[Champion Concept] Khyrus, the Nightwalker
Background Khyrus is a feared assassin of Ionia. I don't know if it's canon, but I've seen mentions of the "Black Lotus" since Jhin's release, should it be canon, that'd be her affiliation. Khyrus would primarily be a jungler but it wouldn't be uncommon for her to hop in a lane. Her identity would be hard cc at a distance with high-risk, high-reward soft cc CQC. Her role is not intended to be an AD assassin given her title. Her identity in Runeterra would be a royally hired assassin, similar to Jhin's occupation. She is a respected rival to the Du Couteau's.
Stats Health: 576 - 1943 Health Regen: 8.2 - 17.1 Attack Damage: 64 - 117 Attack Speed: 0.71 (+0% - 53.2%) Armor: 27 - 85.5 Magic Resistance: 32 - 53 Movement Speed: 350
Asphyxiation, Passive Khyrus' blades are secreted in a paralysing toxin. Her first and third basic attacks on a target deal bonus 20/40/60 magic damage and slow by 30/40/50 for 1.5 seconds. Enemies hit by a fifth basic attack are rooted in place for 1 second. Slow does not refresh on the same target. Asphyxiation stacks can only be applied to the two most recently damaged champions. Stacks reset after 4 seconds of not being hit by a basic attack. Bonus magic damage is doubled against minions and monsters.
Lockdown, Q Cooldown: 14/13/12/11/10 Mana: 60/65/70/75/80 Tether-like skillshot Khyrus throws her weighted chain in a line, stopping at the first enemy struck. If Khyrus catches a champion, during this time Khyrus and her target are rooted until the duration is over, holding her and the captured target in place. Enemies struck are dealt 60/75/90/105/120 + 0.6 AD. Upon capture, she tightens the chains around them disrupting channels and locking them in place dealing 30/45/60/75/90 + 0.3 AD bonus physical damage.
Range: LeBlanc's Ethereal Chains
Eventide, W Cooldown: 18/17/16/15/14 Mana: 70 Skillshot Dash Khyrus quickly rushes in a direction dealing 70/90/110/130/150 + (0.6 AD + 0.4 AP) as physical damage to any enemies struck applying on-hit effects. In the next second, this can be casted again if she strikes a champion. Eventide cannot crit nor apply Asphyxiation to multiple targets.
Range: Similar to Renekton dashes. Missile speed similar to Irelia Q.
Sister Moon, E Passive: Allied Khyrus' faithful raven, Nox, assists her in battle. Damage Nox deals applies a 3/6/9/12/15% life steal for Khyrus while in Khyrus' area of influence. If Nox dies, Khyrus is enraged and deals bonus 20/35/50/65/80 physical damage to her targets for the next 8 seconds. Nox is a pet and can be controlled manually. Nox is respawned at Khyrus' side after 30/27/24/21/18 seconds.
Active: Bird's Eye Cooldown: 28/27/26/25/24 Mana: 50 Khyrus sends Nox to a targeted location. Nox will circle the location granting true vision in her target area. Nox's death will still enrage Khyrus regardless of location.
Range: 3000/3250/3500/3750/4000 units
Cat's Cradle, R
Khyrus plays her trump card and curses an area around her for 6/7/8 seconds. Khyrus reduces her resistances by 40/35/30% in exchange for brief invisibility after casting Eventide, 30/35/40% increased movement speed, and attack speed for both her and Nox. Asphyxiation's bonus damage is doubled and Khyrus' abilities lacerate her targets making them bleed for 100/150/200 physical damage over 3 seconds. No outside forces can interfere with players inside the field. Enemies cannot escape Cat's Cradle.
Range: Self-cast, roughly the size of Kindred ult.
Use this ability to punish enemies caught-out. Primary use; killing the punished enemy. Secondary use; trap a group of enemies for the duration
