Possible idea for Aatrox rework

So ive been thinking what kind of abilities would make aatrox similar to how he is in the lore and so i started creating this.

!Please dont be too critical this is my first post and im not sure if his kit is balanced or not.

Passive

• the darkin side - everytime aatrox basic attacks or uses an ability he gains stacks of GLORY OF WAR.When he reaches 100 stacks the darkin inside him wakes up damaging nearby enemies and granting aatrox bonus auto-attack range , attack damage and attack speed for 10 seconds.(stacks decay over time)
• war never ends - the first time aatrox health drops below 10% his health is restored to 25% and gains War is Eternal.During War is Eternal he gains 100% lifesteal but his health cannot go over 25%.

(The Darkin Side dmg is max health dmg,War Is Eternal lasts for 5 seconds,War Never Ends has a 300 sec cooldown, Abilities grant 10 stacks each while basic attacks on minions grant 5)

Q - Darkin Flight

Aatrox smashes into the ground dealig phisical dmg and knocking up enemies in the center.

While the darkin is awaken this ability does 3x more dmg to enemies in the center while slowing enemies outside its center.

(Empowered q cannot be interrupted and doesnt give GLORY OF WAR stacks)

W - Blade of Torment

Every time aatrox takes dmg the sword stores the blood.When he activates this ability Aatrox's next auto-attack gains 100 range and deals bonus dmg based on the ammount of blood the blade stored.

While The darkin is awaken the auto-attack gains 100% life steal.

(This ability consumes all blood on use, and has a minimum dmg)

E - War's Reach

Aatrox points his blade forward,the blade then extends dealing phisical dmg to all enemies it hits.If the blade connects to an enemy champion while extending it briefly slows them and steals a percentage of his health.

/* While casting this ability aatrox is rooted in place,also i think it should have a loong cast time */

R - Wrath of War

While War is Eternal is active aatrox can activate Wrath of War to become rooted in place and invulnerable for 2 seconds . During this time tentacles of blood lash out from aatrox towards nearby enemies slowing them briefly and stealing health.

/* While making this ability i had in mind Mercer from the game Prototype and how he had tentacles lash out of his body to dmg enemies.Also Aatrox's splash art depicts his blade stealing blood from bodies in the form of strange blood tentacles */
