Welcome to my Tryndamere build. Tryndamere is my favorite AD carry because of his unbeatable critical chance.This is my first time making a build so sorry if I make any mistakes. Please leave comments when voting so I can improve my build. Enjoy!

Skills:
Battle Fury: This passive is what makes Tryndamere a crit-monster. It increases your critical chance based on the amount of fury you have. You get fury for attacking and bonus fury for critical strikes or killing a unit. Your fury decreases when out of combat for a certain time. Attacking turrets doesn't give you fury but you don't lose fury either. Try to keep your fury up at 100 at all times.

Bloodlust: This ability goes with your Battle Fury passive. Its passive gives you attack damage based on how much health you're missing. Its active heals you based on the amount of fury you have. Use it when you have full fury and are in need of healing or will be out of combat. When using Undying Rage save this to use after Undying Rage ends to save yourself from damage over time abilities or to just heal so you have a better chance of not dying after Undying Rage ends.

Mocking Shout: Mocking shout is what makes you unbeatable by any other AD champions. It reduces enemy champions attack damage and if they are turned away from you they will be slowed. Use this to gank people and chase them. Also use it in team fights to debuff the enemy team. Also great for countering the enemy from pushing your towers. Just mock them while you stay at a safe range to reduce their AD making them unable to kill your tower.

Spinning Slash: Spinning Slash is Tryndameres damage dealing ability. It scales off with your attack damage and does quite a lot of base damage. Use it to chase your opponents, farm, or escape. Its can go through walls so use it to your advantage. Also something that's not mentioned in the ability tool-tip is that every enemy you hit with Spinning Slash gives you 2 fury.

Undying Rage: This is Tryndameres ultimate and one of the best ones in the whole game. For some time you are unable to go lower than 1hp. Use it to save yourself or to win an intense 1v1 fight. Also useful for turret diving safely. Delay the use of this to make your opponents overextend but be careful to not accidentally use it AFTER you DIE! This requires good timing and practice. The later you use it the more time you can't die. Remember to use Bloodlust right when your ult ends. If you don't things such as ignite will kill you.
