Welcome to Our Tryndamere guide! This will be my first guide so expect no fancy layout. As you may or may not know, Tryndamere is a melee carry. Many will build straight crit, rushing phantom dancers. While this will work to a point, if an enemy builds some armor, it will deminish your damage output. I Will try to help you improve your gameplay and experiance while playing Tryndamere.

Flash - Not a must for those Tryndamere's who know what they are doing, but the added mobility is vital for those not familiar with his Spinning slash.
Exhaust - Because Tryndamere has such high damage output, ignite is almost wasted on him, and a large problem Tryndamere's will have late game is ranged running from him, Exhaust is a good choice.
Cleanse - A Noteable choice that is really helpful in any situation, since every team composition will have SOME form of CC.

Pros-
Good Farming
Good Pushing
Good Ganking
Great Damage
High mobility
Short cooldown, AoE Slow

Cons-
Rammus
Teemo
Will be CC'ed constantly

The skill sequence involves maxing out your Q, Bloodlust for the sustain in lane, clutch heal in a teamfight, and the added Attack Damage that comes from it.
Q > E > W will allow you to get extra attack damage, self heal, slow, and have a mobility move by level 3.
After maxing your Bloodlust(Q), go ahead and max your Spinning Slash(E) for the extra farming capabilities and added mobility in team fights.

Rather than go with two phantom dancers or rushing a phantom dancer to start, This build beings with an avarice blade, the Gold per 5 from it being helpful until you buy the Youmuu's , and the crit obviously helping Tryndamere. Having an Avarice Blade and a Zeal provides you with the crit, movement speed, gold income, and attack speed you need before you buy any major attack damage. The Youmuu's in place of a second Phantom dancer will grant you with Armor pen, attack damage, crit, and CDR, as well as a Use effect that grants movement speed and attack speed, useful for chasing down enemies, or even running away.

Tryndamere is largely item dependant and so you need to kill those minions. Tryndamere unlike many others hits so hard that last hitting is easy to do, and by end game entire minion waves will bow before your sword. Balancing out farming and harassing early game can sometimes be hard for people who just want to kill everything, but last hitting IS important.

Tryndamere is a great champion to play, not only because of his high damage output late game, but also because of his abilities contribution to the team. His Spinning slash and crit are just plain fun to play and though people may say that Tryndamere is Over powered, I challenge you to find someone who has not played Tryndamere in at least One game.
