Grengon, the vile sufferer
This is a champion idea that's still in the works, with basic ideas. I'll expand more on this eventually
He's melee, and is an atrocity that simply wishes to live, despite many others wishing he'd die.
Passive: Fearful Euthanasia. 2 Parts Damaged Being: Every time an enemy unit hits Grengon, they gain a stack of damaged being. For every stack, they do 2/3/4/5% less damage to Grengon. This caps at 5 stacks, and resets after a couple of seconds of not hitting him. Fearful Euthanasia: Every time Grengon takes damage from an enemy champion, he also gains a stack of Fearful Euthanasia. After gaining 8 stacks of FE, Grengon releases a screech, fearing all enemies in a 500 unit radius (+50 for every 80 Armor or MR Grengon has) for 1.5 seconds away from him. The stacks reset after Grengon screeches, but can be immediately reapplied.
Q: Eye of the Victim Grengon grimaces at a targeted enemy unit, marking them with Culprit, and gaining 10/15/20/25/30% bonus movement speed towards them. Enemies marked with damaged being are marked with Culprit as well. The next auto attack or ability grengon does towards a target marked with culprit deals 30/60/90/120/150 (+80% AP, +40% Armor and Magic Resist) as magic damage. If the targeted enemy was already marked with damaged being before Eye of the Victim was used, the bonus magic damage is increased by 5/10/15/20/25%
W: Vile Aura Grengon's vile aura seeps out for 8 seconds, affecting all enemy units in a 500 range. If an affected enemy unit is moving, dashing, or being displaced, they'll take 10/20/30/40/50 +3/3.5/4/4.5/5% of their missing hp as magic damage every second, as well as being slowed for 10/15/20/25/10 +5% for every 10% of hp they're missing. If an enemy champion damages grengon, the aura momentarily stops for 1.5/1.375/1.25/1.125/1 second.
E: Will to Live Grengon momentarily buffs himself, increasing his Armor by 3/6/9/12/15 + (30/40/50/60/70% ) and Magic Resist by 2/4/6/8/10 + (20/30/40/50/60%) for 5 seconds. If Grengon takes damage during this, the duration of this buff is increased by 1/1/2/2/3 seconds. For every second after the 4th that this buff is still active, Grengon gains a stack of FE.
R: Terrorizing Horror. Similar to Yasuo's Ultimate, where a CC condition has to be met, Terrorizing Horror can only be casted on Feared targets. Upon using this ability, Grengon quickly leaps to the feared target and screeching, fearing all enemy units in a 450/600/750 unit radius away from him for 0.8/0.9/1 seconds, and reducing their Armor and MR by 10/20/30% for 4 seconds. Grengon can cast this ability 2 more times, fearing for the same amount of time on every fear. The Armor and Mr reduction does not stack.
So basically, the entire idea of this champion is to NOT FOCUS THE TANK. This idea is stressed throughout the entirety of his kit, however, it's done in a way that takes your enemies skill into account. I've always liked Rammus' design thematically, however, he is annoying in the game. He screams "You shouldn't fight me." but having a taunt on his kit sorta throws this idea out the window. I designed a champion that gets stronger when enemies fight him, however, there's no ability on his kit other than his W that forces you to do so.
I'd like your thoughts on what could be done to improve this idea.
