so i was thinking how Nasus staff would work in a practical way (but still sci-fi)
the way he gets stax... I could see it absorbing an entity to use its static inertia to generate a small charge based on its general size (mass ppm). so like, you take the staff and press the stack button on an apple (example), and it instantly removes all empty space of the object and condenses it into a VERY SMALL pill that vibrates. the vibration it generates makes the staff basically wobble in the slightest degree only visible in an enhanced atom view. the pill (the stack) would drop into its designated spot on the staff as if loading a bullet into a clip. so for every stack/pill/bullet the staff has, its voltage would increase because of the generated energy from the object obtained.
TLDR; i think the staff could only hold so many stax. but this theory is plausible no?
