Hey guys, this is BR Noturc. Now, I mainly made this mostly for the build and not really the guide. The guide will be brief, but read on.

Those of you new to Tryndamere, he isn't very hard to play.
My advice to you is that if you like melee, AD, DPS champions, why not play Tryndamere?
He can spin through walls, he has a slow, and he can combat heal pretty rapidly at late game.

Also, I advise you that any champion you want to play, please go into a custom game VS an AI or a friend so that you can get a better feel of how he plays.

At first, you should buy:

Why? Because you have 475 gold, the Brawler's Gloves gives some crit, and later on turns into the Executioner's Calling
The Health Potions are just for extra health for while you are in your lane... You would hate to go back constantly, right?

Next, after the first three items, you should buy:

The Vampiric Scepter goes first, therefore turning into the Executioner's calling.

WHY GET IT, YOU ASK?

A little bit of life steal goes A LONG WAY!
With Tryndamere's Bloodlust and life steal combined, he will be able to last in the lane forever, and if you ever play against another Tryndamere, you will have the advantage.
**PLUS** IT'S CHEAP! It'd be silly not to get it.

The next two items would be there:
