In upgrading Parasite Weave Filia's Skill tree (Crit Rate - Increases Crit Rate by 10%), it shows: 100% -> 100%. Not sure why this happens... but the maths does not make any sense? Don't know whether I should buy this "upgrade" or not. Kind of feels like the Painwheel "Upgrade" to her fly move but makes her 10 times weaker because you keep flying but can never ever use an air combo ever again. This crit rate upgrade might mean I never crit again?
