My summoner name is iCin and I've been playing League of Legends for quite some time. I play different champions, not one of those FOTM players or tier one champions only --meet my Tryndamere guide/build.

Complex rune page inc.

9x Greater Mark of Malice.
9x Greater Seal of Malice.
9x Greater Glyph of Malice.

3x Greater Quintessence of Malice.

20% additional critical strike.

Standard 21/0/9, no need to type all that nonsense out.

You'll begin with a Brawler's Glove and two health potions. The goal here is a quick Avarice Blade to get maximum benefits from it, so hopefully your lane be it solo or duo bot(never mid) gets first blood or a simple kill and you can quickly back and pick up the additional critical strike and gold per ten.

Normally I'd grab a second Avarice Blade, but with the uniqueness being added to the items(sad face) you'll want Boots of Speed(lvl 1 boots not to be confused with Swiftness) and a Zeal. If you have leftover gold after the Zeal purchase buy an additionally Brawler's Glove for a second Zeal, but do not complete it yet.

After the first Zeal is complete you'll want to rush the famous Infinity Blade. BF Sword or Cloak of Agility --this may sound bizarre, but I feel that some games my critical strike chance is being 'generous', so it allows me to grab the BF Sword. Granted I'm pretty good at last hitting on Tryndamere so to me it does not matter. Either are good, but this must be completed as soon as possible. I normally have it finished by 18 minutes into the game and this is something you should strive for, too.

Afterwards complete the second Zeal and here comes the kicker --grab dat Warmog's Armor. Now you probably just face palmed, but this item is ridiculously good. I was playing a ranked game with Mr. Tryndamere(I maintain a 75%+ win rate with him) and I was getting focused heavily after an early game rape. I had too much farm and too many kills, but they had a double exhaust combination that just shut me down. So instead of losing with my unskilled team, I made sure I had 100% critical strike and an Infinity Edge and purchased not one, but two Warmogs. 5,000 health never looked so good.

Prior to The Bloodthirster upgrade those Zeal's into Phantom Dancer's and you're good to go of course.
Greetings, Tankdamere.

Ghost and Exhaust are all I use on Tryndamere. With this build the focus fire is not as life threatening seeing as you have that additional health from the Warmog's Armor, but Cleanse is acceptable. Never run Flash on Tryndamere and Ignite is not fabulous either.

You will almost ALWAYS have an escape route. Take note of where you're fighting and learn of the walls you can spinning slash through.

Tryndamere is awesome in ranked.

Moreso because of the immediate reactions to the insta-lock Tryndamere.

But then you carry and they bow at your barbaric feet.

So how 'bout that viking skin? I like it.
