Hello, my summoner name is Kiin3z just came up to 1600 elo and playing Tristana as my main.
This guide is about Tristana, i prefer calling her Rihanna.
To revenge on Chris Brown :> .

I got 85% win ratio with her and insta play with Riot Girl skin.

No more **** talking, let's take a trip !

For Masteries i go 24/0/6 .

Fizz patch V1.0.0.129 changed the whole mastery page with new abilities etc.

With the new mastery page I play 24 in offense 0 in defense and 6 in utility

This will also give us

+10% Armor Penetration
+10% Critical Strike Damage
Improved Exhaust/ Ignite, Flash
+3 AD
+6 Armor Penetration
+6% Attack Speed
+4% Critical Strike Chance
+1.5% Increased Damage
+3% Life Steal
+12 Mana per Level (216 at level 18) (flat bonus)
+1.5% Movement Speed

OBS! I TRY TO UPDATE THE STATS AFTER 10 GAMES WITH TRISTANA !SBO

Season 2 I have playd total 35 games with Tristana (76% win)
32 wins and 10 lost , 90% off loss is because of BIG trolls :/
7.5/4.4/6.3 K/D/A per average game, my ranked KD ratio is really low because yeah Tristana shines MID/LATE game, early game she is a farming machine !

Summoner Spells

Okay so let's start with the skill sequence, I see lot of peoples is uncertained about my skill sequence because I'm not using the free ASPD early/mid game.
Well the skill sequence that I have chosen is for a little bit longer lane gaming, feel free to level up how ever you want but, I recommend to skill up after the game situation.

Long laning games I recommend this for 2vs2 because Rocket Jump and Explosive Shot is an hard burst, the enemy will back off for sure if they is getting bursted that means you will get some free auto attacks hopefully a kill.
Second situation
I do always skill up the same, but if the enemy team starts early fight I might skill up the Rapid Fire since there will be enemies that is focusing me, won't be so smart to jump in with Rocket Jump to deal damage then.
And when the early teamfight/dragon fights starts and I have ATLEAST one B. F. Sword then I start skill up the rapid fire.

Now the question WHY is coming up, WHY don't you always skill up the Rapid Fire.

There is moments when people is stacking armor early to counter you, then your magic damage will shine since you have 3 skills that deals magic, I can play Tristana close to other champions because of my magic damage, the magic damage makes her more powerfull than other AD carries (my opinion) that's why I often win my lane.

Let's say skill up the Rapid Fire early is depending on the situation in your game, I hope I explained well about why I'm getting this early/mid game magic damage

Sona - Best support IMO , good damage, got an heal and good auras , AoE stun AWESOME?!

Janna - No heal, but if played right with good shields you should do fine in lane (start with boots 3hppot)

Soraka - Soraka is not the best with Tristana but could work out, amazing heal (gives armor for tower dive n sustainability), MRes aura (For magic damage bot Sona Kog'Maw) and global heal !

Taric - Taric 50/50 if played right with the stun and Shatter could easy dominate lane

Zilean - Have not played Zilean+ Tristana bot lane, but I don't see anything good in that except the poke and global exp

Kayle - Never tried, Kayle got some good damage and heal with movement speed buff, Intervention is good thoo but not the best support

Nidalee - Let's keep Nidalee in top/mid lane..

Core items

Early/Start game
If you lane with an healer go for Doran's Ring and farm !
You will prolly see that enemy carry takes damage of your Explosive Shot when you last hit minions, when they get low just jump into them and pick up a kill.
If you start without an healer get Boots and 3x Health Potion.
Remember FARM, farm makes you win, farm gives you push, farm gives you money, farm gives you experience points it does everything

Mid / Late game

You should be well farmed right now and at 30 minute cap you should have ATLEAST berserker greaves Infinity Edge Phantom Dancer Bloodthirster Last Whisper (Depends on enemy team )
If your ally got caught just keep farming, do NEVER fight 4vs5 even if you think that you have the power to do that. Exhaust could be popped on you and then that one missing person could be helping you !

That is insane ! and with your armor penetration and survive abilities like Rocket Jump you will even shred tanks in secounds and take no damage, so take the advantage of Rapid Fire too !

Tristana is good for backdoor too don't underestimate her because she is small !

Now i hope there will be more Rihanna's out there in the battlefield with Riot Girl skin !
Hopefully she will carry you out of elohell thoo !

Wish you all luck and play clean don't flame on others, don't rage quit, and if it goes bad remember, FAAARM !
