[NEW CHAMP] G'Krlnp, the Old One
I wanted to design a mage/sustain-tank. He wants to get in the middle of everyone to utilize his passive, but he needs some ability power and defense to be effective and survive. Corruption is his gap closer, because a corrupted enemy is a new kind of helpless and fragile. This champion is greatly weakened by tenacity on his opponents, but he should still feel useful.
He will be mana-based, but I have not worked out costs yet. His goal is to close on a corrupted target while they are being tortured with sadism, then devour their soul to replenish his own health while crippling his target's sustain, and finally finish off with wrath. If he can get into the middle of the enemy team, he can severely weaken then and become extremely powerful if they don't watch their positioning due to his passive.
G'Krlnp was freed accidentally by Bard when recovering an impossibly-old relic that was being used as a prison. G'KrInp is an ancient being never before encountered by the mortal races. He was, in fact, imprisoned by the immortal Titans long before they thought to create the mortal beings that now populate the world.
G'Krlnp is one of the Old Ones, ancient god-like beings so depraved that their actions eventually split the universe, creating the Void. Weakened by millions of years of sleep and captivity, G'Krlnp craves the power he once held. To that end, he intends to devour the souls of this world's most-powerful beings and use them as a seed from which he will be able to grow a new empire of waste and destruction.
PASSIVE The Dark Speech: Enemy units too close to G'Krlnp when he uses abilities hear the tongues of the Ancient Ones, otherwise known as the Dark Speech. Mortal minds were never supposed to hear such incomprehensible evil, and it can drive even the most focused minds mad. At first, the Dark Speech is just a whisper. As his power grows, though, so does his voice. range - basic abilities trigger the passive at a radius of 140 units per level of the ability, centered on G'Krlnp. His ultimate triggers it at a radius of his highest-level basic ability (max 700) effect - hearing the Dark Speech gives a stack of Impossible Thoughts, as the reality of existence is revealed in unflinching horror to the mind of the listener.
Impossible Thoughts - 8% increased base cooldowns as the champion's mind tries to rationalize what it has just heard (max 40% at 5 stacks). Impossible Thoughts lasts for 10 seconds, reduced by tenacity, and stacks up to 5 times. At five stacks, the affected champion gains a new debuff: "Understanding"
Understanding - duration 10 seconds (not affected by tenacity) The realization of the futility of opposing the Old Ones takes hold, and the champion loses all will to struggle. This acceptance energizes G'Krlnp, entering him to do Bad Things. Every enemy champion currently affected by Understanding reduces the base cooldown of G'Krlnp's abilities by 10%. Once a champion has received Understanding, that champion cannot be gain new stacks of Impossible Thoughts or Understanding for 80/70/60 seconds.
Q - Corruption G'Krlnp infects target enemy with pure evil for the next 2/2.5/3/3.5/4 seconds. All beneficial buffs on the target are suppressed for the duration and will have no effect. If their durations are long enough, they will return to normal functionality when corruption wears off. Additionally, any self-healing, life steal, spell vamp, or regeneration on the target will have the reverse effect, taking life away as magic damage instead of adding it while the target is suffering from corruption. Corruption is affected by tenacity, and tenacity buffs are not suppressed. Life lost due to to corruption heals G'Krlnp via spell vamp. Range 600 Cooldown 10 seconds
special note - healing/regen granted by allies' buffs does not deal damage, those are just nullified
W - Sadism G'Krlnp corrupts an area with the Dark Speech, torturing all who remain in it. Range 600 Radius 350 Deals 6/7/8/9/10% + [1%/50AP] current life, rounded down (Sadism cannot kill enemies) in magic damage per second to any enemies in the affected area. Duration 6 seconds Cooldown 12 seconds
E - Gluttony Passive: G'Krlnp gains 4/8/12/16/20% spell vamp and life steal Active: G'Krlnp bites target enemy and devours a chunk of their soul. If the target has a secondary resource, 10/15/20/25/30%, rounded up, of the maximum resource amount is consumed. If not, G'Krlnp deals an additional 5/7.5/10/12.5/15% of the target's maximum life as true damage. G'Krlnp heals himself for [.6/.7/.8/.9/1] AP life in addition to the spell vamp. Range 150 (melee) Damage: ?+?AP magic damage (figuring out a good number) Cooldown 20/19/18/17/16 seconds
R - Wrath G'Krlnp screams at his enemies for a half-second in the Dark Speech, assaulting them with what was previously thought to be unspeakable evil. Enemies in a cone in front of him have their life force stripped away by the assault. Additionally, all enemies in the area are stunned for 0.5s, completely unable to act in the presence of such depravity. Range: 600 unit-long cone as wide as G'Krlnp at the start, and double his width at the end Cooldown 120/110/100 Duration 0.5 seconds (channeled) Damage 100/150/200 + .5AP at start and again at the end to anyone still in the area. If G'Krlnp's channel is interrupted, the stun ends and the second half of damage will not be dealt
