Zhen Fo - The Double Edged Sword

Hi! I just wanted to share with you one of my champion concepts and know what you think about it. All feedback and questions are welcome

Zhen Fo, the double-edged sword **Lore: **

Many warriors can wield a sword. There are many ways to use one. But few know the ancient "Double Edged sword technique" Note: (placeholder, ill change the name for a baddass-sounding japanese one later). Anyone trying to learn it must have courage and a strong mind, to be able to hurt oneself. Many people depict pain as something horrible and unwanted... But not Zhen Fo. He knows that pain puts your mind in a state of deep awareness. He knows that being so close to death makes a warrior give the best of himself. No one knows why he decided to learn such technique. Vengeance? Pride? Nobody is sure. All we know is that once his blade gets soaked in his own blood, it'll get soaked in his enemy's, too. "Pain is the key that shall open our minds" -Zhen Fo

Skills:

-(Passive) Deep Awareness: Zhen Fo doesn't use mana. Instead, he uses health as a resource. He has a "Pain" bar below his HP, which has a max of 100 points of "Pain". Zhen Fo gets a point of Pain for every 0.7% of Missing HP, and his skills get bonus effects depending on how many points he has. Also, when he gets to 100 points, Zhen Fo will cleanse most crowd-control effects affecting him and gain 50% tenacity for 3 seconds. (120 second Cooldown).

***-(Q) Shared Wound: *** Zhen Fo swings his sword twice in a quick motion, first on a half-circle in front of him and then on a half circle on his back, dealing 80/110/140/170/200(+70% bonus AD) physical damage. This damage increases by 0.6% for each Pain he has. The second slash slows all enemies hit by 50% for 1.5 seconds. An enemy can be hit by both slashes, but will only be damaged once. Range: 400. Cost: 10% of current HP. Cooldown: 8/7/6/5/4.

-(W) Pain supression: Passive: Zhen Fo gains 0.1/0.2/0.3/0.4/0.5% additional lifesteal for each Pain he has. Active: Zhen Fo gains a shield that absorbs 60/100/140/180/220 (+ 50% AP) damage for 3 seconds. The shield absorbs 0.8% more damage for each Pain he had the moment he activated this skill. Cost: No cost. Cooldown: 12/11/10/9/8

-(E) Blood-soaked blade: Zhen Fo's next basic attack deals 20/40/60/80/100(+8% AD) plus 8% of target's missing HP(max 50/75/100/125/150 against creeps) as bonus Physical damage and slows the target by 10/15/20/25/30% for 2.5 seconds. The cooldown of this skill is reduced by 0.5% for each Pain Zhen Fo had the moment he landed the strike. Cost: 5% of current HP. Cooldown: 5 seconds after landing the attack.

-(R) Mutual Pain: Zhen Fo lunges a moderate distance towards the target enemy champion, thrusting his sword on himself and the target champion, suppresing both for a brief period of time while the animation completes (0.2 seconds, this effect can't be cleansed or canceled nor is it affected by tenacity. Interrupts channeled abilities) and dealing 50% of the target's current HP as physical damage. This skill ignores 10/20/30% of the target's armor. After using this skill, Zhen Fo gains 0.2/0.35/0.5% damage reduction for each Pain he has during 10 seconds. (Note: the damage reduction is not static, and varies for the duration as Zhen Fo gains or loses Pain.). Range: 600. Cost: 30% of current HP. Cooldown: 100/90/80
