Tristana Build Guide by Wenvarien

ATTENTION!!!!!!!

I am now a United States Sailor. I graduated from boot camp March 2nd. I know that in my absence the game has made some drastic changes and I will do my best to get my guide updated when I have the time to do so.

Introduction

Hello, my name is Wenvarien. This is my first build on mobafire. Please be courteous and don't troll or down vote my build for no solid reason. I encourage you to at least give the build a play-through before you give positive or negative votes or feedback. Having said that this is simply my take on and how I like to build her. This build may not be for everyone but it suits my play style and I find it very addictive.

I would also like to point out that this guide is very in depth and requires A LOT of reading. So if you don't want to read through what I have to say simply copy the build and wing it :D.

If you like my build or want to give me some pointers/suggestions please do so below and give me the thumbs up if you like it.

I would also like to give everyone a thanks in advance for first taking the time to look at and read through my guide and another thanks for any positive votes. If this guide works for you, post screen shots in your comments and I will gladly put them up.
Another thanks goes out to JhoiJhoi for the line dividers and all of her hard work on her Karthus Guide. Thanks again Jai!

Builds

The first build is a Summoner's Rift build. The guide focuses on this build but much of the information is relevant to whatever map you play on. This build is focused on Dominion. I am currently in the process of going through the details of this build.

Pros and Cons

Pros

• Very strong early game harassment.
• Great at chasing or escaping with the use of Rocket Jump
• Progressively gets longer and longer range with her passive, Draw a Bead
• Great farmer with the use of her Explosive Shot
• Rocket Jump is much like Flash. It can be used to jump over walls, trees, etc.
• Very high attack speed late game.
• Does well in any lane.
• Easy to play.

Cons

• Can be very squishy, this depends on item selection.
• Very little mana.
• Vulnerable to Thornmail.
• Slow movement speed.
• Item dependent.
• Ultimate can easily be used wrong because of knock back.
• Difficult to master.

Masteries

Here I'm going to walk you through each tier and explain why I picked the masteries I did. The first tree we shall delve down isOffense. The second is Utility.



In the first tier there are honestly only 2 options that prove viable with the summoner spells in this build. Those 2 would be Brute Force and Summoner's Wrath . So you max Brute Force first for the higher attack damage. Then put 1 point into Summoner's Wrath so you can gain access to the second row, it benefits Ignite. If you prefer Exhaust over Ignite, Summoner's Wrath thankfully benefits both of these.


Start off by maxing Alacrity . The 6% increased attack speed helps maximize your DPS(Damage Per Second). Sorcery doesn't benefit Tristana so there is no need to get this. Demolitionist isn't needed on Tristana either. So the choice is obvious.


In tier 3 you want to grab Weapon Expertise for the armor penetration. Next you max Deadliness . This 4% from Deadliness boosts your end game Critical Strike chance to 89%.


Tier 4 is pretty self-explanatory. You can't access Blast so the only other options are Vampirism and Lethality . Both of these greatly benefit Tristana, so max them both. Lethality boosts our critical strike damage to 260% with an Infinity Edge.


Tier 5 is also self-explanatory. Sunder is by far the greater choice over Archmage . Sunder gives you 6 points of armor penetration which, coupled with the 9x Greater Marks of Desolation, and the 3x Greater Quintessence of Desolation brings your armor penetration to a whopping 30.93. This much armor penetration can turn your early game damage into true damage against any champion, with the exception of item selection and masteries/runes.


Tier 6. Executioner . 6% extra damage to champions below 40% health is impossible not to love. That's our 21 points into Offense. Next comes the last 9 points in the Utility Tree.





In the first tier we want 3 points into Good Hands . The 10% reduced time dead can really be a game changer. Put your next point into Summoner's Insight for the reduced cooldown on Flash. 4 points down 5 to go.


This tier should be a no brainer. You can only access 2 of the 3 masteries. So you're going to want to put the 4 points into Swiftness to help Tristana's slow movement speed and put your last point into Runic Affinity . Take advantage of this point and try and get the red and blue buff when you can.

Runes

9x Greater Mark of Desolation 9 of these helps you rip through enemy champs early game and is the best mark for . Simply put armor penetration = more damage. Who doesn't want that?? 9 of these give you 15 armor penetration. This is enough armor penetration to get through almost all of the champions' base armor. If you couple this with the Offensive masteries and the Greater Quintessence of Desolation you will be doing true damage to any champion early game with the exception of runes and item selection. The Greater Mark of Desolation help you throughout the whole game. Early, mid and late.

• 9x Greater Mark of Attack Damage for higher damage. This benefits you the most early game but the armor penetration gives you a better output.
• 9x Greater Mark of Attack Speed for faster attack speed. This isn't really needed but is a decent choice if this is what you prefer.

9x Greater Seal of Armor 9 of these gives you early game armor and better survivability through the game. I know that 9x Greater Seal of Defense has a better turnout at level 10 but I personally prefer the early game armor. Both are good choices for survival.

• 9x Greater Seal of Scaling Mana Regeneration and 9x Greater Seal of Replenishment are both good choices if you don't like dealing with Tristana's mana problem.
• 9x Greater Seal of Vitality, these are also a good choice instead of the Greater Seal of Armor. Tristana is very squishy and 9 of these will help you be a little less squishy.

9x Greater Glyph of Magic Resist. You can't have armor without magic resistance if you want that survivability. 9 of these help your early game magic resistance and just like the armor seals the turnout on the Greater Glyph of Scaling Magic Resist comes at level 10. Again I prefer the early game magic resistance, but it is up to you.

• 9x Greater Glyph of Cooldown Reduction and 9x Greater Glyph of Scaling Cooldown Reduction are decent picks if you don't want the magic resistance. Both of these can allow you to spam your abilities alot more, which can be very useful, seeing as all of Tristana's abilities have very long cooldowns.
• 9x Greater Glyph of Scaling Mana Regeneration is another decent pick if you believe you need the higher mana regen.
• 9x Greater Glyph of Attack Speed are decent picks as well. The attack speed isn't really needed though because of the item selection and Rapid Fire.

3x Greater Quintessence of Desolation or 3x Greater Quintessence of Health. These 2 would be my personal top 2 picks for quints, but to me, the Greater Quintessence of Desolation is the best choice. More armor penetration again = more damage. But more health early game makes you that much harder to kill and lets you lane a little longer. This is always a plus.

• 3x Greater Quintessence of Attack Damage for extra damage during early game.
• 3x Greater Quintessence of Movement Speed to help Tristana's horribly slow movement speed.

Summoner Spells

Flash is arguably one of the best summoner spells. Although it went through a pretty heavy nerf, Flash still has many uses. You can Flash over walls, trees, etc. Flash is also a great chaser or closer as well as a good escape mechanism. Ignite is a very powerful summoner spell. Ignite makes it very easy to pick up first blood or a kill in the first few minutes of the match. Ignite is also very useful in countering any champion who has life steal or spell vamp, such as Dr. Mundo, Warwick, Vladimir etc. Be wary that it can be removed by Cleanse. Exhaust is another great summoner spell. Exhaust can very easily turn a 1v1 in your favor. It's not only a offensive spell but can be used defensively if need be. Exhaust is a great way to stop enemy champions in their tracks so use it wisely. Crowstorm, Absolute Zero, Death Lotus etc. are all easily mitigated with the use of [Exhaust. Be wary Exhaust can be removed by Cleanse Ghost is a good replacement for Flash. Ghost is a good escape mechanism and a good closer. I find it less reliable then Flash but Flash is not always easily used and can get you killed. If you have difficulty using Flash pick up Ghost instead. Be wary of slows or stuns because you can still be affected by them under the effects of Ghost. Teleport requires a lot of map awareness to be really useful. It has many uses from switching lanes quickly to save a tower, set up a gank, or even return to your lane after a recall for minimal time lost. While Teleport has its uses it doesn't mean that you will always get a chance to take the full benefit from it. Heal is the face roll summoner spell. While it is considered a "noob" ability it has its uses BUT is a better choice for a tank or support. This is a very good option for lower level summoners who haven't accessed Flash or Ignite yet. Cleanse is a great defensive spell. While I wouldn't take it over Flash or Ignite, if you are facing a heavy CC team then it might be worth the investment to grab it. Remember Cleanse removes all CC effects with the exception of suppresion. It also removes Exhaust and Ignite.

• Smite is not a good choice. Period. You are not jungling as Tristana so don't take this spell.
• Revive is a bad choice. You are aiming to stay alive and shouldn't have to rely on Revive to get you back in the game. If you are dying enough to need Revive you are doing something wrong.
• Clairvoyance is better left to the supports. Try and avoid taking Clairvoyance while it does have its uses you are the CARRY and as such you shouldn't be the one to take Clairvoyance.
• Surge only has one use for AD Tristana.....the extra attack speed but why waste a valuable summoner spell pick when you can simply take advantage of Rapid Fire. Surge is not a good pick. Avoid it if possible.
• Promote.......to put it simply......don't take Promote. You should have no need of a giant cannon minion.

Ability Explanations, Level Up Sequence, and A Few Tips Mixed in.

In this section I will explain Tristana's abilities and the order I prefer to level them up.

This is Tristana's passive. Tristana starts off with a small 550 range. While this outdistances some champions, she falls around the middle of the pack when all the ranged champions are lined up. Every level that you earn, you're range goes up by 9. Caitlyn has the highest starting range of ALL champions. BY level 13, Tristana out ranges Caitlyn. By level 18 your range is 703. There are only 2 champions that can get more range than this: Kog'Maw has a range of 750 when he maxes Bio-Arcane Barrage, and Twitch , whose range is 875 when he uses Spray and Pray. Tristana has the highest auto attack range end game, thanks to her passive. This makes chasing down enemy champions that much easier. Use this range to your advantage.
This ability pushes Tristana's attack speed to the cap of 2.5 late game. It also helps you win those close battles and overall simply increases the max damage you're able to dish out. This is a great way to burn through multiple squishies or through that pesky tank. Rapid Fire is also a very good way to destroy turrets, inhibitors, or even the enemy's nexus very quickly. BUT be wary of Thornmail. DO NOT use this ability on anyone that has Thornmail. Even with The Bloodthirster maxed out you WILL kill yourself faster than you are able to steal your life back.
Probably Tristana's most useful ability. As mentioned before, this ability can function much like Flash. You can Rocket Jump over walls, trees, and most obstacles in your path. It can also give you that little boost ahead of anyone chasing you to allow you to make it safely away. Use it to clear harmful abilities from enemy champions. For example, if Nunu caught you in his Absolute Zero, Rocket Jump out of there and move those little legs as fast as you can. So it can be used defensively, but it also can be used offensively. Rocket Jump after someone if they are running away. Rocket Jump onto a squishy and blow them up before they can get away. Did Ashe just Flash through some trees to get away? Rocket Jump after her and possibly hit her or even pick up a kill in the fog of war. Rocket Jump has many uses. Simply be smart in its usage. Don't Rocket Jump into the middle of a team fight. Use your range to your advantage and save Rocket Jump to pick up a kill or get out of dodge. This ability is how Tristana is so effective at clearing minion waves. The passive rips through minion waves in mere seconds at high levels. Take advantage of the passive. If there is an enemy champion standing near low health minions, attack the minions so that enemy champion takes the exploding magic damage from it. The active on this ability is a good way to pick up a kill if you think the champion can get away from you. Simply drop it on them at low health and watch their life tick away. One of the best times to use it is when Tryndamere uses Undying Rage; both last for 5 seconds. So once he activates it, simply wait a second or two and then drop Explosive Shot on him and walk away. 9 times out of 10 this will kill him. This is also your early game harassment ability. Tristana's ultimate. Very fun ultimate to throw around, and the cooldown isn't horrible. It's not only fun, but can be used both offensively and defensively. BUT be mindful that while Buster Shot can help you, it can also very easily hurt you. If you're chasing an enemy champion, DO NOT use Buster Shot unless you are 110% positive it will pick up the kill. The reason behind this is after Buster Shot does its damage, your target gets knocked back a distance of 600 at level 6, which is farther than your auto attack, 800 at level 11, which is higher than your auto attack even at level 18, and a HUGE 1000 distance maxed out. So unless you're positive you can pick up the kill, do not use this in a chase. It will blow your target well out of your range and cost you a kill and possibly a few remarks from your teammates. The proper way to use Buster Shot is to get in front of your target by either surprise, or simply Rocket Jump on top of them, hustle over in front of them, then Buster Shot. This is a good way to knock back fleeing champions into your teammates or simply push them farther back so you can pick them off as they run towards you. It's also possible to hit multiple champions into your team or separate their team. Just aim for clumped targets and let her rip. Defensively, Buster Shot shines just as much as offensively. Instead of maneuvering around the enemy to blow them backwards, all you have to do is turn around, shoot, watch them fly off, then turn back around and high tail it. Buster Shot is a great way to get the enemy off your back or your allies back. If Rocket Jump is on cooldown or you just can't get out of dodge, a carefully aimed Buster Shot can make getting away simple. Another great defensive mechanism of Buster Shot is being able to interrupt an enemy champion's channel. Katarina's Death Lotus, Nunu's Absolute Zero, or Fiddlesticks' Crowstorm, along with any other enemy champion's channeling ability. So remember the multitude of ways you can use your ultimate and make sure you use it right.
On to the leveling up sequence.

Items

YAY!!!!! ITEMS!!!!! :D

An all-around great starter item for Tristana. The extra AD is always an added bonus. Gotta have damage to pick up kills after all. The 100 HP is also a blessing, seeing as Tristana is extremely squishy throughout the game, so a little early game survivability never hurt. The 3% life steal, while a very small percentage, is just icing on the cake. It might only be 3%, but that 3% helps you get your health back just a little bit faster. As you progress later into the game and the build starts to come together, sell this when you need the room. On your first trip back to base, you should buy these if you have the money at the time. Unfortunately, Tristana's base move speed is only 300, which is extremely slow. The boots help fix that. That little bit of extra speed makes a difference in trying to get away from the enemy or hunt that enemy down. On your next trip back to base, make sure you have at least 450 gold to buy the Vampiric Scepter needed for Wriggles Lantern. If you have enough to buy either the Cloth Armor or Long Sword, pick one or both of those up, or even Madred's Razors if you can afford it. Then finally put your Wriggle's Lantern together A.S.A.P. The added damage from this helps pick up those kills and helps you last hit minions. The 30 armor is a great benefit simply for more survivability. More armor = less damage. The 15% life steal coupled with the 3% from Doran's Blade and the 3% from Vampirism gives you 21%, which makes it much easier for you to keep your health up and lane even longer. Do not forget to use your free Sight Ward from Wriggle's Lantern.



This is where you should ward with your Wriggle's Lantern.
Yellow: Vital to protect the jungler on your team
Blue: For protection depending on which lane you're in
Red: To guard Dragon and Baron
Orange: In order to Counter-Jungle After you obtain your Wriggle's Lantern, work up to getting enough gold to buy the Berserker's Greaves. These increase your movement speed greatly on Tristana, seeing as she is still slow with the Boots of Speed, and it increases your attack speed, which means more DPS(Damage Per Second). Work your way to getting the Infinity Edge as fast as you can. This is your big boost in power. The damage it provides is essential and it gives you a higher critical strike chance which we want. It also increases your critical strike damage up to 250%, which, on top of your masteries puts your critical strike damage at 260%. This is one of Tristana's most important items. Now that you have boosted your damage to nice levels, you need to get your attack speed higher and your critical strike chance even higher. The perfect item to do that with is the Phantom Dancer. The extra movement speed that the Phantom Dancer also grants is just more icing on the cake. Put your Phantom Dancer together piece by piece. Each piece will affect you positively. By this time, you're gonna want to get more life steal to help sustain yourself better. The Bloodthirster is the best way to get the life steal you so desperately need by now. If you need any extra room to pick this item up, sell Doran's Blade. Make sure you farm The Bloodthirster up before trying to throw yourself at enemies. Now for that extra armor penetration, pick up The Black Cleaver when money permits. This is also the point where you need to sell your Wriggle's Lantern to make room. The attack speed from The Black Cleaver boosts your DPS as well as the added damage, and you will now be able to land all 3 stacks from The Black Cleaver in seconds. You're going to want to get a Guardian Angel to boost both your armor and magic resistance to help your survivability. When you do this is up to you. You can do it earlier if you are having a hard time surviving and need the extra armor and magic resistance or do it later in the game. After you obtain Guardian Angel, you're gonna need to pick up another Phantom Dancer. You're grabbing the second one for the same reasons as the first. Besides, good things come in twos. More attack speed and critical strike chance mean a higher DPS. The movement speed is just the cherry on a sundae. You are going to have to sell your Berserker's Greaves to make room for this but the trade off is worth it. Chances are you won't get to this point of the game but if you do this is the item to get.

Optional/Situational Items

Who should I lane with?

Sometimes you don't always get a choice of who you want to lane with, but sometimes you do get a choice. There are certain champions as Tristana that you should really want to lane with over others, and I'm going to tell you about those certain champions.

Alistar is a good lane partner. He is naturally beefy (no pun intended LOL) and makes for a good meat shield. Alistar's Pulverize + Headbutt combo can make for some very easy kills for both of you. Not only that, but Triumphant Roar makes it very easy to stay in lane as long as possible.
Amumu is a good choice as a lane partner. The stun from Bandage Toss makes it easy to pick up kills and Curse of the Sad Mummy coupled with your Rapid Fire can be devastating to your target. Unfortunately Amumu is not the best meat shield during early game so be mindful of that.
Blitzcrank isn't naturally beefy but he makes a good lane partner. While he isn't the best meat shield if Rocket Grab and Power Fist are used properly it can be nigh impossible to escape from the both of you. Make sure to exploit this if you do lane with him.
Cho'Gath is a natural meat shield no matter how he decides to build. He has a very large amount of HP so take advantage of this and hide behind him. Try and take advantage of the knock up from Rupture as this is an easy way to do a lot of damage rather quickly. Feral Scream can also make it difficult to lane against the both of you.
Dr. Mundo is a good meat shield seeing as he is built with a lot of hp. He makes a good laning partner if you need someone to hide behind. Take advantage of Dr. Mundo's slow from Infected Cleaver if you lane with him.
Galio is a very nice champion to lane against. All of his abilities benefit you and make getting kills much easier. Galio is also built tanky making him a good meat shield. Do not be afraid to go out of your way to lane with a Galio if you get the chance.
Garen is a good lane partner as well. While he doesn't have any abilities that benefit Tristana greatly he has very high hit points and can take a beating. Garen makes a good lane partner because of this. He is very hard to bring down and can lane for a very long time. Take advantage of this. DEMACIA!!!!
Gragas is not the best laning partner but I chose to put him up here because he is sometimes played as a tank. He is naturally beefy and thanks to Drunken Rage can take a beating. If you do lane with Gragas make sure he is going tank. You DO NOT want to lane with AP Gragas because he can clear minion waves very quickly and will hog a lot of the minions. So tank Gragas is good and AP Gragas is bad, remember this.
Janna while not a meat shield is a very good lane partner, in that she can babysit you the whole time. Eye Of The Storm is what makes Janna a good lane partner. Make sure you ask whoever it is that is playing her to keep this shield on you as much as possible. Also take advantage of the nice slow from Zephyr.
DEMACIA!!!! Jarvan IV makes a good lane partner. While he is not always centered on being a tank even an off tank Jarvan IV makes a good lane partner. He is naturally beefy and can take quite a beating. Demacian Standard is just awesome and boosts your AD quite nicely. Dragon Strike plus Demacian Standard provides a nice knock up allowing you to get a few shots in. On top of that the slow from Golden Aegis can make it very difficult for anyone to escape and Cataclysm clinches that chance even more. Jarvan IV has lots of advantages he can provide make sure you exploit these.
Leona is a decent lane partner. While she is not naturally beefy she is a tank and eventually reaches the beefiness that tanks require. Shield of Daybreak has a nice stun that can make getting kills easy as well as Leona's ultimate Solar Flare. While she is not the best lane partner, neither should you shy away from laning with her.
Malphite is a "rock solid" lane partner. Malphite is the perfect harasser with use of Seismic Shard. The slow from this also is very beneficial to getting those kills. Malphite is naturally beefy and is very tough to bring down. Seismic Shard is not the only ability that makes getting kills easy. Upon hitting level 6 Unstoppable Force can make getting away very difficult for your opponents.
Maokai can be a good lane partner or a bad lane partner. If you do lane with Maokai come to an agreement with him about not hogging minion waves with the use of Sapling Toss. If an agreement is reached Maokai can become a great partner to lane with thanks to his natural tankyness and the use of both Twisted Advance and Arcane Smash. Use these to net a couple of kills if possible.
Mordekaiser is a good champion to lane with. While none of his abilities have a CC effect that benefits you he is normally built tanky with a lot of hit points because of this Mordekaiser makes a good meat shield and can be a good person to hide behind in lane.
Nunu is a good choice for a lane partner. He is naturally beefy and can sustain himself in lane for a very long time. Nunu is generally built like an off-tank so he makes a very good lane partner to hide behind. Blood Boil if used properly can allow you both to dominate a lane as well. Ice Blast is another reason why Nunu becomes a good lane partner. The strength and duration on the slow from Ice Blast can make it very difficult to get away from the both of you and should be able to net you some early game kills nicely.
Olaf is a good choice to lane with if he is not jungling. Olaf is built with a lot if hit points most of the time to make up for Reckless Swings. Undertow is the only ability that really helps Tristana but Olaf still makes a good lane partner.
Rammus is a good lane partner although he can be fairly squishy early game. Rammus is a tank. Period. Puncturing Taunt and Powerball can make it very difficult to get away from the both of you if used properly. With good communication Rammus can be a great lane partner. Just remember that he can be squishy early game.
Shen is arguably one of the best tanks in the game. Shen has several abilities that can be useful these being Vorpal Blade, Shadow Dash, and Stand United. Make sure you take advantage of the taunt from Shadow Dash and the healing effects from Vorpal Blade.
Singed can be a great lane partner or a very horrible one. The use of Fling and Mega Adhesive can make Singed a great lane partner by making it almost impossible to escape from both of you. On the other hand, Poison Trail can very easily make Singed a bad lane partner if he uses it in excess and takes all the minions. Make sure you come to an agreement about this if you lane with Singed.
Sion while not as beefy as some of the other choices for a lane partner still makes a good one. The major reason behind that is Cryptic Gaze. The 1.5 second stun from this can decimate your enemy if you focus fire the stunned target. This is the biggest reason why Sion is a good lane partner and with good communication it should be fairly easy to pick up kills.
Sona is a good babysitter. She is very squishy so she can't be a meat shield for you, but she can sustain you and help you stay in lane as long as possible with Aria of Perseverance. Crescendo can also help you net some kills if used properly. Just be mindful that Sona is very squishy and you are both very prone to ganks. So keep your eye on that map when laning with Sona.
Soraka much like Sona makes a good babysitter. Also like Sona she is very squishy. Soraka has the ability to keep you in lane for extended amounts of time with Infuse and Astral Blessing. ON the other hand, Soraka while a good babysitter, puts most of the pressure on you to pick up the kills.
Fabulous Taric can easily be the perfect lane partner. Taric can be rather tanky and still do good amounts of damage and still be able to support you as well. The stun from Dazzle can make it easy to pick up kills and the extra armor from Shatter makes you both much more durable against any AD champ. Imbue is a nice heal and can make both of you stay in lane longer than your counterparts. The aura from Radiance is also very handy in a fight and can make a difference in a battle. Taric is a great lane partner overall.
Volibear is a good laning partner. Volibear builds with a lot of HP to take advantage of his passive, Chosen of the Storm and Frenzy. This is what makes him a good laning partner on top of his other 2 abilities; Rolling Thunder and Majestic Roar.
Yorick is a beefy champion that can make a decent lane partner. While he only has one ability that really helps you he is a decent meat shield. Omen of Pestilence is that ability. The slow while not the most reliable is a slow none the less and can help you both.

So overall the best lane partners for Tristana are someone with a good amount of crowd control effects, someone beefy that can take some punishment, or someone who can babysit her. Remember this and try and stick with the right people. Having said that this is certainly not set in stone. While these are all good lane partners this doesn't mean that you and Veigar laning together is automatically going to be bad.

Game Play (open for suggestions)

No matter what lane you're in focus on last hitting minions. Plain and simple you need to farm as much as possible so that you can afford the build. Focus more on farming then harassing but if the opportunity presents itself to harass your lane opponent use Explosive Shot and auto-attacks when they get in range. Don't go out of your way to land Explosive Shot at lower levels because Tristana is very squishy. NEVER FACE CHECK. Bad things happen when squishy champions face check.
Continue to last hit minions and farm up more and more gold. By this point you should have acquired some items and you can be more aggressive but don't be over aggressive. If your lane is doing well consider ganking other lanes. Make sure you communicate with whoever's lane you are ganking and synergize your timing. Use Rocket Jump to get behind your target and quickly use Buster Shot after that to push them back into your ally. If your team doesn't have a jungler and no one is taking advantage of the red and blue buff grab them when you have the time to do so.
Continue farming and pushing lanes when it is safe to do so. Also continue to grab the blue and red buff if they are open. But most importantly try to be there for the team fights that will happen. As Tristana, your positioning and target in team fights is paramount.
Whom you should focus in a team fight in order of importance:

• Any AD or AP carry within range. Pick the deadliest champion first, or whoever your team called the focus fire on.
• Any Support champion that is in your range. I.e., Sona, Soraka, and Janna.
• Any AP/AD melee champion that is within range.
• Any AP/AD ranged champion that is withing range.
• The teams tank. This should always be your last target in a team fight.

As for positioning you want to stay where any ranged AD carry should, behind your tank and any melee champions that you have. Remeber Tristana has massive range late game and now is the time to take advantage of that. Try and position yourself away from the main mass of bodies but behind your melees and use your range to try and pick off the supports, and any AP/AD carries that are in range. Do not use Rocket Jump into the middle of the fight. This is a very quick way to wind up back in your base after a long wait. For the most part all you want to do in a team fight is pick a target and auto-attack. Save your abilities for the end of the team fight and use them to clean up the stragglers or use them to get out of dodge if you lost the battle.

I'm not sure what else needs to be said. If anyone has any suggestions or ideas that they think should be added into the section please leave me a comment.

Scores

Dominion Guide (under construction)

Seeing as this guides main focus is playing Tristana in a 5v5 situation, and not Dominion, I will be brief in this section.

The mastery set up for Dominion is much like the 5v5 set up. The only difference being the 3 points into Havoc for more damage and the 3 points into both Hardiness and Resistance . You want to take as much from the Offensive mastery tree as you can to benefit your damage and the defense tree for more survivability. The reasoning behind this is because Dominion games are very short and you want to be able to stay alive and deal as much damage as you can so you can keep and cap points.

Summary

This is the end of my AD Tristana guide. Remember that Tristana is squishy all game unless you build more defensively. I would also like to thank you for taking the time to read this guide. Please vote if you liked the build and guide, and give me feedback. If you don't like the build or guide for any reason, please explain why or tell me what you think should be added in. I will gladly put in any screen shots or any suggestions into the build when the time permits. Thank you again.
