How Glacial Augment works
Inspiration · KeystoneGlacial Augment: immobilizing a champion fires 3 rays that create zones slowing enemies 20% (+scaling) and cutting their damage to your allies by 15%; 25s cooldown.
- The zones last 3 seconds plus the duration of the immobilizing effect, so longer crowd control produces longer frozen zones.
- The slow scales with heal and shield power, ability power and bonus AD, while the 15% damage reduction protects allies but not you.
- Fits supports and peel champions with reliable immobilizes who want to shut down an enemy carry diving their team.
