New Champion Idea: Asor, The Arcane Vigilante
Asor, The Arcane Vigilante: (Ghost/Devil Type of Creature)
Asor uses mana for his moves.
Passive: Mark of Arcane
Every 6 auto-attacks, Asor's next attack (Whether it is his Q, E, R, or Auto-Attack) will have a lasting effect of magic damage. It deals (+6) magic damage every 0.5 seconds for 3.5 seconds.
Q: Arcane Mastery
Asor blasts a purple ball (like ahri's Q).
The ball has no effect (like a stun or slow) on the target it hits. (The move is like Xerath's E, just has no stun, it just does damage)
Range: 850 range Mana: 50/60/70 mana Cool Down: 3/4/5
W: Magic Extraction
Asor begins to absorb +1 mana and +1 health every 0.5 seconds. If any magic damage or physical damage is used within any area in the map that can be seen, he gains +3 mana and +3 health every 0.8 seconds
(This move is like Master Yi's meditation. Asor cannot move while using this move, but if he does he disrupts his absorption of mana.) This move will continue if the player does not move Asor for 7 seconds.
Range: Anywhere on map as long as it can be seen by Asor. (Such as placed wards, or turrets that are still standing) Mana: 80/90/100 mana Cool Down: 20/25
E: Enhanced Technique
Asor gains 45% attack speed, and all of his moves deal (+20) magic damage. This move stays with Asor for 10 seconds. If Asor kills a unit with his Q he gains +2 ap damage. (Like Veigar's Q), but if Asor's E is not on, and Asor kills a unit with his Q, there will be no stacks.
Range: Self Mana: No Cost Cool Down: 9/10/11
R: Calling of Obliteration
Asor summons arcane magic at his target. Little purple lights begin entering the body of the targeted champion. The move is like Asor's W: If Asor moves, the move will stop, except this time, the move does less damage if he stops while it charges, but if he waits the 4 seconds, the move will do its maximum damage. If he stops any time sooner, the move won't do as much damage as it actually could.
When Asor targets the champion, and starts using his move on them, they cannot escape it. The damage will be done even if they are out of sight.
Range: 775 Mana: 100 mana Cool Down: 140/150/160

Now where he is from:
Ionia
Lore:
Asor, was one of the first to discover and harness the power of Arcane Magic. When he used it along with his pupils and masters, they were unmatched in all of Ionia. They were defending the city with ease, and for a great deal of time, Ionia was secure and at peace. One day, Asor entered a cave. He felt a great power within him, but soon, it overwhelmed him. He was consumed by the darkness, yet still feeling the arcane within him, his power increased greatly.
The masters felt a dark presence within him, when he returned. Asor looked at all of the Arcane Mages in disgust. He knew he had greater power than them, and the masters understood that as well. Asor, knowing well that the masters were vulnerable against him, decided to eliminate them.
After killing all of the first Arcane Mages, Asor was weak and needed to recover before taking Ionia for his own. His injuries cost him years of healing, and Ionia itself. Ionia had evolved in the many years he had left. He knew there were many knew people who could defend Ionia from him. He knew he had to become even stronger.
He fled to the area he first learned Arcane Magic, hoping that he could learn something else there. He found a tree using Arcane Magic. At first he felt happy. He had found another Arcane Magician, but then the feeling of darkness closed around him. He quickly attacked the tree. They began fighting, showing off their Arcane Abilities. The battle caused both of them to flee. Asor experienced another few years of healing.
Asor then was confronted by two figures. They led him to a place where they said he could learn everything he could about Arcane Magic. He was led to the League of Legends. Asor was thrilled to know there was a place where he could learn more about the magic he studied and used ever since it had first been discovered.
Asor never forgot about his heritage, and the day he destroyed them all, to rule over Arcane Sorcery.
