Glacial Augment

Effect

Passive: Immobilizing an enemy champion will cause 3 glacial rays to emanate from them towards you and other nearby enemy champions, creating icy zones with a 700 unit radius that last for 3 (+ 100% of the immobilizing effect's duration) seconds.

Enemies within the icy zones, which have a width of 80 units, are slowed by 20% (+ 7% per 100 bonus AD) (+ 6% per 100 AP) (+ 9% per 10% heal and shield power) and have their damage reduced by 15% against your allies, excluding yourself.
