dmgx

Converts an amount of resist to a Damage Multiplier.

import { dmgx } from "@lolmath/calc";
 
dmgx(resist)

Arguments

  • resist (Number): The amount of armor or magic resist.

Returns

(Number) The damage multiplier.

Examples

const resist = 100; // 100 armor
const dmg = 100; // 100 damage
const result = dmgx(resist); // 50 damage

lethalityx

Calculates the multiplier to be used for lethality to armor penetration conversion.

import { lethalityx } from "@lolmath/calc";
 
lethalityx(lvl)

Arguments

  • lvl (Number): Current champion level

Returns

(Number) The multiplier to be used for converting lethality to flat armor penetration.

Examples

const lethality = 100;
const level = 13;
 
const armorPenFlat = lethality * lethalityx(level); // ~88.9

postReductionResist

Calculates the resist after all reductions and penetrations have been applied.

More Info

Magic penetration and magic resist reduction work exactly like armor penetration and armor reduction. penetration and reduction are considered on the target champion in the following order:

  1. Reduction, flat.
  2. Reduction, percentage.
  3. Penetration, percentage.
  4. Penetration, flat.

import { postReductionResist } from "@lolmath/calc";
 
postReductionResist(resist, flatReduction, percentReduction, percentPenetration, flatPenetration)

Arguments

  • resist (Number): The initial magic resist or armor.
  • flatReduction (Number): Flat reduction of magic resist or armor.
  • percentReduction (Number): Percent reduction of magic resist or armor.
  • percentPenetration (Number): Percent penetration of magic resist or armor.
  • flatPenetration (Number): Flat penetration of magic resist or armor.

Returns

(Number) The resist after all reductions and penetrations.
