[Champion Concept] Omnistar, Reaper of the Freljord

This will be a purely written-based description of a champion concept, from lore to potential in-game abilities and a few interactions with other champions. I am not that great with descriptions, but I'm worse with trying to draw. _;

Basically: Burst Assassin Caster.

Description: Height: 6'11" Weight: 160 lbs. Body build: Slim Hair color: Black with an outline of a blue edge. Eye color: Icy blue. Skin color: White/Caucasian. Clothing: White coat, pants, and heavy-set boots built for durability and protection from the cold. (Release skin concept: Infernal Omnistar giving him a black coat and pants, with fire effects coming from his weapon.) Weapon: A 5'7" Scythe. (Width of blade 13") Black metal with a white tip.

In-game abilities: These are only descriptions of them, as numbers are well-subject to change later on.

Passive: Reaper Omnistar's basic attacks attack in a cone-shape in front of him. Melee with 300-425 range.

Omnistar attacks in a pattern, swinging right-to-left, left-to-right, and on his third consecutive autoattack on one target, he slams his scythe down upon them, dealing bonus damage.

Omnistar's abilities do not use mana, but instead drain from his health.

Q: Reaper's Flight Passive: Gives Omnistar armor penetration. (Percent based, scales with ability points.) Active: Omnistar drags his scythe through the ground forward, slashing upwards and knocking all units hit in the air, dealing physical damage.

W: Soul Harvest Passive: Omnistar gains % spellvamp and lifesteal Active: Omnistar places an ancient Freljord symbol on the ground in a target area. After 1 second, it erupts, dealing magic damage and slowing all inside.

E: Feint Active: Omnistar blinks behind the lowest-health enemy in range. (Prioritizes champions.)

R: Reap Active: Omnistar selects a target, becoming untargetable for .5 seconds and appearing at his max attack range behind them, auto-attacking them as he becomes targetable again. Activating this ability causes all of his other cooldowns to become instantly refreshed. You may reactivate this ability within 5 seconds on the same target, however the second activation does not refresh cooldowns.

Yes, it's basic. But I mainly just want to see a champion in league that has a scythe that actually USES it. (I.E. Fiddles and Karthus both being ranged mages. >.>) Feel free to leave feedback/suggestions/telling me I misspelled things/so on so forth. /))
