I'm gonna go through abilities and point out some things.
Disclaimer - Since there is no hint to his base stats and gun's function, I'd assume he is a bruiser hero who relies on lifesteal, like Victor.
1 - How long is the base distance? How long is the max stun duration? Self-stunning can be risky, especially if you lunge forward and outposition yourself. Also, 15% base lifesteal is too small for a single-target ability.
2 - Does it automatically trigger upon dashing? I think making this into a self-buff ability instead of a proc per dash ability, since you can boost dashes with 3.
3 - Flight is pretty out of his bruiser archetype in my opinion. You might want to give bonus Spirit damage per shot to his gun(Like Vindicta) if he is going to be used as a gunner. Boosting dash instead of locking your position for a short time is also a great design, but restricting the dash direction to your aim can be cumbersome in some situations.
4 - Does he also die when all the mosquito spawns die? He could rather spawn mosquito swarms(Like Death Prophet's from Dota 2 Ultimate) instead of transforming into one, so he can benefit from other buffs as well.
That is all.
He's an area denial lifestealer, with abilities that extend his "Influence" and helps keep him alive. Agile and annoying.
His gun, "Blood Fee", is a 16 shot, semi-fast revolver that has fast-moving projectiles that does great at medium range, and has some potential longer ranged.
1 - I'd say he'd go about 11 meters at a speed of 5.6m/s and can subtly change his direction. The stun lasts as long as Blutson impales you. The distance can be extended with Duration Extender, while the size of the impale can be extended with Expansion, allowing for easier impales.
2 - Yes. The trail triggers when you dash, and trails as long as the dash, with the actual duration of the trail being independent of the amount trailed.
3 - Flight is basically meant to play into thirst and trail, and the increased firerate makes it so that self-defense is more viable, as well as playing as a literal mosquito, and can be even more menacing with good upgrades. And how it can play into his other abilities, his reduced stamina on dash makes trails of pests constant, and the thirst can be used while flying and doesn't cancel flight.
4 - He does die when all mosquitos are killed (Because he literally is the mosquitos), and all of the health that the mosquitos have will be transferred to Blutson when he returns to form. I wanted it so that his swarm is unique compared to other ults, and didn't want it to be just another Seven, Haze, or Mina ult, while also making it some kind of "Plague of Mosquitos". And before you ask, yes, the items that you buy also apply to the mosquitos. (Stuff life Spirit Lifesteal/Infuser increases their lifesteal)
