Some people really liked this champion so I decide I would post it :P.
This guy didn't take as much thought as DhaMa so he might be pretty rough.
This is Kit, the Silent Stroke. He is a fox ninja with a giant inkbrush. He is mute so he communicates through ink writing.
AD Top Bruiser
Passive: Ink Mark. Every third hit, the enemy's screen is darkened for 1 second. (Grave's smokescreen, Nocturne's Paranoia)
Q: Ink Wash. Shoots a cone of ink. Slows enemy and also applies an ink mark.
W: Calm Seal. Kit paints a circular symbol on the ground. All enemies within the circle are silenced and applies an ink mark. Allies within the circle gain a defensive boost.
E: Fox Flash. Instant dash in a line. All enemies in path take damage. (Fox McCloud's Side-B in Smash)
R: Black Script. Draw a path with your mouse (within a range). After clicking R again, Kit will become untargetable and dash across this path, painting a giant ink drawing. Any champion in the ink are silenced, and their Ink mark is activated.
(My skillset ideas are trash XD.)
