Jared, the Lucky Bastard

Passive: Lucky Bastard

• After successfully dealing the killing blow to a unit, Jared will either permanently gain 4hp, 3mana, .5 ad, or .5 ap. Killing a large monster, siege minion, or champion will make this passive trigger 2 times.

Q: Weak Spot (8 second CD) (60/65/70/75/80 mana cost)

• Jared picks up a rock from the ground and hurls it at an enemy champion, which conveniently hits them in the leg, slowing them by (10/15/20/25/30)% (+5% per 100 AP) for 2 seconds and dealing 20/30/40/50/60 physical damage(+ 110% AD).

W: Close Call (25 second CD) (No cost)

• Jared gets lucky, dodging the next auto attack or ability within 2 seconds.

E: Slippery Skin/Double Up (20/18/16/14/12 second CD) (60/70/80/90/100 mana cost)

• Passive: Jared always seems to slip away from sticky situations. Slows are 10/15/20/25/30% less effective against him.
• Active: Jared loses the passive portion of this ability and doubles his bonuses from his passive for 5 seconds (this will not restore health and mana, but if he has lifesteal, it will allow him to 'overheal' himself you could say).

R: Lucky Throw (140/120/100 second CD) (100/120/140 mana cost)

• Jared takes his tempered wooden staff and throws it at his enemies legs, conveniently tripping them and making them fall, stunning them for (.75/1/1.25) seconds and dealing 100/200/300 physical damage (+140% Bonus AD) (+70% AP), then slows them by (30/40/50%) for (1.5/2/2.5) seconds after the stun. Jared cannot auto attack while his staff is on the ground, he has to pick it up first. If he does not pick it up in 5 seconds, he finds another on the ground(not sure how else for him to get the staff back). This does not stack with Weak Spot's slow.

I am not completely sure on the numbers for the passive. Currently if someone were to get 100 cs at 10 minutes, and got each passive stack 25 times, then you would have gotten bonus 100hp, 75mana, 12.5 AD and AP. Now if someone reached 80cs at 10 minutes and gotten each passive stack 20 times, then they would have gotten bonus 80hp, 60mana, 10 AD and AP. Towards late game if someone were to reach 300 cs and the passive was split evenly they would have gotten bonus 300hp, 225mana, and 37.5 AD and AP. It obviously is not a huge stat boost but can vary based on LUCK.
