the number of balls she can use for ult is infinite, as you may have seen when all-for-one mode was online.

her Q cd is fixed at 4sec, 80% reduction reduces that to 0.8 sec. balls last for 6 seconds. so you can summon a maximum of 7 balls + 3 balls orbiting syndra = 10 total for ult :D

i hope my math was correct..
