Hello there, all you need to know about this build is, that in late game you'll get 100% crit.chance and 2.5 attack speed (assumed you build the correct items). Those two stats combined along with Navori Quickblades passive mean you can spam your spells pretty much all the time. Regarding the Triumph rune, you could replace it with Presence of Mind if you find yourself struggling running out of mana fast. You'll also get a lot of healing from both auto-attacks and spells. The last item is your item of choice, when there's neither much healing in the enemy team nor there are more than two problematic tanks bothering you, you'd ideally wanna go for crit based last item to achieve that full crit.chance ( Bloodthirster). There isn't really a need to build more attack speed with your last item cause you will reach that sweet 2.5 attack speed by having your Rapid Fire active all the time anyway. That's pretty much it. ٩(◕‿◕)۶ I hope you like this build and give it thumbs up. Have a wonderful day!

- Tristana is well suited for an aggressive playstyle. Most of the time when you win your lane and stomp the enemy bot lane you also win the game. If possible, try to get your bot lane partner to play aggressive support (something with engage like
Leona, Nautilus, Pyke, Alistar, Blitzcrank, Swain, Taric, etc...).
- In early game build Cull when behind or you're having passive lane/ incapable support who can't engage. When in a lane with good support, constantly harass your enemies by using the Explosive Charge and triggering Hail of Blades.
- You might consider playing some other ADCs when either playing with passive support who can't help you engage or playing against enemy bot lane with a lot of CC.
