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.
Tryndamere is designed for the double, triple or more kill. His passive is great for this. when he gets lower heath the more likely he is to critical strike. This build makes it almost a 100% chance that he will critical even if he is at full heath.
Very high damage and critical strike chance.
Very fast so you can get away and chase down enemies.
Fairly low heath for a carry
Hard to play early in game
