Understanding Battle Power

How the game adds up a hero's BP: its formula, checked against 748 heroes.

BP = (Hero + Gear) × Skills

Battle Power is three things multiplied out: the hero, everything added on top of it, and a skill multiplier applied to both.

Part 1

The hero

Only the hero's level-1 stats count. Each one is multiplied by a weight for that stat and a correction for the hero's class. Level, sublimation, stars and awakening never add stats here: they only raise the multiplier on that small sum.

Class correction

The same stat counts differently per class. DEF weighs over four times as much on a Marksman, Mage or Healer as on a Defender, so squishy heroes are not punished in BP for low defences.

Gear and everything else

Everything on top of the hero counts as gear: equipment (main stat, unlocked sub-stats, set bonuses), the artifact (level stats, refine and dark stats), the account's faction collection rewards and any skin bought for the hero. Each hero has its own weight per stat, and a % stat counts as the flat stat it adds on that hero, so ATK% is worth more on a hero with high ATK.

ATK is worth something different on every hero

BP per point of ATK from gear, for every Legendary. The same +1,000 ATK adds 600 BP on Aedrin and 3,067 on Beelzebub, before skills. Most of it comes from the class: every Legendary Marksman shares one weight, and only a few heroes get their own.

Skills multiply everything

Every skill that counts adds a share to one multiplier, and that multiplier applies to the hero and the gear together. It grows with skill levels, sublimation passives, a fetter partner, the artifact's skill and some equipment effects.

Each line changes one thing on the same Hex (123,973) and recomputes with the game's own formula.

Things that surprise people

  1. 1A skin counts even when it is not worn.Owning a bought skin adds its stats to BP whatever the hero wears (100 on this Hex).
  2. 2Two identical heroes can show different BP.Faction collection rewards belong to the account, not the hero: 1,211 here.
  3. 3Some skills need another hero.Hex's fetter skill only counts while you own Twyla: +7.5% on everything.
  4. 4Exclusive artifacts beat Mythic ones on BP.Same level-25 stats, but the exclusive skill adds 21% at stage 5 against 17% for a Mythic.
  5. 5The same gear is worth different BP on each hero.A point of ATK is worth 0.60 BP on Aedrin and 3.07 on Beelzebub.
  6. 6Crit can be worth nothing.Crit Rate and Crit DMG add no BP on Aylin, Carnelian, Constance. Crit Rate also stops counting at 100%.
  7. 7Sublimation is the biggest lever after gear.Going from sublimation 0 to 6 adds 43,101 on this Hex: a bigger multiplier and two skill passives.
  8. 8Rares level up harder than Legendaries.At level 60 the level multiplier is +5.518 for a Rare and +4.965 for a Legendary.
  9. 9Some basic attacks never add BP.On 15 Epic and Legendary heroes (Ai, Aveline among them) the basic attack can't be levelled, so it counts at level 1 and adds nothing, where Hex's adds +5%.
  10. 10The BP List is one build.Its awakening columns step up by exactly 1.70× the hero-part gaps: measured on one account's gear and skills, not a property of the hero.

Work it out for any hero

Pick a hero and an investment. This is the game's formula with no equipment, and it matches the game to the point.

No equipment, faction collection or skins: those depend on the account. For each hero's BP with the best gear for BP, see BP Potential.

How accurate this is

The formula matched the BP the game shows for all 748 heroes on our test account. The calculator above matches the game's no-gear BP in 1,476 out of 1,476 hero and awakening combinations.

Every hero's BP at full investment, and the stats that raise it most: BP Potential. The community-measured numbers stay on the BP List.
