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.
Critical Chance/Damage Build
This build isolates critical for tryndamere which seems to work very well with tryn because it allows him to use bloodlust effectively and he also gets better crit chance as he gets lower hp.
Start of the game tryn should play defence no wild moves or turret diving yet last hit minions and use bloodlust to lane longer because it doesnt cost anything and you have no need of mana than your able to effectively lane. Once your level six you can start playing slightly more aggresive but remeber any decent disable can screw you royally specially stuns and silences because it prevents you from going into endless rage. So about mid game you should be hitting crits at least every other hit maybe even every hit in a row if your lucky and you can destroy your enemies like this. Mid game if build right you should at least have your avarices, calling and a bf sword for infinity edge once edge is complete your crits with normal attacks should be about 450 which will cut down many enemies very fast. So focus the squishies and carrys leave the tanks until the end and be ready to rage and spin out of there with using your bloodlust to heal. By end game you should be able to take down a good few people even without ulting just use bloodlust and your life steal to survive with. Tryn is good at hitting towers and escaping so if you feel like backdooring you can do that quite well with tryn.
