The new champion Syndra in League of Legends uses a skill named Dark Sphere to place these cool balls of anti-matter on the field. The balls last for 6 seconds and the cooldown of the ability only easily allows for 2 balls on the field at a time. This is important because her ultimate spell, Unleashed Power does more damage based on the number of balls on the field at the time of cast.
Now her second ability Force of Will allows her to grab a ball, refresh its duration to 6 seconds, and throw it at something. (In that order)
Now I have cleverly managed to get 3 balls on the field at any given time but the wiki strongly hints that there can be 4.
How many balls can I have and whats the spell order \ CDR requirments to achieve them?
