Summon Aery
Decrease Aery damage and shielding ratios by 33%.
When Aery damages an enemy champion, she turns blue.
When Aery shields an ally champion she turns red.
When red Aery damages an enemy champion the damage is doubled.
When blue Aery shields an ally champion the shield is doubled.
But why?
Summon Aery should really be a support keystone, and it should reward supports for using it.
There are many champions who take Summon Aery without any heal or shield ability.
Basically they are using Summon Aery as a guaranteed proc Arcane Comet, with a lower mechanical cooldown.
Some champions can even proc Summon Aery twice with the same ability.
isn't the same without it and Mage runes (and just Mages in general) blow ass right now.
