It seems like he works best in pure 1v1, no minion, no other enemy. There's not always this situation but, well, who knows.

His passive shouldn't have that cooldown reduction since he respawn with full health and mana (luckily, not with refreshed basic abilities) which is very lethal in teamfight if he is fed or something. Should take longer duration to revive, though.

Q is very interesting. It can be both wave clear and powerful stun (to one target). Useful in duel, pretty useless in teamfight. Cooldown and mana is way too high and its range is mediocre. Damage is fine.

W has a very confusing mana cost (do you mis-type or something) and its mechanic is pretty hard to pull off fine. You have to channel for about 2 seconds in maximum level and you can do nothing during that duration? Damage is very lethal against '1' target but, like his Q, do little to nothing in teamfight (but the slow is extremely strong to be honest, but since it is very unreliable, I will say nothing about it)

E is very interesting. Let's say if you have 2000 mana (with Archangle since it synergize very well with this ability) You can trade about 1500 mana and left 500 to cast other ability. With only 1 level, you will have 1500 AP! For 10 seconds! Fix this ability please!

R is fine, I think. Very hard to pull off in teamfight. Cast? Move away and continue the fight. When he complete the channeling everyone will be about across the map and you cannot damage anyone.

His kit is very hard to show its full potential in game. Rework it a bit and I will come to look later.

Good luck :D
