Base Reduction
1 - 1000/(1000 + Defense)
Penetration Effect
1 - (Penetration/Defense)
Final Reduction
Base × PenEffect (min 0.3%, max 95%)
The exact formula and interaction between penetration and defense has not been officially confirmed by the game developers. However, the formulas used in this table provide a good approximation.
