Hi Mobafire community, this is my very first build. First of all, I'd like to clarify, that this build uses my personal preferences, and I don't doubt, there are more powerful/useful builds for one of my fav champ, Tristana.
Since I'm not a pro player, all of your feedback is welcomed, and i will consider adding your suggestions.

The reason I started this guide, is because I liked tristana both as AD and AP. Her ratios are awesome, she has very decent abilites, while her range at late level is brutal as an AD. So why not do a hybrid?

This is a work in progress. I'm editing it any time I can get to it.

Well, that's for starters, have fun with my build.

So, let's get started. I ALWAYS start with Boots and three Health Potion, either lane i am on. Why? because it gives you a little sustain, and maneuverability. As soon as I can, I get berserker's graves

After I go for Malady which is an awesome item, for both early and late game (altough lategame I sometimes switch it for a Nashor's Tooth. This item, will give you a nice damaga boost for your autoattacks in magic damage, AP for your abilities and finally attackspeed. What else we need? Approximatelly for the same amount, you could get a B.F. sword with twice the damage boost, but none the others, and they can still buy armor, which negates your damage...
Furthermore, this item, has an awesome passive. It shreds the MR of the opponent, which can stack for 4 times. That equals -24 MR for him. Just smash with your Explosive Shot after a few autoattacks, and half of their HP is down. Awesome.

Next item is Wit's End. It's basicly malady backwards. It will give you MR, and attackspeed, again magic damage to your autoattacks (that's 62 along with malady!!!) and stacks MR for you. Ain't that purely awesome? It gives you and edge over magic users, and if someone checks your stats, he will think, you have only a 100 and sth. damage, for the bonus damage doesn't show there... ;) pretty surprise for them.

The next item is so powerful with this build, I can barely imagine it. Guinsoo's Rageblade. I don't know who guinsoo was, but I wouldn't be next to him when he rages...
It gives us a moderate boost in AP and AD, which is awesome, but we don't buy for this. We buy it because of the awesome passive. It will raise our AP and Attackspeed with each ability use or autoattack, furthermore, it stacks. 8 flippin times. That's 24% boost in AP and AS in literally no time, since we have very cool attack speed already. Yeah, and our autoattacks are lowering the MR of our enemies... They are dead. :D

By this time, we won the game usually, but if we didn't, then we start to get nasty. We buy Rabadon's Deathcap. With the rageblade's passive, it gets pretty wild. After this, (or before, if you'd like) we can buy another very nice littel item, Infinity Edge which will boost our AD and gives us Crit chance, which with our attack speed will occur pretty often.

Well the build is officially finished, I wouldn't change it too much, coz the awesome passive's we gathered, but if you will like you can get a Nashor's Tooth or something like that.

Tristana excells in farming from mid game, with the passive of her E. She can take down a huge minionwave in a matter of seconds. In early game you must last hit as much as you can. Priorize minions with other low HP minions around, so you can get 2-3-4 minions with one last hit if you are careful enough.
Later in the game, your range grows thanks to your passive, so you can easily farm from safety.

If you don't have a jungler, you can venture in to the woods, and kill the wraiths with one rocketjump, and an autoattack. Do it as much as you can, to maximize your gold income

I usually take flash-teleport all the time, but surge serves well with tristana as well. Ignite, Exhaust, Heal, you can take these if you want to, and know how, and when to place them.
You can switch flash, because you have rocket jump, and with that you can escape 90% of the time, I take it, so i can escape another 9% percent :D
