250 Stacks: 10% increased ability power and 25% bonus cooldown reduction.

Additional Information:

The facing direction of champions whose abilities/animations cause them to spin is always the direction they are moving in. In the event of abilities that cause the champion to spin on the spot, such as Katarina's Death Lotus, it will factor the direction they were facing on-cast.
Lucian is facing in the direction he is moving during The Culling, not the direction his model is facing.
