Nunu Rework
Passive: Every five attacks, Nunu will launch a snowball at target enemy, dealing bonus magic damage and slowing them by 15% for 1.5 seconds. Every successful ability, Nunu leaves a stack of 'Hypothermia' on enemy champions; Stacking upto 5 times. Hypothermia stacks last for 10 seconds, scaling on the enemy champion's current level.
Q: Active: Nunu launches an ice shard at target enemy, dealing bonus magic damage and applying 'Hypothermia'. Nunu may reactivate this within 4 seconds for his Yeti to punch the ice shard into the enemy unit, dealing physical damage. Killing units restore a small amount of health and reduce the cool down of this ability.
W: Passive: Every 10 basic attacks, Nunu may consume smaller enemy units; Granting him a permanent increase in movement speed, and 2% maximum health. Active: Nunu may warm the blood of him and his allies in a small area, giving them bonus attack speed for a short duration.
E: Active: Nunu forces his yeti to barrel forward in a target direction, dealing damage to all enemies hit. Enemy champions caught in this path may be pinned against terrain, and stunned for 1 second.
R: Passive: Nunu and his Yeti are engulfed in a snow storm passively, blinding enemies who stand near him for a prolonged period of time. Also, giving those enemy champions a stack of 'Hypothermia'. Active: Nunu engulfs himself in ice for upto 1.5 seconds, blocking all damage dealt to him for this duration.
