[CHAMPION CONCEPT] Chronus, the Darkin Wall (tank/support)

I'm starting to think I have an addiction in creating champions XD I don't have the digital art skills, and I barely have the sketch skills, but I'm always open to critiques. I have three other ideas, essentially a mid laner, jungler, and adc darkin. If this gets any traction, I'll see if I should post some more Darkin champ ideas.

Health: 603.35 (+89.5 per level) Attack Damage: 58 (+2.9 per level) Attack Speed: .622 (+2.6% per level) Movement Speed: 335 Health Regen: 8.24 (+.6 per level) Armor: 28 (+3 per level) Magic Resist: 32.1 (+1.25 per level)

Passive - Blood Bond Chronus' blood bonds with a chosen ally. If chosen ally is below 50% health and Chronus is below 45%, while near each other, health is balanced out, 1.3 health per second, sustaining both parties.

Q - Transfusion Chronus forces the blood around him to move between enemy and ally champions. 10% of his health can be moved to an ally or 8% of an enemy’s can be stolen and moved to himself or to and ally. COST: no cost - 5% current health
COOLDOWN: 22/20/18/16/14 seconds RANGE: 500

W - Rag Doll Chronus grabs a nearby enemy and tosses them in a chosen direction. Dealing damage and slowing the enemy by 25% for 1/1.5/2/2.5/3 seconds. COST: 10% current health COOLDOWN: 16/15/14/13/12 seconds RANGE OF TOSS: 175

E - Surrounding Vessels Chronus rolls in a chosen direction, creating a shield of blood for him and a nearby ally for 2.25 seconds. Any remaining shield explodes, stunning the enemy for .75 seconds. COST: 15% current health COOLDOWN: 21/19.5/18/16.5/15 seconds RANGE: 575

R - Blood Grounds Chronus slams the ground channeling his blood in the surrounding area. Enemy champions caught in the area are slowed by 30%. After 2 seconds, a wall forms around the edge, trapping all inside. Allies get a shield made up of 15% maximum health. Chronus forcibly turns it 100/140/180 degrees to either side, dealing damage with the turn to all champions, and bonus damage if targets collide with terrain.
COST: 20% current health
COOLDOWN: 150/130/110 RANGE: 500/525/550

I haven't figured out the damage yet. I know Chronus should probably look more humanoid, but until Riot releases the next Darkin, shapes and sizes could possibly vary, adding the potential for more diverse characters. If anyone's got some lore to add, feel free to post it :) Have a good one.

Potential Dialogue "Oh, we are going to have a fun time together." "I follow Aatrox." "Another day, another body." "You can only run so far." "And I'd do it all again in a heart skip." "My shield and I are one. And my shield is two...wait what?"
