Crit Rate Calculator

AVOID THE TRAP

Crit rate from relics is MULTIPLICATIVE, not additive. This calculator shows your actual crit rate and how much you're losing compared to expectations. Data verified from video analysis.

Crit Rate is MULTIPLICATIVE!

Relic crit rate multiplies your base crit, it does NOT add to it. This makes crit rate relics significantly worse than they appear.

Source: Video analysis confirmed with Cyborg (15% base + 37.5% relic = 20.6% actual)

Trait bonuses add to base BEFORE relic multiplication

Calculation Formula

After Trait = Base + Trait Bonus

Actual = After Trait × (1 + Relic%)

Wrong = Base + Trait + Relic

Verdict

Your 37.5% crit relic only adds5.6%actual crit rate. Consider using a Damage or Cooldown relic instead for better returns.

❓ How to Use the Crit Rate Optimizer

  1. Input Base Stats: Enter your unit's Base Crit Rate (found in unit stats, e.g., 15%).
  2. Add Relic Bonus: Input the Crit Rate % from your equipped relic (e.g., 37.5%).
  3. Analyze the Trap: The tool calculates your *Actual* Crit Rate versus the expected additive rate, revealing the "hidden loss" from multiplicative scaling.
  4. Optimize: Use the recommendations to switch to Damage or Cooldown relics if the efficiency loss is too high.

Why This Matters

  • •A +37.5% crit relic on a 15% base unit only gives ~5.6% more crit
  • •The same slot with a +48% Damage relic gives +48% damage directly
  • •Crit rate relics are only efficient on high base crit units
  • •Use Damage, Cooldown, or Crit Damage relics instead

Recommended Alternatives

Damage Relic+48% (Additive)
Cooldown Relic-22.5% (More attacks)
Crit Damage Relic+72% (Better scaling)
Hyper Armor DMG+99% (Boss killer)
