the title says it all

This build is pretty simple with only a couple of things in mind.
The first thing in mind is that Tristana is slow, Right?
so i cure that with adding some phantom dancer's in there her attack is fairly good but i don't like it so i add a bit of infinity edge in there, doing the B.F. sword before the Pickaxe is important because your attack will go up higher and faster.
The skill sequence is in the order in which you will probably use it and it will give you the best results. of course this build is not perfect since I'm only a N00b feel free to say I'm a POS.

Simple enough... Speed is all you need and maybe some damage and other stuff.

Masteries don't do much in this build... you'll still probably own in the end anyway...

Like I said in the intro You'll need these powers first to farm and to snipe and stuff.
the exploding shot is used for farming though you really never use the ability itself it's perfect in getting a lot of gold and maybe damaging the enemy champion itself.
Rocket jump is used for FINISHING KILLS!!!! as it will probably kill you if you used flash recently and you didn't kill the opponent with rocket jump (or assist). Buster shot is useful as the tip says in Tristina's profile, but you should have a person standing behind you ready to catch the enemy champion into his Rape in a bottle.
Remember if you don't win anything with this build, you can always complain, create your own, or try again and ACTUALLY MASTER TRISTINA and not let a loser like me do it for you.

This Character NEEDS teamwork, you can't possibly win a match solo... unless you're really really good. the reason for this is buster shot will not kill enemies at HALF HEALTH you need someone to help you clean up the mess or for you to have a perfect combo. <-- i have those...
anyway in the end you might end up with 2x assists then kills, or you might get kills = to your assists, but teamwork is really a thing Tristina needs, i mean she grew up in the military she knows that.

+THIS IS A RANGED PLAYER DON'T GO CLOSE UNLESS YOU CAN'T HELP IT!!!!
+great for sniping when a minion is fully committed to a battle
+ I love to use this character with TEAMWORK!!!! You can also get kills early in the game if you use this build perfectly (around level 4-6)
- very easy to kill and you have to keep going back and MAKING yourself to go back otherwise YOU WILL PROBABLY DIE!!!
- very difficult to play with in the beginning because you keep wanting to get in close... DON'T GET IN CLOSE!!!! (unless you have to)
+ this person is the BEST when it comes to taking down turrets near level 14-18 using your rapid fire thing (lol that sounded wrong)
= a Kick *** Little Midget Girl or as i like to say it... K.A.L.M.G. + others

THE END
... I'm hungry and i don't want to write anymore
HOPE YOU ENJOYED POS
