Glacial Augment is the rune for champions who have problems keeping up with their enemies. Regardless of if you are playing melee or ranged, Glacial Augment should help keep you from getting kited around. If you use any kind of active item with a slowing effect, like Blade of the Ruined King, you even get an extra bonus.
What does it do?
Basic attacking a champion automatically slows them. The slow increases as it goes on and lasts for two full seconds. This effect has a seven to four second cooldown per unit. The slow is more powerful for melee champions but also works for ranged champions. If you use an active item to slow a champion, a extra ice beam creates a slowing field in a line extending from your initial target.
Which runes go well with it?
Glacial Augment is for all of our friends with little to no CC. Alternatively, this is a decent choice for champions that only offer hard CC and struggle to keep champions locked down when their abilities are on cooldown.
Perfect Timing is going to be the rune of choice for Glacial Augment. Almost any champion who plans on grabbing Glacial Augment will be building a Gargoyle’s Stoneplate, Zhonya’s Hourglass or Guardian Angel. Perfect Timing will just make that process cheaper and give some extra sustainability in lane.
Magical Footwear will give us free speed at 10 minutes. Since we’re trying to move as fast as possible and keep up with our enemies, more powerful boots just makes sense. Approach Velocity will improve our stickiness even more. We’ll always be impairing enemy movement with Glacial Augment, so Approach Velocity will almost always be active.
We’re taking Domination as our secondary tree. This is mostly for Cheap Shot, which increases our damage against any and all movement impaired champions. Eyeball Collection will just become some extra power as we move through the game.
Who’s it for?
There are lots of League champions who need a little help in the stickiness category. If you’re pretty slow, can’t keep up with your foes or just want to be even more annoying to play against, Glacial Augment is for you.
You want to take this rune on champions like:
Jax and Darius both struggle to keep up with their enemies. While you may be able to do a ton of damage, it doesn’t matter if your bait always gets away. Glacial Augment is perfect for fixing this. Zoe on the other hand actually has some CC, which is nice. But since she has all those weird active item grabs, she is able to take advantage of the ice beam frequently. It will also making hitting her long range Q much easier.
