Fire Rate

Fire Rate, also known as Bullets per second, is a stat that determines the amount of ammo that will be fired by the weapon per second. Several heroes have abilities that can increase their fire rates to shoot faster, but it can also be decreased, primarily through other enemy's items.

The inverse of this is called gun cycle time, which instead measures seconds per bullet.

Math

The final Fire Rate change is calculated with separate rules for bonuses and slows: positive bonuses (buffs) are additive, while negative bonuses (slows) are multiplicative.

It is important to note that the total change to Fire Rate cannot be reduced below -50%. Any calculated value lower than this will be capped at -50%.

The overall formula is: $\text{Fire Rate Modifier}=(\text{All Bonuses Added})-(1-\prod (1-\text{Slows}))$

Where:

• All Bonuses Added = Bonus1 + Bonus2 + ... (e.g., 0.25 + 0.20 = 0.45)
• $\prod (1-\text{Slows})$ is the product of the remainders for each individual Fire Rate Slow (e.g., (1 - 0.25) * (1 - 0.35))

Examples

Combined Bonuses and Slows

For an example with multiple sources:

• +25% Fire Rate from Ricochet
• +20% Fire Rate from Swift Striker
• -25% Fire Rate Slow from Sinclair's Vexing Bolt
• -35% Fire Rate Slow from an enemy's Suppressor

The calculation combines the additive bonuses with the multiplicative slows: $(0.25+0.20)-(1-(1-0.25)\times (1-0.35))$
$=0.45-(1-0.4875)$
$=0.45-0.5125=-0.0625$

This results in a -6.25% final change. The in-game UI typically rounds this value to the nearest whole number, displaying -6%.

Maximum Slow Reduction

For an example with only slows applied:

• No positive Fire Rate bonuses
• -25% Fire Rate Slow from Sinclair's Vexing Bolt
• -35% Fire Rate Slow from an enemy's Suppressor

The calculation is:
$0-(1-(1-0.25)\times (1-0.35))=-0.5125$

This results in a calculated slow of -51.25%. Due to the cap, this value is raised to the maximum reduction of -50%.
