Tryndamere is an extremely offensive character with the ability to melt opponents. Not much is going to get in the way of a fed Tryndamere. This build will lead you to victory if used smartly and correctly.

Tryndamere's abilityy to melt is solely based on his attack speed, damage, and critical chance. Giving Tryndamere as much of a bonus in these as possible is always a good choice. Plus the bonus eliminates the need for some items, attack speed especially.

An extremely offensive character calls for extremely offensive masteries. The masteries give Tryndamere further added critical chance, damage and attack speed. Also the little bit of added armor makes him that less squishy.

The items in this build should be followed almost exactly until the last item. The last item is your choice and can vary depending on the game. For the last item, use whatever you think would be of a greatest asset to you.

Getting Spinning Slash first can be very useful in early game as a tool to catch up to an escaping enemy, or it can be used to escape. Then, maxing out Bloodlust first is key, the bonus damage and ability to gain health can be a life saver almost 100% of the time. Then going for mocking shout will be very helpful in chasing down enemies for you and your team.

The summoner spells with Tryndamere have to be used very specifically if you want a kill. For exhaust, you would first want to use Spinning Slash to get in range for mocking shout, if you aren't in range already. Then use Mocking Shout to catch up to the enemy further. After then, you would exhaust them so that you can get the kill. If it's a close call for both of you, use ignite to ensure a kill and a safe get away.

Tryndamere is a VERY powerful champion if used correctly. This build will surely lead you to certain victory. Some say Tryndamere ruins the Twisted Treeline, I say use your resources intelligently.
