Glacial Augment

Rune Description

For 1.5 seconds, this attack slows down enemy champions by 20%. The slow occurs only once every 10 seconds for the same champion.
When you immobilize an enemy, three glacial rays will emanate from them towards you and this enemy champion, creating icy zones that will last for three seconds.
Enemies in icy zones are slowed (1% bonus carrier health +20%), and their damage against your allies is reduced by 15%. After leaving the icy zone, the slowdown effect will last for 1.5 seconds. (20 second cooling period)
