What I did
So I change all of his skill. Stats: Increase range to 475.
- Passive: So I nerf him with his passive. You can't reduce the damage imediately from junglers anymore. Howver, fully stacks will almost negate the targets damage.
- Now, it deals more damage with the stack from his passive.
- Change the ability to lock on: Instead of E, he will need to land his basic attack. **This will reduce his early game trade due to his small attack range.
- Nerfing his passive so I add a new passive to W. Increase his Ar and MR. This will help him to fill the stacks on the target.
- No more slow. Instead, he can heal himself.
- Adding 300 bonus range not only open him opportunity to trade but also reduce the nerf from his Q.
- If the target stand in the middle of creeps, he gets more damage as now there are maximum of 3 targets. Move the slow from Q to E. And no more ar reduction.
- Watchout when using this when escaping. If the target can be invisible, you have high risk to slow yourself.
- The sub skill is for high mobility gankers. As he flash to you, the slow and the damage will threaten him from getting to near. And it works well with your ultimate.
- Move the ar and mr reduction to R. This will help you to kill the target better.
Conclusion: There are nerfs and buffs but overall buff him. He is now a very tanky mage, though, he still needs to basic attack. This kit still share the same strategy from the old one while making new one. He should begins with E for better farming. At level 2, level up Q for more damage. At level 3, the jungler can gank now, level up W to reduce the damage. Level up R whenever you can. When harrass, use your E, then your Q. Shouldn't use E when you can lose enemy sight and there are no target around. When ganking the enemy laner, activate your E, use your R and wait for the E to burst. You can still pair him with a support. Pair him with support that can CC the enimies like Leona, Braum, 20px Blitz will help him trading while a high burst of movement speed from Karma also works well.
