Damage Calculation Formula Guide
By Keripo.
Crits
Non-crit hit dmg:
Regular Hit Dmg = Attacker ATK * Skill Multiplier - Target DEF
Critical hit dmg:
Critical Hit Dmg = (Attacker ATK * Skill Multiplier - Target DEF) * Crit Dmg
Like with most games, Crit Rate is chance-based. The higher your Crit Rate, the more likely you’ll land a Critical hit. Ideally you want 100% crit rate or as close to it. Anything above 100% crit rate doesn’t actually do anything (unless you have a 5-star Asura who converts excess crit rate to crit dmg)
For PvE, if you’re thinking about “average damage over time”, to maximize your DPS, you actually want to aim for a balance between Crit (Rate) and Crit Dmg – 100%. For example, 75% Crit + 175% Crit Dmg, 100% Crit + 200% Crit Dmg, etc. For PvP, you want to get as close to 100% Crit as possible to ensure you crit.
In PvP:
Critical Dmg = Max ( Regular Hit Dmg, Critical Hit Dmg )
Effective crit rate = Crit Rate - Crit Rate Res
Effective crit dmg = Crit Dmg - Crit Dmg Res
This means that if you stack Crit Res or Crit Dmg Res, you can effectively make all their crits hit the same as regular hits. In other words, aim for 50%+ Crit Res or 50%+ Crit Dmg Res on your tanks. To counter this, focus on increasing your base ATK
Amour Pen
Penetration damage is actually dealt as a separate additive hit:
Pen Dmg = (Attacker ATK * Skill Multiplier * Armor PEN) - (Target DEF * Endurance)
Both DEF and Endurance contribute to reducing Armor Pen dmg. Contrary to in-game description, Armor Pen has nothing to do with shields. Derp.
Crit vs Pen
Depends on your unit’s skill effects. Crit and Pen are calculated separately and independent of each other (e.g. increasing your crit/crit dmg won’t affect your Pen dmg).
For DPS that deal Sunder Dmg, focus on Crit Dmg over Armor Pen. For DPS that deal Jab Dmg, focus on Armor Pen.
For attacks that are neither, you can use this handy reference:
Total Dmg = Regular/Crit Hit Dmg + Pen Dmg
Non-Crit Dmg = (Attacker ATK * Skill Multiplier - Target DEF)
Crit Dmg = (Attacker ATK * Skill Multiplier - Target DEF) * (Crit Dmg - Crit Dmg Res)
Pen Dmg = (Attacker ATK * Skill Multiplier * Armor PEN - Target DEF * Endurance)
Because ATK and DEF are multiplier for all 3 components, its never bad to go ATK/DEF. But for Sunder/Jab Dmg units, prioritize those.
DMG Modifiers
Some units such as Asura Forest Ranger, Echo Perfect Pitch, and Shiro Combat Maid have a modifier attached to their skills. Skills with these modifiers will 2x the respective base values when doing the damage calculations.
- If you have 150% crit dmg, it will be calculated as 300% crit dmg for attacks with the Sunder modifier. Note that Asura’s excess Crit -> Crit Dmg is added on to this after the 2x, not before.
- If you have 75% armor pen, it will be calculated as 150% armor pen for attacks with the Jab modifier.
- If you have 75% crit rate, it will be calculated as 100% crit rate (capped at 100%) for attacks with the Savage modifier.
- If your target has a debuff applied, skills with Dire modifier will have its regular hit dmg multiplied by 2.5x.
Luck
Luck is a crap stat. It gives your units a chance to spawn 2-star cards instead of 1-star cards. While this sounds amazing, its a multiplier against a very low base (from testing, its 5%). Even if you roll full Luck and get +100% luck, you are still gambling against a 10% chance of a card upgrade. Way too RNG to be reliable. Just don’t do it.
RNG Factor
There is a +/- 5% RNG factor in all damage calculations. This is why your numbers will vary a bit.
