League of Legends Reforged Rune: Glacial Augment
Glacial Augment
Immobilizing an enemy champion will cause 3 glacial rays to emanate from them towards you and other nearby enemy champions, creating icy zones that last for 3 (+100% of the immobilizing effect's duration) seconds.
Enemies within the icy zones are slowed by 20% (+7% per 100 bonus attack damage) (+6% per 100 ability power) (+9% per 10% heal and shield power) and have their damage reduced by 15% against your allies, excluding yourself.
Cooldown: 25 seconds

Tip: When you have the rune equipped the game will add an "Active Slows" box to the recommended purchases (similarly how it does with Masterwork Items for Ornn) which will have every item that is affected by Glacial Augment.
