Temze The Urtistan Lancer
Champion name: Temze the Urtistanian Lancer
Attack range: Melee
Playstyle: Temze is meant to be played as a tank engager similar to that of Jarvan 4, but also along with his kit Temze can be played in a variety of lanes ranging from top lane with his ability to engage and sustain or in a lane such as support where he can disengage and shield his ADC.
Passive: After being out of combat for 3 seconds Temze will empower his next autoattack, causing it to cleave all enemies in front of him for 5% of their max health as true damage. Every time Temze kills a unit the cool down on this ability is decreased by one second.
Q: Temze stabs all enemies in his way and pushes them in any direction of his choosing, this ability does 50/100/150/200/250 damage plus 40% of Temzes AD and. This ability has a 12/11/10/9/8 second cool down
W: Temze shields himself and an ally of his choosing for 2 seconds, while the shield is active Temze and the allied champion gain 15% bonus attack speed. This ability shields for 50/100/125/150/200 plus 60% of Temze AD. This ability has a 7/7/6/5/5 second cool down
E: Temze dashes in a target direction with his lance pointing out in front of him, enemies struck by this ability are slowed by 30% for 1.5 seconds and take 10% of the damage they receive within 2 seconds of being stabbed as bonus bleed damage. This ability does not do damage by itself . This ability has a 10/10/9/8/7 second cool down
R: Temze summons his horse Sleipnir and rides down a lane with or without one ally doubling Temze movement speed, Temze has complete control over Sleipnir's movements and any enemies struck with Sleipnir are stunned for 1 second. The ally on Sleipnir can get off at any point by using a movement control. This ability has a 115/90/70 second cooldown. If hard CC'd during this ability Temze jumps off Sleipnir landing with a massive explosion slowing nearby enemies for 70% for 2 seconds, if uninterrupted this ability will last 7 seconds.
I can write a full lore if you would like and am open to ideas on how to balance this fictional champion.
