[Champion Concept] Kudlak- The Night Prowler

Attack Range- Melee

Passive: Demonic Sense- When a nearby champion goes below 50% hp, Kudlak transforms temporarily gaining large boosts to movement speed and attack speed, and has true vision in a radius around him for the duration. This effect can only happen every minute or so.

Q: Intoxicating Fangs- Kudlak quickly bites a nearby champion/minion, dealing bonus physical damage at first, with minor lingering physical damage for a long duration. Intoxicating Fangs dot (Devouring Venom) will spread to nearby enemies who linger close enough for too long, and can refresh+stack itself up to a cap. Somewhat short cd. Say around 8 seconds.

Higher levels increase rate of infection, initial damage, and reduce cooldown.

W: Flight of Terror- Kudlak uses his wings to glide forward a moderate distance at fast speeds, becoming intangible for the duration and dealing physical damage to enemies he passes through. At any point in flight he can reuse the ability to instantly stop at his current location. Pretty long CD, say 15-20 seconds.

Higher levels increase damage, reduce cooldown, and increase max flight range.

E: Feast or Famine- (Toggle) While off, autoattacks and abilities gain increased damage (think of Vladmir's ult, but smaller and only for Kudlak) on targets inflicted with DV based on stacks, while toggled on it will consume all stacks of DV on targets he autoattacks, healing him based on stacks consumed (5 stacks consumed at most per auto).

Higher levels increase bonus damage and healing.

R: Insanity's Horizon- Upon use, inflicts all nearby enemies with a certain number of devouring venom stacks, while greatly increasing the rate of infection and increasing the cap for a short duration. After the duration ends or if the new cap is reached, all stacks above the normal cap explode, dealing damage based on the number of stacks above the cap+base damage, as well as stunning them for a short duration. Those who don't reach the base cap due to potential Feasts consuming it, are stunned for half the duration and only take the base damage. Moderate cooldown, say 100-120 seconds.

Higher levels increase stack cap, rate of infection, and decrease cooldown.

Basically a sort of initiator/sustained melee AD...

As far as looks go, I ain't much of an artist but I'd figure he'd be grayish-skinned, kinda slouched over, a little insane looking, white hair, bright yellow eyes, long+sharp claws, a mess of fangs/teeth where a mouth would normally be, and also have pretty demonic looking wings...

This is what I have so far, some input would be nice.
