Welcome to this guide of Tryndamere. Before asking any questions in the comment section, I would like you to read my explanation first.
Tryndamere is a great char if you know how to play him correctly. He can carry a team and deal a lot of damage to the opponents. In the following guide I will give you an idea about Tryndamere and how you should play him in normal AND ranked games.
Enjoy =)

There are those who choose not to live in one of the great city-states of Valoran. Instead, they live in remote locales, often as part of a nomad or barbarian tribe. While perils abound in these untamed lands, there is also great freedom in being removed from the politics of Valoran. Tryndamere was born a member of one of these barbarian tribes in northern Valoran. Even as a young boy, it was obvious that he would grow in martial prowess to become one of his clan's greatest warriors. However, as his clan moved south between the Howling Marsh and the Ironspike Mountains, they came across strangers in black garb, brandishing symbols of a beast's skull. Despite Tryndamere's pleas, his elder went out to speak with the strangers; they cut him down mercilessly. From there, they began to slaughter every man, woman, and child in the clan. Tryndamere, the sole survivor, hid under the bodies of his dead parents. Upon their bloodied corpses, he swore eternal vengeance on those who took his people from him - the assassins of Noxus.

To train himself, Tryndamere voluntarily served under all the great chieftains of the barbarian tribes, learning the ways of the barbarian warrior. Not only did this make him the man he needed to become in order to exact his revenge, it has also garnered him friends and allies among the most powerful barbarian leaders of Valoran. This recently allowed him to unite the barbarians into a single, powerful force - all under his command. Now he has joined the League of Legends to earn enough influence to find a permanent home for his people... and to slake his rage on the champions of his hated foes.

''The next true power will come from the far north, and it will involve Tryndamere - one way or another.'' -Graccus Mightstone, League Senior Political Scholar.

Pros

-Great damage output
-Escape ability
-Good chaser
-Can survive with no health
-Can carry a whole team

Cons

-Squishy for a top laner
-Depends on farm but is meelee
-Hard to play (no joke)

For runes I take Greater mark of desolation(x9), Greater Seal of Armor(x9), Greater Glyph of Magic Resist(x9), Greater Quintessence of Attack Damage(x3).
Why? The marks of desolation are a must-have for AD-based carries to be able to poke the opponent and have Armor Penetration which is important in late game as well. The seals of Resilience are important for your early game. As you are not that tanky with Tryndamere, you want to give yourself a little boost to be on the same level as your opponent and not be poked off easily. The Glyphs of Warding have the same function. Now the Quintessences of Strength give you 7 Attack Damage which is a huge advantage with Tryndamere.
You can also replace them with Greater Quintessence of desolation just as you like. I prefer the Attack Damage.
Recommended:
Greater mark of desolation x9

x3

For masteries I go 21/1/8 skilling Summoner's Resolve for improved heal and Summoner's Wrath for the extra AP and AD on ignite use. I skill 8 on the utility tree to reduce the death time and the time for recall, which gives me more time advantage against my top lane opponent. As Tryndamere is an AD-based damage char, you want to skill 21 on the offense tree.

Why this combo you ask? Heal is VERY important as you are squishy on top lane and need an extra heal to be more competitive. Ignite can decide an early fight 1v1 on top lane and is the best choice in my opinion. The only spell that you can replace is ignite. Heal is not discussable!

Possible Summoner Spells:
Cleanse is a good choice for Tryn when he gets focused and draws the cc.
Even though I think that Tryn doesnt need it, it can still save your life.
Ghost is an escape skill as well and could help you to pick up a kill early when chasing.
If he underestimates you just exhaust him and pick up the kill.
It could be a factor to return to the lane quickly or help out somewhere else.

NOGO Summoner Spells:
No... just no..... dont even think about it!
This is actually very useful for chars with no mana.
Not a dominion guide.
Hmm not a good spell...too high cooldown plus you wont die if you follow this guide ;)
You are not a jungler.
You kiddin me?
Your supporter will take it.

Tryndamere gains Fury for each attack, critical strike, and killing blow he makes. Fury passively increases his critical strike chance and can be consumed with his Bloodlust spell.
This is Tryndameres passive. You should try to keep the fury up as long as possible before you use your Q because it gives you critical strike chance and by that a lot more poking ability.

Passive: Tryndamere thirsts for blood, gaining 5/10/15/20/25 Attack Damage plus 0.15/0.2/0.25/0.3/0.35 per 1% Health missing.

Active: Tryndamere consumes his Fury, restoring 30/40/50/60/70 (+1.5) Health, plus 0.5/0.95/1.4/1.85/2.3 Health per Fury consumed.
Good skill to heal yourself, make sure you use it wisely and keep the critical strike chance in mind.

Decreases surrounding champions' Attack Damage by 20/35/50/65/80 for 4 seconds, and enemies with their backs turned also have their Movement Speed reduced by 30/37.5/45/52.5/60%.
This skill is better than it looks like. It is kind of like Exhaust and works very well for chasing and beating someone 1v1.

Tryndamere spins through his enemies, dealing 70/100/130/160/190 (+ ) (+1) physical damage to enemies in his path.

Spinning Slash's cooldown is reduced by 2 seconds whenever Tryndamere critically strikes.
A really nice skill to deal damage, poke and chase very well. Cooldown is around 2 seconds late game, as you will crit all the time.

Tryndamere becomes completely immune to death for 5 seconds, refusing to be reduced below 1 Health and instantly gaining 50/75/100 Fury.
We all know this ult and it is great for surviving or diving. It is very important to be able to use it correctly. But later to that.

You can see the skill sequence above. You priority is:
Undying Rage> Bloodlust> Spinning Slash> Mocking Shout
Of course your ultimate is your first priority. Maxing out Bloodlust at lvl 9 will give you a significant advantage on top lane being able to keep yourself in the green area if necessary.
Spinning slash is some extra damage and should be maxed at 13. Pick a point in mocking shout at lvl 4 and max it last!

The items might seem a bit odd, but I'll explain now.

You want to start with Boots and 3 Health Potion. Tryndamere has enough Attack damage and armor, so you wont start with a Cloth Armor or Doran's Blade or sth.

Try to stay on lane as long as possible and get Wriggle's Lantern quickly. Ward the river to see incoming ganks.

For boots....you have the choice. If you want to be more tanky go with Mercury's Treads, feel like you want to kill more quickly, get Berserker's Greaves.

To increase your crit and attack speed, buy Zeal and lead it straight into a Phage to make yourself a little more tanky. Frozen Mallet is your second core item which you should lead in Atma's Impaler. This increases your chasing ability and the slow stacks with your mocking shout. Atma's rounds it up with a decent damage and crit boost.

Lead the Zeal into a Phantom Dancer and round your build up, with 2 decent damage items like Bloodthirster (sell Wriggles for it) and Infinity Edge.

CORE BUILD

Optional/Situational items

I dont recommend this, but it is very useful against teams that build on health only.
This is a great item for Tryn and my biggest recommendation as it is just superior with your ultimate on.
Works well with Frozen Mallet and is also one of my recommendations.
If you die often even with your ult, take it with you.
Very useful magic resistent item.

Early Game

From the first second on the lane on, constantly poke your opponent top to give you an advantage in exp and farming (Care not to push too far as you are all alone and their jungler could come).
Dont shy away from a 1v1 face-up. Keep in mind that you have your Bloodlust and Heal as well as Ignite! As soon as you picked up a kill you have free farm, so decide wisely and read your enemy (See the list of champs below to see who you should fight and who not). Keep the Bloodlust up to have more crit chance and be able to poke better.

Mid Game

Here is where you should be ganking other lanes and building tanky items ( Frozen Mallet)
Try to get feed on other lanes and get more Attack Damage. As you are Tryndamere you can walk alone but you should not go roaming in enemy jungle with no map control. Start pushing towers away and keep your lane opponent at bay.

Late Game

You will have to do the damage. Let someone else initiate and go in to deal "Tons of damage" focus the squishys and take out the tanks after. Just be Tryndamere and take everything out that is in sight. If necessary, buy Elixir of Agility, Elixir of Brilliance and Elixir of Fortitude and ward the map.

Top Laners you do not want to face up against

Nidalee AD top is deadly for Tryn. She can heal herself and Tryn cant poke her that well.
Fiora has good damage and can parry attacks.
Riven is one of the best top laners in the game and way better than Tryn.
Better nerf Irelia.
The most annyoing top laner will annoy Tryn as well.
He will crush Tryn.

Easy Top Laners

his true damage won't help him much as Tryn will crush him early on.
Croc has nothing to say.


It is pretty much equal on other top laners but when you are skilled you will be able to outplay them.

How do I use the skills best?

Tryn is really hard to play in regard of the timing that the skills have to be triggered.
Tryndameres worst enemies are:

When you are ignited, do not trigger Bloodlust right away because ignite reduces your healing. Also try to spare your Heal. Use Bloodlust before you use Heal, that point should be clear enough.

When should I activate ultimate?

You should activate it early enough if you are in a situation where you are alone against several guys. If you are 1v1 you want to use your Bloodlust before Undying Rage.
