Alexandrios, the Harvester (champ concept)
I'm actually quite surprised no champ uses a scythe yet (THAT DOESN'T COUNT, FIDDLESTICKS). So I figured, why not? Anyways, here's the concept:
Abilities:
Passive: Death's Reach Upon auto-attacking an enemy champion with 25% HP or less, Alexandrios dashes to them. The same champion cannot be dashed to within 10 seconds. When Alexandrios deals damage to an enemy champion, he applies a stack of Death's Grasp. Upon 5 stacks of Death's Grasp, the enemy gains Unstoppable Rampage for 4 seconds. When Alexandrios auto-attacks a target with Unstoppable Rampage, he will dash to them. The target has no dash cooldown.
Q: Shadow Charge Alexandrios charges his scythe with shadow. His next auto-attack will deal an extra (insert damage here) physical damage, and be ranged.
W: Vicious Slashes Passive: Alexandrios' auto-attacks apply a stack of Rending Strike and deal an extra (insert damage here). Upon 3 stacks of Rending Strike, Alexandrios gains 25% attack speed and attacks against the marked target deal an extra 10% true damage. Active: Alexandrios marks a target, instantly applying 3 stacks of Rending Strike, dealing (insert damage here) magic damage and gaining 35% attack speed.
E: Soul Breaker Alexandrios does a deadly strike his against target. This fears the target for 1 second and deals (insert damage here), while applying 2 stacks of Death's Grasp.
R: The Harvesting Alexandrios chokes his target, and lifts them up into the air. He slashes them 5 times, fully applying Rending Strike and Death's Grasp, applying on-hit effects and dealing (insert damage here) physical damage.
Quotes:
Pick: "The grand harvest begins now, summoner."
Moving: "I feel death in the air" Moving: "Take me to their demise, summoner." Moving: "I hunger for blood." Moving: "I am beyond redemption." Moving: "I will tread upon their corpses."
Attacking: "My blade hungers!" Attacking: "Fall at my feet, mortal!" Attacking: "Join all who have fallen at my scythe!" Attacking: "You. Will. Break." Attacking: "The harvesting shall come!"
Killing: "As prophecy foretold!" Killing: "Muahahaha!" Killing: "None can stop the harvesting, and none survive it!" Killing: "The scythe's grasp, you will not escape!"
Dying: "The harvesting.... comes to an end..." Dying: "A worthy... opponent..." Dying: "(Alexandrios screams in agony.)"
Taunt: "Come on, send more hunters for me. More souls for the blade." Taunt: "Hunted by my own... betrayed by my own... they. Will.. PAY!"
Taunt Against Zed: "Zed, be aware of what you control. Do not let the shadows corrupt your mind."
Joke: "Sometimes it gets lonely being hunted by anyone and everyone. Only one I can talk to is my blade. Hey, knock knock!.. ugh." Joke (connected to other): "I suppose there is always rocks. (Alexandrios picks a rock, carves a face into it) Hey man, you, hehe, rock!"
In a civilization long past, there was a rank known as Blademaster. Alexandrios was absolutely determined to achieve this rank. Through training and heavy meditation, Alexandrios quickly passed the ranks. After two years of hard work, he achieved the honorary title of Blademaster. However, one day while traveling with a small group, looking to begin a new city which would later be known as Noxus, Alexandrios visited a shrine. Little did he know, that shrine was corrupted. He heard whispers throughout his mind. They told him to lay his grand scythe upon the shrine. They said it would give him strength unimaginable. He did so. Upon him laying his scythe on the accursed stone, he passed out. He awoke, feeling notably more powerful. However, the corruption spread throughout his body. He had become the Harvester of Death. His plate armor had become runed with dark sigils, and had turned deathly black. His scythe had the same done to it... except for one thing. Nothing living surrounded him. He glanced at his scythe. There were skulls on a pike, now embodied in the scythe.
Fortunately, the survivors carried on and created the grand city now known as Noxus. However, the Harvester of Death, Alexandrios still lurks in the shadows.
