Big changes on Damage Amplification and Reduction calculations. My math is very on the spot without much testing so verification is necessary. Also check all the notices I posted, I will be making a forum post on the Damage Reduction bug, and if anyone has the time, please check over my math on Total Amplification because I know it's wrong but I don't know why it's wrong. Thanks a bunch! |

'''Damage Reduction''' is a negative form of Damage Amplification, that reduces the damage output of enemies or its user. | '''Damage Reduction''' is a negative form of Damage Amplification, that reduces the damage output of enemies or its user. | ||
== Calculation == | |||
Multiple sources of abilities and items that display damage amplification percentages (e.g., +20% Damage), do not simply add together. Instead, they stack '''multiplicatively''', '''augmented'''. | |||
Multiple sources of abilities and items that display damage reduction percentages (e.g., -30% Damage), simply '''add''' together. (Though I believe this is a bug.) | |||
=== Calculating Damage Amplification === | |||
To find your '''amplification''', use the following formula: | |||
<math>\text{Amplification} = (1 + \text{A}_1) \times (1 + \text{A}_2) \times ...</math> | |||
'''Example:''' | |||
# {{HeroIcon|Drifter}} deals a base bullet damage of '''41'''. | |||
# {{HeroIcon|Drifter}}'s base {{AbilityIcon|Bloodscent}} amplification of '''15%''' will increase his bullet damage from '''41''' to '''47''' (41 x 1.15 = 47.15, rounded down in game). | |||
# {{HeroIcon|Ivy}} casts {{AbilityIcon|Air Drop}} on {{HeroIcon|Drifter}} to give him an additional '''20%''' amplification. | |||
# {{HeroIcon|Drifter}} now deals '''57''' bullet damage (41 x 1.15 x 1.20 = 56.58, rounded up in game). | |||
=== Calculating Damage Reduction === | |||
Notice: While Valve has stated in the May 22nd patch that Damage Reduction stacks '''diminishingly''', this is not true. Damage Reduction still stacks '''additively'''. Unless there was a hidden patch note, it is safe to assume that this is a bug. This means that the current formula is: | |||
<s><math>\text{Damage Reduction} = (\text{DR}_1) + (\text{DR}_2) +...</math></s> | |||
'''Example:''' | |||
# {{HeroIcon|Drifter}} deals a base bullet damage of '''41'''. | |||
# {{HeroIcon|Mirage}} casts base {{AbilityIcon|Fire Scarabs}} on {{HeroIcon|Drifter}}, reducing his damage by '''20%''', decreasing his bullet damage from '''41''' to '''33''' (41 x 0.8 = 32.8, rounded up in game). | |||
# {{HeroIcon|Mirage}} now afflicts {{HeroIcon|Drifter}} with {{AbilityIcon|Inhibitor}}, reducing his damage by another '''30%'''. | |||
# {{HeroIcon|Drifter}} now deals '''20''' bullet damage (41 x 0.5 = 20.5, rounded down in game). | |||
(Wiki admins feel free to remove this but just in case this gets fixed I'll keep it up here.) | |||
For now this is not true, but to find your '''damage reduction,''' use the following formula: | |||
<s><math>\text{Damage Reduction} = 1 - (1 - \text{DR}_1) \times (1 - \text{DR}_2) \times ...</math></s> | |||
'''Example:''' | |||
# {{HeroIcon|Drifter}} deals a base gun damage of '''41'''. | |||
# {{HeroIcon|Mirage}} casts base {{AbilityIcon|Fire Scarabs}} on {{HeroIcon|Drifter}}, reducing his damage by '''20%''', decreasing his bullet damage from '''41''' to '''33''' (41 x 0.8 = 32.8, rounded up in game). | |||
# {{HeroIcon|Mirage}} now afflicts {{HeroIcon|Drifter}} with {{AbilityIcon|Inhibitor}}, reducing his damage by another '''30%'''. | |||
# {{HeroIcon|Drifter}} now deals '''23''' bullet damage (41 x 0.56 = 22.96, rounded down in game). | |||
=== Calculating Total Amplification === | |||
To find the total '''amplification''', use the following formula: | |||
<s><math>\text{Total Amplification} = (\text{Base Damage} \times \text{Total A}) \times \text{Total DR}</math></s> | |||
'''Example:''' | |||
# {{HeroIcon|Drifter}} deals a base gun damage of '''41'''. | |||
# With {{AbilityIcon|Bloodscent}}, {{HeroIcon|Drifter}}'s gun damage is '''47''' with a '''15%''' increase. | |||
# {{HeroIcon|Mirage}} now afflicts {{HeroIcon|Drifter}} with {{AbilityIcon|Inhibitor}} and {{AbilityIcon|Fire Scarabs}}, reducing his damage by '''50%'''. | |||
# {{HeroIcon|Drifter}} now deals '''24''' bullet damage. | |||
Notice: Additional Amplifications seem to interact weirdly with this formula, I assume it's wrong. Having the {{AbilityIcon|Air Drop}} on {{HeroIcon|Drifter}} alongside the debuffs from {{AbilityIcon|Fire Scarabs}} and {{AbilityIcon|Inhibitor}} make {{HeroIcon|Drifter}}'s bullet damage 33, which is actually a 42% decrease from the amplification. Would appreciate if someone could check into this. | |||
