Hardened parry timing demands inputs
Stellar Blade
Parry and perfect-dodge timing windows define the ceiling
Reads1 vs 1
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.

Bosses run fixed movesets, learnable not adaptive

Shell choice and upgrade routing matter
Stellar Blade
Exospine builds, gear and moveset study reward preparation
