Some ideas for glacial augment secondary effect
"PASSIVE – FREEZE RAY: Slowing an enemy champion with an item active triggers your Freeze Ray to fire a laser that cuts an X-unit line through the ground in their direction, creating a slowing field for 5 seconds that Slow icon slows units inside by 50%. The Freeze Ray can fire upon any number of champions concurrently, and has no cooldown."
Glacial augment's main effect is definitely a fun and useful keystone but it is usually outclassed by other keystones due to it not adding any damage as well as the tree that this is located in, so many people who take this keystone are usually the ones that can also capitalise on its secondary effect as well. I had an idea where if it was possible for riot to extend its secondary effect to trigger on the use of summoner spells that have slows built into them (ie exhaust and chilling smite) so that this keystone could be more viable on a wider range of playstyles.
More supports can make use out of both the primary effect to harass with autos and apply a slow to help their ADC trade with who you auto, and now supports that take exhaust can create more of a zoning effect with their exhaust for slowing multiple enemies for either engaging or retreating while also having the option to use their exhausts to reduce damage output (as exhaust is usually used for earlier in lane.) In addition to this, junglers who take chilling smite to make ganking easier will get extra use out of glacial augment to make chilling smite better at ganking botlane for example or for later team fights where generally having other keystones would be better than glacial augment (I cant say for certain how this change will affect junglers as I mostly play botlane so I'll leave that for the discussion down below to someone who knows better.)
TL;DR: Make glacial augment's secondary effect proc on summoner spells that have slows to open this keystone up for more supports and junglers.
This is my first time ever making a post on the league of legends forum so any constructive criticism to either the format of my post or the post itself is more than welcome :)
Edit: talking to alot of people, I have found another big issue with glacial augment that has nothing to do with the effect of the keystone at all. Most of the community thinks that this keystone is specifically designed as an alternative to champions that generally buy frozen mallet or iceborn gauntlet, allowing said champions to circumvent buying those items. I personally believe this is NOT the intent of this rune in any way, shape or form. This rune was designed such that champions that would like the passives of either of these items alot but it wouldn't make any sense to get these said items on these champs. Feel free to discuss the use of this rune down below if you do wish. personally i think this issue comes from the name as well as how the keystone sound's like its going to be like or how it suppose to be used and thats the mentality most people are going by when considering this rune.
