being their respective Weapon Falloff Ranges.

When aiming at an enemy hero, the percentage of inflicted Weapon Damage can be approximated by the player through a dot located at the left side of the enemies health bar that gradually turns from yellow to red.

*Dot colors and their approximate Weapon Damage percentage ranges.^[1]*
Dot Color	Damage Percentage
Red	10% - 20%
Orange	20% - 35%
Yellow	35% - 75%
Transparent	75% - 100%

Falloff Range can be increased by buying Sharpshooter, a Tier 3 Weapon Item.

Bebop is able to increase his Falloff Range by upgrading his first skill:


Hero	Ability	0	1	2	5
Bebop	Exploding Uppercut			On Uppercut enemy Hero, gain fast spin-up time, 2x range, and +60% weapon damage for 12s

However, Exploding Uppercut bonus Falloff Range can't be stacked with Sharpshooter.

Damage Falloff affects all types of damage listed so far, these being:

Base Bullet Damage
Weapon Damage
Damage Bonus
Flat Weapon Damage

Damage Falloff does not affect the Weapon Damage done by Hollidays third ability Crackshot.

Bullet Resist - Bullet Resist Reduction

Bullet Resist

Bullet Resist is a reduction of the damage taken by a hero. The formula for Damage Resist is:

$B u l l e t R e s i s t = 1 - \prod_{i = 1}^{n} (1 - p_{i})$

$\begin{matrix} p_{i} & = each instance of Bullet Resist \\ 1 & = Damage recieved from a gun \\ n & = Number of total Bullet Resist sources \\ i & = the index of the item that is giving Bullet Resist \end{matrix}$

Explanation of the formula:

Each instance of Bullet Resist is deducted from 100% of the damage received from a gun. This calculation is then repeated for each instance of Bullet Resist the hero has on. Once all these deductions have been calculated, the results are multiplied. The result of this multiplication is then deducted from 100% of the damage given initially. The result of this process is the Bullet Resist.

Bullet Resist Reduction

Bullet Resist Reduction is a reduction inflicted upon an enemy. The formula for Damage Resist Reduction is similar to the Bullet Resist one:

$B u l l e t R e s i s t R e d u c t i o n = 1 - \prod_{i = 1}^{n} (1 - p_{i})$

$\begin{matrix} p_{i} & = each instance of Bullet Resist Reduction \\ 1 & = Damage recieved from a gun \\ n & = Number of total Bullet Resist Reduction sources \\ i & = the index of the item that is giving Bullet Resist Reduction \end{matrix}$

Explanation of the formula:

Each instance of Bullet Resist reduction is deducted from 100% of the damage received from a gun. This calculation is then repeated for each instance of Bullet Resist Reduction the hero has on. Once all these deductions have been calculated, the results are multiplied. The result of this multiplication is then deducted from 100% of the damage given initially. The result of this process is the Bullet Resist Reduction.

Result

To calculate the final Bullet Resist you have to calculate the difference between Bullet Resist and Bullet Resist Reduction

Increased Bullet Damage

A personal debuff you inflict on enemies. It multiplies the amount of damage they take from you but not your allies.

Increased Bullet damage is not the same thing as Weapon Damage. as Increased Bullet Damage takes into account your Flat Weapon Damage.

There are only four known instances of Increased Bullet Damage, all coming from heroe's abilities:

Hero	Ability	1	2	5
Bebop	Hook	Bebop deals 30% more weapon damage against hooked enemies for 10s
Dynamo	Kinetic Pulse		Dynamo deals 30% more Weapon Damage to hit enemies for 8s
Grey Talon	Spirit Snare			Grey Talon deals +30% more Bullet Damage to enemies hit by Spirit Snare for 10s
Warden	Binding Word			Warden deals +20% more Bullet Damage to trapped Heroes for 6s

Crit Multiplier

Formula

$C r i t M u l t i p l i e r = H e a d s h o t * C r i t B o n u s S c a l e * C r i t R e s i s t$

Headshots

Aiming for the head will deal increased damage. Troopers, Guardians, and Heroes have a weakpoint hitbox that receives approximately double base bullet damage when hit by a weapon.

Several items have effects that proc on headshots, such as Headshot Booster, Headhunter, and Crippling Headshot.

Crit Bonus Scale

Crit Resist

Seven receives reduced incoming headshot damage, as do Mo & Krill, who have a separate hitbox for each of Mo and Krill's heads.

Spreadshots

Spreadshots are a property of certain weapons that allow them to shoot multiple bullets at once, such as shotguns and shurikens.

In these particular cases, all the previous instances of damage apply to every single bullet.

There are currently 6 weapons capable of doing Spreadshots in game

Hero	Weapon	Bullets per shot	Pattern
Abrams	Case Closed Spreadshot Close Range 51 Damage Per Second Falloff Range 17m ➞ 40m Reloads single shells at a time. Can be interrupted	9	Semi-Fixed
