New Idea for Mage Champ Skillset!

First Champ design idea pls be gentle

Passive: The champion revolves around a resource called "Night Orbs" which can be used in a variety of ways. He conjures one every four seconds, and can have up to twenty. However, if he gets hit by an enemy ability, a Night Orb will be lost.

Q: Skillshot ability that throws a Night Orb at a target enemy. If an enemy champion is killed with this ability, the next W used in addition to it's normal effects will heal for 20% of the enemy champion's max health steal 15% of their ability power.

This ability is meant to be his main damage tool, like Liss and Annie's Q.

W: Consumes a Night Orb, granting bonus ability power and MS. The effects of this can stack up to three times. The ability comes with the passive effect of permanently increasing his Ability Power by 30 every time he consumes 50 Orbs.

This is his bread and butter. Since he will most likely have low base stats, he must constantly be eating Night Orbs early game to have the power necessary in late game, decide if he needs to throw an orb to damage the enemy or throw a ring in the next skill, plus have the ability to avoid skillshots so he has the ability to even use the Orbs, since he loses one each time he gets hit by an enemy ability.

E: Uses up four Night Orbs to use as a bomb against the enemy. This ability is a skillshot like Lux's E and Gragas's Q that travels to a certain area and can either detonate when the user pleases or after a period of time. Since this spell is his main source of CC, the explosion of the bomb causes enemies to become stunned for 1 second.

R: Enters a stasis and summons 4 night orbs as pets to attack the enemy, gradually healing HP each second in stasis. The stasis ends after 3 seconds or if all the night orbs were destroyed. The night orbs AI is similar to melee minions or Malzahar Voidlings.

Some changes I'm thinking of Adding:

-Additional Passive where he gains 5 Night Orbs if he falls below 20% HP which can only occur every 90 seconds. -Ult lasts 4 seconds -Q slows for a small amount -Use of HP as an additional resource -Mana -Night Orb Cap increases with rank -Q is point and click -E is an AoE Fear -E is a knockup -Give W passive greater effect -Make W passive proc every 100 Orbs

What do you guys think?
