Temze

Champion name: Temze Passive: By being away from allies and out of combat Temze gets marked making it so that the next attack on him does 20% of the damage as true damage, while being near allies Temze can choose an ally to grant bonus 10% ad and ap to (This also gives him the bonus ad and ap)

Q: Temze summons the residue that caused Zilean his disease, temporarily stunning enemies near a chosen ally and dealing damage based on that persons movement speed 50%/60%/70%/80%/90% of total movement speed. While also granting his ally movement speed depending on the amount of people stunned. This ability takes 2 seconds to generate but if timed well I guess it can be used to stop someone like hecarim with his E.

W: Temze looks into the void allowing him and his chosen ally to do 10%/12%/16%/18%/20% bonus damage on their next ability or auto attack. E: Temze can shoot a skill shot at either an ally or an enemy , If it is an enemy it turns the controls of the enemy backwards and turning their screen a tint of purple as if they were looking into Temze's memories of the void, this does damage each second for 3 seconds 60/70/80/90/100 (+80% of ap) every second, if it hits an ally it suppresses Temze forcing him to channel for a second and teleport the ally to himself healing them. This ability can be cancelled early to stop it.

R: Temze focus's all of the temporal magic that brought him back and all of his void powers to make a circle giving allies inside bonus cool down reduction (10%, 20%, 30% scaling per level) and giving enemies half of it (5%, 10%, 15% scaling per level) this effect can be granted even if the user already has max cool down reduction increasing the highest possible cool down to 75%. The higher the cool down reduction the shorter the effect lasts on you, at 75% the effect will last for 3 seconds, at 5% the effect will last for 25 seconds.

I can write a full lore if you want.
