Beast of Reincarnation Damage Calculator

Q: Should I use additive or sequential stacking?

If you have not tested the stacking rule, calculate both. The gap between the results is the uncertainty introduced by that unknown rule.

Q: How should I enter target defence?

Do not invent a defence value. Test an unmodified hit on the same target and leave target damage taken at 100, or enter a multiplier you measured independently.

Q: Does the calculator include defence penetration?

Not directly, because the game’s defence and penetration curve is not published. Their effect can only be represented through a target multiplier derived from a controlled test.

Q: Where do the modifier presets come from?

Each preset is a value read off a specific documented build, and the page names which. They are sourced worked examples, not universal best-in-slot advice.

Compare Beast of Reincarnation damage modifiers from an observed hit, with additive and sequential stacking models, critical weighting, target multiplier and a visible calculation breakdown.

Use this to compare controlled observations, not to predict an unknown tooltip from raw stats. Beast of Reincarnation’s defence, penetration, PvP scaling and per-skill coefficients are not publicly documented, so none are silently guessed here.

Inputs

Start from a damage number you observed

Observed normal hitRead this from a repeatable test against the same target.Hits in the comboUse equal-damage hits; calculate mixed-hit combos in separate passes.Attack bonus %Example: Valor T5 is +7.5% attack in the sourced build.Skill-specific bonus %Enter only a value shown by your tooltip or controlled test.Conditional / execution bonus %Example: Burst T5 is +25% execution damage.Critical chance %Set 0 to compare non-critical output only.Critical damage % of normal150 means a critical hit deals 1.5× the normal hit.Target damage taken %Leave at 100 if the observed hit already includes this target’s defence.

Bonus stacking model

Nobody has published which model the game uses. The difference between them is shown alongside the result so you can test it against your own hits.

Model disagreement

The two stacking models differ by 0 on these inputs — about 0.00%. The larger your bonuses, the more the choice matters.

This does not model hidden defence, penetration, rounding, PvP scaling or per-skill coefficients. Those formulas are not published. Keep the target and test conditions identical when comparing two builds.
