Tho'rax, Lord of the void (Champion idea)

Tho'rax Lord of the Void Health - 660 - 1790 Health regen. - 6.65 - 15.90 Mana - 466 - 1586 Mana regen. - 7.1 - 17.26 Melee - 175 Attack damage - 58 - 116 Attack speed - 0.67 (+0% - 65%) Armor - 24 - 76 Magic resist. - 26 Move Speed - 340

Passive - Hunger for Power: Every time Tho'rax kills an enemy, he gets additional 2-20 (based on level) AP. If he gets an assist, he instead gets 1-10 AP. Additionally, if he dies, he loses half of his current bonus (minimum 1 bonus overall AP) (for the passive, you would have 2 buffs on your buff bar from the beginning, one being bonus ap for kills, and one for assists)

Q - Power of the Void - Cooldown – 12/11/10/9/8 seconds – Mana Cost – 40/45/50/55/60 Passive - Your normal auto attacks do 20% of your AP as magic damage.
Active - This empowers your next auto attack to do 60/80/100/130/150 + (80% AP) as magic damage. Whilst this ability is on cooldown, you lose the passive and deal 10% reduced damage.

W - Into the Void - Cooldown - 20/18/16/14/12 - Mana Cost - 70/80/90/100/110 Tho'rax goes through any terrain and appears on the other side (like bards magical journey, but nearly instant and only for you).

E - Explosive Void - Cooldown - 7 seconds at all ranks – mana cost – 100 at all ranks Places a bomb on the enemy champion of your choice and it will explode after 5 seconds or that champion dies. The blast does damage equal to 70/80/90/100/120 + (90% AP) in a range of 300 around the target. This bomb can be transferred to a different champion by that champion clicking on the champion with the bomb. If the bomb is transferred to another champion, then 10% of the bombs damage is turned into true damage. If the bomb kills the target or the target dies whilst the bomb is on them, then the cooldown goes to zero and the mana is refunded. (_ for example, a tank malphite could transfer the bomb from the adc with 100 health and take the damage for him, but when he transfers it, 10% of the damage is true damage_)

R – Void Annihilation – Cooldown – 120/100/80 – Mana Cost – 160/180/200 Passive – You gain 10%/20%/30% bonus movement speed Active – Summons a hand from the void under the enemy championof your choice(point and click). This hand takes the champion and pulls them under the void for 0.5/1/1.5 seconds. When they emerge they take 150/300/450 (+ 70% AP) magic damage. Dakthar heals for 10% of the overall damage dealt.

(I would have a lore for him but i am bad at coming up with things like that, same with the art, i dont have a picture of him cause i cant draw. Also, i dont really know what kind of quotes he woud have, but if i were to have some, there would probably be something about kogmaws quote "Terror Coming... Daddy Coming!", i was thinking this is the "Daddy" that he is refering too.) Feel free to comment any ideas you have on the champion, and if you want to you can come up with lore ideas and quotes and so on.

Also if you dont like the design or think there is something wrong with it, please comment letting me know what it is, so i can try to fix it.
