Lethality, Attack, Defense & Health - What They Actually Do

Overview

This is the final version of my explanation of the damage formula. With the new findings, the battle simulations are now almost 100% accurate — so we can finally say that we've figured out the real damage formula for the game. You can see it in action on th...

• Attack and Lethality have the same impact since they multiply together. That means Lethality isn't stronger or more important than Attack — both matter equally
• Your Attack × Lethality is divided by the enemy's Defense × Health, so the old idea that "Attack reduces Defense" and "Lethality reduces Health" was completely wrong

Skill Mod or "Damage Coefficient"

This part is really important because it's what controls how joiner skills affect your damage. The formula is: In the backend (for joiners), both Attack and Lethality buffs are treated the same → they're just DamageUp effects. The "attack" vs. "lethality" w...

Why Different Joiners (Amane + Chenko) Deal More Damage

When you stack identical joiners, their buffs just add up. But when you stack different joiners, the buffs multiply instead, giving you slightly more damage. Example 1: Four of the Same Hero (Amane or Chenko, each 25%)

Result

That's a 12.5% relative increase in damage just from mixing heroes

• Four identical heroes → 2.0 (100% boost)
• Two Amane + Two Chenko → 2.25 (125% boost)

Why This Happens

The math.prod function multiplies each unique effect op separately

• If all heroes share the same `effect_op`, their buffs just add together
• If they have different `effect_ops`, the buffs compound multiplicatively → leading to higher damage

Attack vs. Lethality — Which Should You Boost?

Now that we understand the Kingshot damage formula, we know that Attack and Lethality multiply with each other. This means boosting the lower stat between them gives you a bigger increase in overall damage. In most cases, your Attack is much higher than you...
