Hello League of Legends fans,
This site is one of my personal favorites for character builds and I've been using it a lot when I first started playing League of Legends.
It has given me some good ideas of builds to try and develop my personal playstyle and now it's payback time!!!
I want to point out that I'm not a high elo player and that build is the result that came up to me while I was thinking of choosing a main adc.
So sit back,relax and... SUFERRRRR while choosing the latest final item for this build.
I myself succumbed to the power of trinity force... :P
How about you??

Items selection,the core of this guide,choosing the right combination of items is hard especially for a non-standard and unstable type of characters like hybrids.
Since Tristana is supposed to be an adc and a descent life steal is more than a must here.
In the other hand items like and offer a good mix of ability power and attack damage while providing life steal and spell vamp.
Adding a in the mix automatically makes the hybrid adc deal bonus ap damage and provides attack speed that scales well with the passive of and critical of .Also 20% cooldown reduction and ap give a good push to it's ap burst.
is another great item for Tristana that many Tristana players find useless,however Tristana is one of the few players in League of Legends that synergize perfectly with it,her insane attack speed maximizes the armor penetration almost immediately and the 10% cooldown reduction(with or or even a ) caps it at 40% that unlock the hidden assassin potential of ap Tristana.

Due to the incredible powerup of in the latest patches i decided to add it as the last item of this build.
Since this build is about a hybrid character and are also good choices either for slow~safe ranged killing or quick bursting.

However there are some amazing items that are also pretty good choices for the final item.
These either focus on maximizing attack speed like and

Life steal

or both at the same time

Last but not least just like an ordinary adc is also a very good choice and it's highly recommended here.

For summoner spells you can for the standard and .
Other good choices are and if you have trouble 1v1 the enemy adc or apc.
You can also take and if you are arrogant enough or extremely certain that you can get out of battle easily without it.
, and are only recommended for more experienced players and are kinda situational.
still remains a good option for farming early game and surprise ganking but it gets a little useless later on(unless you are willing to backdoor :P).

The ability sequence is upon your own personal preference so it's kinda optional to follow this.Personally I prefer to max explosive shot first in order to be easier to farm and harass,however if you are kinda good in last hitting and don't want to push the lane you can max this skill last when you will have some ap to burn their health and focus in leveling rapid fire.Either way take a point in rocket jump at level 2 to avoid gangs.

Since you are hybrid adc you have a variety of runes you can choose,you can either go for full hybrid penetration thus wrecking up enemy tanks who dare oppose you or use your instinct and choose what fits you best.
Attack Damage,Ability power,magic penetration,armor penetration or even lifesteal are all viable choices however since you play Tristana a character who isn't a normal adc and has her damage issues it would be preferable to use runes that give you either attack damage or armor penetration for marks and quints in order to farm and damage effeciently.
For seals and glyphs you must take durability items since hybrids usually focus on pure stats,armor seals and magic resist glyphs are the way to go(if you are unsure of your late game performance prefer the per level ones)
