not bad :)

If u will work on your build and improve it, i will change my vote :)

I will not down vote!! becase this guide have some great things about it, and it is really in depth and informative... BUT
I have so many probelems with this build:
-Yoummu's. NO! its only worth buying it on on melee champ. You aren't utilizing it to it's full potential- u are basically wasting money! and also u compare it to phantoms. first, phantoms is better, second, i wouldn't buy Phantoms too.Trist already has the strongest AS steroid in the game, so focusing on AD/Crit is better for her. the mobility is nice ofc, but she is already very mobile with her w.
- I would not get Youmu's, also take Flat AD quints instead of Arp because they are better on Autoattacks champs with crit builds, and then get Last whisper or black cleaver at some point of the game, depends on the game ofc.
- im not so sure that frozen malet is a good pick.
-your masteries... You dont take 15% spell penetration, although Trist got 3 abilities that does magic damage. You also put 3 in Preservance. and u wrote "I genuinely don't know what you're referring to here", to the guy who told you that its a useless mastry. Let me expalin, why its so usless .It only increase your health/mana regen, not stuff like heals or life steal. it sux.
- You dont have a chapter for skill sequence, although u have a pretty unusual one.
-with doran stacking i totaly agree. runes are also fine. i would just replace the quints as i said.

You know what, after seeing all this things, im gonna have to -1 sry...

not voting on this one as it has ups and downs imo

Im glad to see someone who uses multi-dorans. And also how you rush inf edge, as it is by far the best item for Trist in the beginning (tired of seeing madreds)

Also you know that you need survivabilty, and some armor pen, which is also good to see :P

You should really do Rapid Fire earlier though, for early kills you really don't need rocket jump past 1, especially if you pop your exhaust (I use ignite, but exhaust is just as effective for killing, I used to use it)

Someone mentioned that you have too much survivability. I agree, somewhat, but you do NEED some. I usually go Frozen Mallet if they are AD, and Banshees if they are MD, and get a bloodthirster for the lifesteal.

Another thing I want to point out is Phantoms vs Youmuu's
Youmuu's will give you a bit better of a burst in dps BUT phantom is consistant, and will constantly be in effect. You'd be lying if you said you've never been attacked while youmuu's was on CD and died :/

ooh and you don't need the ms for escapes, but it still helps with getting around the map, keeping up with your allies, chasing, or if you want to escape without blowing flash
Also if you get 2 you don't need boots ;)

and to counteract the loss of Ar pen from the ghostblade, the black cleaver goes nicely. your high AS lets it proc very quick, and if you have other AD on your team you'll be helping them too!

In any case I'm just offering suggestions :P

By the way, I mourne for you never finishing your build, it's sad :'(

Infinity edge, Bloodthirster, Frozen Mallet, Black Cleaver, and 2 Phantoms (don't need boots with Phantoms) AND all 4 elixers

You are unstoppable ;D

Anywho, nice build, glad to see something that isnt:
Madreds, phantom, bloddthirster, bloodthirster, bloodthirster, inf edge. and then they scream that they need no boots cause they have 1 phantom, and jumps and stuff :/

Nice build mate =]

very nice

First I'd like to say that Tristana has some huge mana problems early game during laning phase, and that without your the seal of mana regen you either are gonna take huge risk ( not having mana to rocket jump) or you are gonna have to blue pill quite often (early game anyway), losing exp and gold. Also I notice you invest in Q as the last skill, but it's importance should not be ignored as it is your ONLY boost to speed till you get Yoummu (which is after 3dorans,boots and infinity so just a bit after mid game if you farmed well). So basically what you would have(b4 youmu's) is great damage and health from 3 dorans and infinity but no attack speed to back that up.

That's just my opinion, I hope you will take that into account as you continu updating your build. Which I am sure youll do as I can see you put a lot work in it.

Solid guide, though spending over 1,2k on doran's blade's is not something i do. one is enough and the other 900g can go to something else. it's a waste of money imo.

you've put alot of time into your build, very solid and well eplxained. +1

You are true about Youmuu!

+1
but fix that issue with your bbcodes at runes and masteries. you have to write [*icon=... size=...]
without *, obviously

Good guide, I love Tristana. Only of the only Ranged AD Carries that I have respect for, (along with Koggy)
Anyway. You may want to fix the grammar to be more consistent with the tooltip in your section where you mention using flash+Rocket Jump to get a kill. Getting a Kill/Assist refreshes the cooldown on Rocket Jump. :p

+1

okay ive been a so called newbie for so long and ive always refused to get a ghostblade or a deathfire grasp granted i only have 400 wins i just havent taken the time to try them yet but congratulations you have changed my mind. I like your build alot and im going to try it out right now, i need some practice on trist so either way good or bad im giving u a +1 because of how much i love what ur build says.
