PHYS-006autoAttack

Perfect dodge always succeeds regardless of HIT/FLEE

Perfect dodge is checked BEFORE the standard hit-vs-flee roll. Tests with deliberately mismatched accuracy: extremely high HIT, low FLEE — perfect dodge should still proc at its rate. 1000 sampled attacks with seed; expect perfect_dodge count within statistical tolerance of LUK/10 + flat bonuses.

Expected output

From the scenario fixture. Numerical values marked as null are placeholders pending rAthena verification.

If perfect_dodge_percent is near zero, the perfect dodge check is either not implemented or runs AFTER the hit/flee roll instead of before it.
