Champ Idea
I'm going to start off saying that I haven't thought about this a ton and just thought it would be kind of fun to post it. Right now a lot of things are un-named and the numbers aren't in place, but I tried to come up with at least a gist of the kit. If anyone actually cares to add input please do so. I feel like a lot of his kit is similar to other things already in the game, but I like the whole aura thing he has going.
Ert
Bio: Ert is a lone spirit of nature seeking to cause mischief to whomever crosses his path. His kit revolves around auras and not so much about directly attacking the enemy.
Passive: When in grass or the jungle, nearby allied champions receive increased health regen.
Q-Earthly Defense: Ert creates a shielding aura around an ally champion for 4 seconds. Once the shield is up, it decays while a portion becomes health. Cooldown: 23 / 21 / 19 / 17 / 15 Cost: 60 mana
W: Ert places an aura on the ground at specified location. Any enemy Champion in the aura has their movement speed reduced. Any Teammate in the aura has their movement and attack speed increased. Cooldown: 7 Cost: 70 / 80 / 90 / 100 / 110 MANA
E: Ert puts an aura of thorns around an enemy champion. Whenever the inflicted enemy is near an ally champion (Within 530), they take continuous damage. Cooldown: Cost:
R-Natural Vengeance: Ert forms an absorbing aura around a selected champion for 2/2.5/3 seconds. Any damage done to the selected champion while the aura is active restores health based on damage done. Cooldown: 120 / 110 / 100 Cost: 100 mana
