Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
When you choose to have fun with Tristana, you must know that she is EPIC. First you Buy doran's blade and a potion, so you can stay longer in line. And when you get your "Explosive shot" in high level, it's very good to deal high Damage. then you get feeded by the minions. and don't think about killing enemy Champions before reaching lvl 6 or 7. When you reach those lvl's, "rocket jump" to the enemy champ, use active "explosive shot" on him. and "exhauset" un him. then you use "rapid fire" then shot him til like 200-250 hp and use ULT!. when you become very feeded. you should run, between the lanes, and just kill other champs, but don't go to close to them, because, tristana gets a very long range, but low hp.
