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.
I have this build so that Tryndamere gets a lot of critical chances as well as hits hard with damage. I also have him to be able to move fast from place to place. ofcoure if you need a little more help in a fight you have exhaust and a little dodge. The last thing you have up your sleeve is able to heal after every hit. The last thing you cant foget is that its all up to the game as to what items you get but for the most part the order i have it should be fine.
