The Odd One

Inspired by this; http://boards.na.leagueoflegends.com/en/c/gameplay-balance/2T5BEw8q-we-need-a-champion-who-is-really-resistant-to-magic-since-they-dont-believe-it-exists

This champion is a manaless mid-ranged fighter. He/she is a crazy hobo from the outskirts of Zaun, wearing a mask, carrying hatchets (for mid-range auto attacks) and a chainsaw.

Passive: Mask of Insanity - Magic damage is reduced by XX% (+ .XX MR Ratio) and stored in the Insanity meter. Insanity capacity increases with levels and with MR, slowly reduces over time, faster out of combat, and slightly faster still while in the brush.

If Insanity reaches 100%, all of the stored damage is dealt to you, and you're marked with Shattered Delusions for 10 seconds, or until you pick up your mask (knocked off and away from you).

Q: Rev Up - You grab your chain saw and rev it up, switching to Melee range for XX seconds or for 5 attacks. Each auto-attack deals extra damage and has a small AOE in front of you.

Rev Up has a secondary cast on a short cool-down to briefly Fear nearby enemies. You can move while revving the chainsaw.

This ability is disabled while marked with Shattered Delusions.

W: Stalking / Flee - You move faster towards enemy champions or brush. While in the brush, you gain XX% further vision. While marked with Shattered Delusions, you run faster away from enemy champions instead, and lose the vision bonus.

E: Terrorize / Terrified - You leap a short distance towards the target enemy champion, interrupting channeled spells. Leap range is increased from Brush. While marked with Shattered Delusions, you leap away from the target enemy champion instead, and lose the range bonus.

R: The Special Sauce - Throw a molotov to the target area, dealing XXX damage over X seconds, burning down brush for 60 seconds, and destroying traps. You hold three charges at once, and have to go back to base to mix more.

If you die, you can throw the rest of your molotovs on a short cooldown for 10 seconds afterwards.
