The way the words "direct, indirect, possibility" are used in this chapter makes me believe that a certain level of luck is taken into consideration during Bloodline grading. An example would be Jake's consumption of the liquid alloy, there must have been plenty of Kintharians that lived and died on that planet before the Digestor invasion, most if not all of them would have between a grade 6 to 8 Bloodline and the same ability to consume soul stones but perhaps only Jake's unique hybridized Aether Code allowed him to consume and digest the objects but also integrate their properties with his Bloodline. A holy trinity of his Kintherian, Eltarian and Mymidian ancestral qualities allowing him to accomplish something as astonishing as raising his own Bloodline Grade. If it's looked at from this perspective then the integration of the Beskyrian Lucky Body would grant him a higher "possibilty" of his Aether Code mutating when coming into contact with different Souls/Minerals/Forms of Aether. I don't know if being "luckier" can qualify to round out all four Aspects but it definitely wouldn't hurt his chances of achieving Grade 10 afterwards especially if he acquires a unique Soul Class in the next Ordeal with his Aether Code possessing so many incredible qualities.
