Critical star absorption determines how likely critical stars would be gathered by a servant. The higher the number, the likelier the stars will be absorbed.

Okita has the lowest star absorption among all Sabers at 98, by levelling weak constitution, the chances of her gathering critical stars are higher, therefore her crit chances would be higher. However it only lasts for one turn so its advised to level that skill last, and only use that skill if she has a brave chain for maximum effect. Equip Bazett CE if you're worried about other servants stealing Okita's stars and that's it, not much benefit levelling that skill tbh.
