New Champion: Weapon Meastro
Basically, a champion who is proficient at all forms of swords, knives, etc. Would make him an ADC since he'll use mainly ranged weapons. I imagine him looking like some hybrid between a samurai and a ninja, while being pimped out with weapons strapped to em from every place he can put em. Bear with me, this might sound crazy, but when you think about how a really skilled player can make the most out of this champion you can tell it'll be cool af.
Passive: Weapon Chain: When attacking an enemy champion with a different weapon than the last it will deal 5% more damage. The buff will continue to stack until 3 seconds have passed in which a champion was not hit by a different weapon. (It doesn't matter if you hit 2 separate champions, the buff will remain unless it's been 3 seconds. Your Q W E and R all count as stacks.
Q: Knife Throw: Your auto attacks throw 3 knives at opponents in quick succession dealing 50% of your AA damage each. After throwing the knives you must wait a moment as you gather more. If your opponent leaves your auto attack range after throwing, say 2 knives, the last one won't be thrown and you'll just reload. Attack speed increases the speed of the reload. Leveling the skill decreases the window between each thrown knife. Knives can critically strike.
W: Gauntlets: Block with your gauntlets and become unable to use your other skills, but deflect melee damage back onto opponents. Your weapon chain passive is paused for the duration of the ability, so in case no one hits you, you don't just lose the chain just for that. But if you do deflect someone it counts as a stack of course. Lasts 1/01.25/1.5/1.75/2 seconds. CD: 20/18/16/14/12 seconds.
E: Quick Strike: Take out your sword and slash forward dealing damage to enemies you slice through, or dash backwards, slashing the air sending a wave of wind in front of you, but dealing half the damage of the forward slash. Range: 600 forward, 450 back CD: 14/12/10/8/6 seconds.
R: Windmill Shuriken: Throw huge Windmill Shuriken at opponents dealing massive damage. They collide with the first champion hit. You get 3 shuriken to throw, and as the skill levels that number rise to 4 then 5. Reactivate the skill within the 10 second time frame to throw the remaining shuriken. There is a one second CD between throws, and after the 10 second window, the ability goes on CD. Windmill Shuriken can critically strike.
Range: 1000. CD 120/100/80 seconds. Windmill Shuriken Count: 3/4/5
I don't know what the numbers should be exactly, but you should see what I mean by skilled players getting the most out of him. If you can properly chain your weapons you can make the most out of the weapon chain passive. His ultimate can be used in tandem with his AA's for an easy 10 stacks of his passive (At max level), but the best players can squeeze in his E and W to keep the chain going even more. CDR would be important on him, so
would be core. And since his ult can crit and attack speed increases the reload speed on his knives, a crit build would be ideal for him as well. I'd love to see a champion with a chain niche that could probably do some disgusting damage in the right hands.
