Champion Concept: Void-based Marksman (The Daughter of the Void)

To be honest it's more of a set of possible abilities so far, without even damage ranges and mana costs (since it's obviously a nigh impossible thing to balance to anyone) + champion's identity and so on...

Overview: [The Daughter of the Void] is a ranged AD marksman with lobbing AA-animation who uses the Void-charged goo and sludge against her enemies, relying on passive proc-system of 4!-hit pattern and slowly wearing down her opponents if they make mistakes in positioning themselves, while eluding their own retaliation and gank attempts.

Lore: (This part is WIP but as a base I wanted to use the partly forgotten "Riot Lore Journals" and make this champion The Daughter of Kassadin, who was sent to the Void by Malzahar, obviously, she was brought back as an Avatar of the Void energies)

Abilities:

[Passive] Every concecutive auto-attack on single target [The Daughter of the Void] lobes scalingly bigger globes of sludge, which deal bonus magic dmg equal to 7,5 - 10 - 12,5% (second, third and fourth globe) of total AD. On the fourth consecutive hit the target is snared for 1/1,25/1,5 second and passive goes on 10 second cooldown if the target is enemy champion. Stack-status holds up to 5 seconds.

[Q] Void Globe RANGE: 750 / 250 COOLDOWN: 9 seconds [The Daughter of the Void] lobes an extra large globe of sludge at the target location, dealing physical and magic damage upon impact to all nearby enemies and slowing them by 25% for 1 second. Enemies close to the center of the globe's impact are slowed for 50% for 1,5 seconds. Also it adds 1 stack of the passive

[W] Miasma cloud RANGE: 350 COOLDOWN: 35/33/31/29/27 seconds Surrounds [The Daughter of the Void] with a cloud of void miasma for 4 - 5 - 6 seconds. (4 seconds - 1st, 2nd level, 5 seconds - 3rd, 4th level, 6 seconds - 5th level) The cloud obscures enemy vision AND ally vision, reducing their Sight radius and causing the enemy AND ally (with the exception of [The Daughter of the Void]) to miss all their auto-attacks if they remain in the cloud. As [The Daughter of the Void] escapes the cloud, she (only she) gains a 35%-40%-45%-50% MS boost and ignores unit collision for 2 seconds.

[E] Goo Pool RANGE: 500 / 125 COOLDOWN: Storage time - 35 second, Cooldown on setting one pool - 2 seconds [The Daughter of the Void] sets a pool of goo at the target location. Enemy champions and minions who come into the area of goo pool take periodic magical damage while standing inside the AoE of the pool and gain one stack of passive each second, allowing [The Daughter of the Void] to start proccing her passive from the amount of stacks generated.

[The Daughter of the Void] can set up to 3 pools, with each one lasting up to 1 minute. Pools are visible to both allies and enemies. The oldest pool of goo deactivates itself if new one placed breaks the limit of 3. Once pool is triggered by the Enemy Champion for the first time - it's life time is shortened to 5 seconds.

[R] Void Whirlpool RANGE: 650 / 600 (350 - outer ring / 250 - inner ring) COOLDOWN: 110 / 90 / 70

[The Daughter of the Void] creates channeled huge whirlpool led with Void-charged goo and sludge leading straight to the Void. It lasts for 2,5 seconds before it triggers the second stage of CC and Damage Part of the Ultimate ability.

There's two stages of CC inflicted:

First stage: The farther enemy champion is, the more his movement speed is lowered, in turn, lowering the chances of escaping. (from 33% to 77% of movement speed)

Seconds stage: Champions standing on the outer ring of the Whirlpool are stunned for 1,25 seconds. Champions standing in the middle of the Whirlpool are snared for 3 seconds. Also, only the inner ring receives the damage of this ability.

I'm seriosly interested in community feedback and will patiently wait for it.... ^^
