Hi, my name is "RNX EpicFailGuy" and I`ve been playing league of legends since early season 4. I`m currently Silver I and climbing. I`ve played Jinx for a very long time now, she is one of my favorite champions in the game with her insane late game damage and her range in the laning phase with Fishbones. I also love how she can kite champions INSANELY well because of her very short basic attack animation.

Pros-
Great wave clear and poke damage
Ult causes tons of damage if well aimed
Really good passive to escape team fights
Insane damage to tanky champions in the late

Cons-
No escape abilities
Short range with Pow-Pow, the Minigun
Weak to CC
Very bad attack speed in the early

Passive - Get Excited!

Jinx gains 175% bonus movement speed which decays over 6 seconds whenever an enemy champion or structure dies within 3 seconds of being damaged by her. Additionally, she gains 15% total attack speed for the same duration, stacking indefinitely. - This passive is very useful in the late and in the laning phase. One of the uses in the laning phase is when you and your support is taking a tower bot, if the enemy AD carry is alone but still near the tower, when you kill the tower you can use your passive to catch up to the enemy AD carry and either slow them with you Zap! of snare them with your Flame Chompers!

Q - Switcheroo! RANGE: 150 COST: 20 MANA PER ATTACK STATIC COOLDOWN: 0.9

TOGGLE ― Pow-Pow, the Minigun FULLY STACKED BONUS ATTACK SPEED: 30 / 40 / 50 / 60 / 70%
Jinx's basic attacks each grant her bonus attack speed for 2.5 seconds, stacking up to 3 times for a maximum of「 0% - 70% 」bonus attack speed based on level rank

TOGGLE ― Fishbones, the Rocket Launcher BONUS RANGE: 75 / 100 / 125 / 150 / 175
Jinx loses 15% total attack speed and her basic attacks gain bonus range. Additionally, each basic attack consumes mana and deals 10% AD bonus damage, dealing their damage to all enemies around the main target. The bonus and splash damage are both factored into Critical strike icon critical strikes. - Always try to use Pow-Pow, the Minigun when in a 1vs1 because it does better singe focus damage but when fighting in a team fight use Fishbones, the Rocket Launcher for the AoE damage and range, remember when you get an assist or kill your passive pops so you can go deeper in or run away.

W - Zap! RANGE: 1500 COST: 50 / 60 / 70 / 80 / 90 MANA COOLDOWN: 10 / 9 / 8 / 7 / 6
PHYSICAL DAMAGE: 10 / 60 / 110 / 160 / 210 (+ 140% AD) SLOW: 30 / 40 / 50 / 60 / 70%

ACTIVE: After a short delay, Jinx fires a shock blast that deals physical damage to the first enemy it hits, Sight icon revealing and Slow icon slowing them for 2 seconds. - Use this ability when chasing someone or just for the damage, it`s a very easy ability to juke which is it`s main weakness but when you learn to use it more and more you`ll be able to predict enemy movements and easily land it.

E - Flame Chompers! RANGE: 900 / 50 COST: 50 MANA COOLDOWN: 24 / 22 / 20 / 18 / 16
MAGIC DAMAGE: 80 / 135 / 190 / 245 / 300 (+ 100% AP)

ACTIVE: Jinx tosses out 3 chompers that, after a 0.7-seconds arming time, explode on contact with enemy champions, dealing magic damage over 1.5 seconds to all enemies within a small area, Root icon rooting the champion who set off the chomper for the same duration. - Use this ability against enemies in a fire-fight and place it either behind them if you know you`re going to be able to kill them, or on them if you don`t know. If you place it behind them it`ll stop them from being able to run away and if you place it on them it`l force them to move away, meaning the`ll lose some basic attacks.

R - Super Mega Death Rocket! RANGE: Global / 225 COST: 100 MANA COOLDOWN: 90 / 75 / 60
MINIMUM PHYSICAL DAMAGE: 25 / 35 / 45 (+ 10% bonus AD) (+ 25 / 30 / 35% of target's missing health)

ACTIVE: Jinx fires a Super Mega Death Rocket! Minimap rocket that travels in a line, exploding in an area upon hitting an enemy champion. Enemies caught in the explosion take 10 - 100% of the rocket's physical damage, based on the distance the rocket traveled, plus additional physical damage based on their missing health - 420 blaze it incoming. My favorite ability, it does insane damage on hit and it`s AoE! The problem is, is that its very easy to juke if the enemies have good enough reactions. If they have any dashes (for example Lucian`s Relentless Pursuit or Graves` Quickdraw) try predict them using it. Aim your ult slightly to the right or left and then you can /All chat and laugh at them.

Great item on Jinx as it gives her a lot of AD in the early and also it makes her crits do 250% damage instead of just 200%. This is INSANE especially in the late where she relies on her crits so much
This is probably my favorite item in the game on champions like Jinx. Phantom Dancer has definitely become under-rated in this preseason but in my opinion it is still the best item on Jinx. You have no idea how much I love it, it gives absolutely every factor Jinx needs. An insane 45% attack speed and a whole 30% crit chance. Also its very helpful against 1vs1s as the passive states that the last enemy champion hit deals 12% less damage to you.
Again, great item. The sustain is very nice as sometimes in team fights you need to be kiting against most tanks that are focusing you. Giving you the extra sustain in these fights is definitely the difference between losing and winning a game
Rapid Fire CannonI`m not 100% sure about this item but I definitely think that it`s useful to Jinx to some extent. the 30% crit chance and 30% attack speed is very nice and the fact that your first basic attack when charged will do extra damage DELETES champions
Lord Dominik`s RegardsThis is the basic armor shredding item that all AD carries should build. Very nice as Jinx is a late game champ and you`ll mostly be fighting heavy tanks in the late
This is a nice item when fighting champions with a lot of built in heal effect (for example Nasus` Soul Eater and Nunu`s Consume) Also this works against Soraka`s Astral Infusion. Furthermore it also works if the enemies have life steal items for example Bloodthirster and Death`s Dance

My runes for Jinx and pretty much all AD champions is this. Everything about it is normal maybe apart from the Greater Glyph of Attack Speed. Personally I love these glyphs because you don`t need much MR in lane as the main damage dealer is the AD carry. The extra attack speed definitely gives you an advantage over your laning opponent.

Another rune page I would recommend is going for flat Greater Glyph of Scaling Magic Resist. This rune page is for fighting a support which isn`t building AP and the enemies don`t have much AP champions.

In conclusion Jinx is a very strong hyper-carry champion, with insane burst in the late and great AoE damage that destroys squishy champions. She is definitely one of the funnest champion in league to play, and the one that gets you most kills :) I hope you guys enjoyed my guide and if you did I would really appreciate an up vote and also leave a comment, if you either liked it or didn`t :) Good like in the fields summoner ^_^
