They're not flavor text... I realized luck is used for the distribution of critical stars. If you have a servant with A+ luck and another one with B luck, almost all of the critical stars will go to the cards with the A+ luck. This is just guessing, but I think strength is buster card effectiveness, MP is for Arts effectiveness, and Agility is Quick card effectiveness. NP should be the Noble Phantasm Usefullness or the increasing bar rate (a high NP parameter will have easier to fulfill the 100% bar for example) and endurance I don't know 🤔
