Champ concept: Blaster Dark, the Forsaken Bladesman

Lore: There is a legendary weapon in the United Sanctuary, the mighty weapon known as Blaster Blade. It is seen as a beacon of hope, with a power fueled by the bonds between comrades. However, wherever there is light, there must be darkness. Yunos, a promising young knight in the Royal Paladins, took the test to see if he could wield the legendary weapon, only to find that it rejected him, finding him unfit to wield the power of bonds that was the base of the United Sanctuary. Instead, Yunos' childhood rival, Ahmes, took the blade and was found worthy. Unable to cope, Yunos fell into despair, which drew the attention of the mighty demon "Phantom Blaster Dragon." Phantom Blaster offered him a place in a new army, an army that rejected the ideals of the Sanctuary, and offered Yunos a new weapon, one with the capability to face off against Blaster Blade. It was the shadow of the holy weapon, Blaster Dark. Yunos took the sword and, as is customary in the Sanctuary, took the name of the blade as his own.

However, when he and his fellow Shadow Paladins went to war with the Royal Paladins, Blaster Dark and his allies realized that they had been tricked by the demon. Blaster Dark, in a moment of sadness, gave his weapon to Blaster Blade, and witnessed his old rival attain new levels of power. He swore that he would become strong enough to fight Blaster Blade on his own, wielding his own strength instead of power given to him by the demon. And then, in a shocking decision, he swore his life to his old rival, declaring that the Shadow Paladins would serve the Sanctuary until the day it crumbled.

But now his greatest ally is missing, and an increasingly paranoid Blaster Dark is left in control of a struggling faction that is going to war with itself. He has few allies left, and it was only with the aid of other clans (and some help from the very demon that led him to darkness) that he managed to defeat Claret Sword Dragon, who attempted to take Blaster Dark's position. Despite the growing threat of rebellion in his ranks, Blaster Dark stands strong with his allies, and will serve Blaster Blade- no, Ahmes- until the day he dies.

Abilities:

Passive: Emotion Engine.

Blaster Dark's signature weapon has the power of the incredibly dangerous "emotion engine," allowing him to draw from the defeat of his allies to bolster his strength Whenever an ally champion or minion dies near him, he gains a stack of "vengeance", which lasts for 5 seconds and provides him with 2/3/5/7/10% increased attack damage. A champion dying will provide him with 2/3/4/6/8 stacks depending on level, and the passive can stack up to 8 times at all levels.

Q: From the Shadows (15/14/13/12/11 second cooldown) Blaster Dark will blink to a target, and deal physical damage. He will consume 2 stacks of vengeance, if possible, to deal bonus physical damage that scales with ad. He cannot blink to a target if a unit is in between him and his target.

W: Burning hatred (20/18/16 second cooldown)

Passive: every time you gain a stack of Vengeance, Blaster Dark heals for 5% of his max health. Active: for 5 seconds, gain a stack of Vengeance each second. For 10 seconds after this effect takes place, Burning Hatred's passive is inactive.

E: Diablo (10/19/8 second cooldown)

Active: Blaster Dark holds his weapon above him, and will block the first attack to hit him for 3 seconds after this effect is activated. If he successfully blocks, he will gain a stack of Vengeance.

R: Phantom Blaster

Passive: every 10/9/8 seconds, Blaster Dark will sacrifice a random small ally minion nearby, giving gold to the last one to have attacked it in 5 seconds. Blaster Dark also gains 1% crit chance for every stack of vengeance he has at any given moment. Active: When at 8 stacks of Vengeance, consume all of them to transform into Phantom Blaster "Diablo". Your autoattacks gain increased range, attack speed, and damage, and you gain bonus armor and magic resist scaling with your ad for 10 seconds.
