Note - this guide is still under construction, so things will be added up and changed as my understanding of Shyvana grows.

This is just her build, the full guide will come a bit later. I just want to know if you guys find this build eligible. So comments and feedback are highly welcome.

Explanation of this build:

I'm trying to build her as a tanky ad, with an amazing amount of burst and sustainability throughout the whole game. This build will give her everything that she needs, health, atk damage, a bit of AP, and atk speed.

This build aims to get you into the fight head on and still survive the whole battle with one or more kills, maybe even assists. With this build you'll be able to play multiple roles in team fights. Examples, even though that you're not a tank, you'll still be able to absorb a lot of damage and survive with around half health, also, with your tankiness people can misjudge your damage as they think that you're just tanking, and this build really does punish those kind of players. Overall, you're tanky, beefy even, have a pro ultimate that can send you straight into your opponent's face and deal a TON of damage. And no, I'm not exaggerating.

Hope you guys try it out :)

Starting off with boots and three pots is, in my opinion, the best way to start with her. Later on, you can either get berserker's greaves if you feel up to the challenge or Mercury treads if the other team has heavy cc.

But if you think that you're going to be losing a lot of health in lane, choose Regrowth pendant as your first item, and a potion. This will sustain you in lane for quite a long time, especially if you chose to solo top. This item then may be sold later on or you could build it into a warmogs.

Trinity Force is the first main item you will get. It is the core item of this build as it is amazingly amazing on her. Once you get this item, your abilities and your atk will deal a ton more damage, not to mention that you have a little bit of extra health to help you sustain more in battles.

Frozen mallet is also another core item. The extra health is a must for Shyvana as when it gets to mid game, you will have to actually 'get in there' a lot, meaning that in team fights you will be one of the few to be doing the damage from the frontlines. The slow also helps you to stick with enemies so you can do the extra damage with burnout and have time to land a few more atks (including your Q - twin bite) on them.

Warmog's Armor gives a huge amount of health, exactly what you need in team fights, you can get this instead of frozen mallet if you think you're doing enough damage.

Wit's End is the last core item for her. First off, the atk spd you get from it is amazing, giving you the extra fury you need to sustain your dragon form or to get into it faster. Also when late game comes, you'll want to do sustain damage instead of momentary bursts.

Rageblade is a nice item as it gives more atk spd for you. And the extra AD and AP just adds to your power. Amazing item for late game.

Gunblade is just here as a finishing item - Usually, you'll never get to this point, unless your in a super epic long game. This item is very situational and it can easily be replaced by another item.

Atma's is another optional item that you can get. With the amount of health that you have this item won't disappoint.

An important item for all AD melee, especially when the other team is stacking on armor. Consider this item when you see your opponent's team is heavy on armor.

Shyvana is, in my general opinion, one of the best tanky AD's out there - She can get quite beefy and still deal tones of damage if the right items are chosen. With this build, I guarantee you that kills will come easily to you.

Pros

-Abilities just go well with each other
-Her Q (Twin Bite) does a tone of damage throughout all phases (Early, Mid, Late)
-Dragon's descent is a great tool for initiating ganks, good for disrupting a team's formation in team battles, great escaping and chasing ability, and it comes back up in almost no time if you keep farming.
-Has two great escaping and chasing abilities (Burnout and Dragon's Decent)
-A very fun champion to play

Cons

-Easily harassed early game if paired with another melee champ.
-Ultimate (Dragon's descent) can be a used wrongly, especially if used to push opponents away from your team when ganking.
-Aimed most of the times in teamfights
-People can tell if you have your ultimate or not because your fury bar indicates it.

Why did i pick these runes?

greater mark of desolationMark of Desolation is essential to all AD champs, so why not on her?

Seal of Alacrity - Gives the extra atk speed for your early game. Optional, but helpful.

Glyph of Focus is just amazing on her throughout the whole game. Less cooldown time means more spamming, right?

Quintessence of Potency is highly optional. The only reason I chose this is because of early game AP boost. This can be easily replaced by anything else.

Quintessence of Fortitude is a good choice for people who find it hard to sustain in lane early game.

My masteries are quite simple - It is based of my Irelia masteries that focuses more on damage than utility and defence. Really, I suggest people to skip the utility tree. It's not good on her as it is on other champions.

Simple 21-9-0

(Active): Shyvana next autoattack will strike twice in one swift movement. The second attack will deal physical damage equal to a percentage of her total attack damage. Both attacks will trigger on-hit effects and Fury of the Dragonborn effects.

Dragon Form: Twin Bite will damage all units in front of Shyvana when she uses her next autottack instead of just her target. Each unit hit will be dealt on-hit effects and grant Fury twice.

Fury of the Dragonborn: Each auto attack reduces the cooldown by 0.5 seconds. This doesn't work on structures.

Twin bite is probably her most damage ability and put a point in this second and max it out first if you're the type of guy who likes to get in there and burst them in the face for maximum damage, though I like to evenly max it out with burnout as I found that both do incredible damage when combined. Also, this ability is quite spammable because of Shyvana's passive.

(Active): During the next 3 seconds, Shyvana will deal magic damage each second to nearby enemies and her movement speed will be greatly increased. Shyvana's movement speed bonus itself will be reduced multiplicatively by 15% for every second that passes.

Dragon Form: Shyvana now scorches the earth where she walks, leaving a trail of fire for 5 seconds that will continually deal magic damage to enemies that pass over it.
Cooldown: 12 seconds

Fury of the Dragonborn: Each auto attack extends the duration of Burnout by 1 second to a maximum of 6 extra seconds. This works on structures.

I put a point in this ability first for bonus movement speed and constant early game damage. A good ability to farm with. I max this out evenly with twin bite.

(Active): Shyvana unleashes a fireball forward in a line that will hit the first enemy it hits, dealing magic damage to it and debuffing them by reducing their armor by 15% for 4 seconds.

Dragon Form:Flame Breath engulfs all units in a cone in front of Shyvana.

Fury of the Dragonborn: Each autoattack that hits debuffed targets will deal 15% of the ability's damage as extra magic damage.

I put one point in this ability at lvl 3 and leave it till all my other abilities are maxed. I find that this ability does the least amount of damage and all you need it for is because of the debuff it does.

Passive): Shyvana reinforces her scales, increasing her armor and magic resistance. These defensive bonuses are doubled while in Dragon Form.

(Active):Shyvana transforms into a dragon and dashes to a target location. Enemies along her path take magic damage and are pushed toward her target location.
This ability has no cooldown but to use it, Shyvana needs 100 Fury. Shyvana generates 1 Fury every 1.5 seconds while on normal form. While in Dragon Form, she will lose 6 fury every second and once the Fury bar is empty she will return to her normal state.

Fury of the Dragonborn: Each of her autottacks will generate 2 Fury. This allow for Shyvana to prolong the duration of Dragon Form by attacking

Best ult in the game, hands down. This is probably one of the best abilities to use in team fights. One swoop in with this ability, your enemies will be running around disorientated. This ability will crush you're opponent's formation, it will stuff up any channeling champions(Katarina, Nunu, Karthus, etc), and it will definitely change the battle to you're team's favor. Not to mention that it is the best gank initiator.

Her abilities are quite straight forward, twin bite is her main damage dealer, burnout is her damage over time ability that also gives her a massive speed boost, and her E ability is there to deal the extra damage. As explained above, her ult is very useful in team fights, if used properly, then the battle is yours to win.

There is really no way to explain on how to use her ability other than start of with your W ability (burnout) as the extra damage helps. If they try to fight you back, shoot your E ability for the debuff and quickly use your Q, this will deal tons of damage. And remember, spam your W and your Q as much as possible, they are your two main abilities in fights.

Laning isn't as hard as people make it to be with Shyvana. She has good harassing abilities, good farming abilities, and a sick ganking ability (Dragon's descent). But of course, one downside of Shyvana is that she is melee, and melee in duo lane tends to get harassed a lot. I know this from experience.

This is why I recommend new players to start of with boots of speed and three potions or regrowth pendant if you know how to play safe. This will give you the extra speed if escaping from giving first blood, and enough potions to sustain you in lane till at least level 6. But this isn't enough most of the time - what if you run out of potions? What if your extra speed is still not good enough? Well, that's why you don't pick mid and instead go to a duo lane where you have a partner to look after your back.

Your laning partner is probably the biggest factor in your early game. The way your partner plays will determine your early game to mid game results. My recommendation of a partner is someone that is ranged, or at least someone with a ranged harass ability. Any type of cc would also work, preferably a stun or taunt.

One example would be Caitlyn - If there's already someone mid and a Caitlyn is free to go to a duo lane, then I suggest you go with her. With her range and powerful harass, you'll be able to farm and zone your opponents out throughout your whole laning phase.

So remember guys,either pick someone ranged or with a ranged harass, or even a strong cc for a partner. This will aid your laning phase by heaps.

(Since i'm getting down voted for this part of the guide, let me explain, this part of the guide is to help newer players who have an interest in playing Shyvana without playing in a solo lane or jungling. Not all games are like ranked, and if you are playing ranked, then you should have enough experience on what's right and what's wrong to do.

Early Game
Early game is quite simple for Shyvana, focus on farming until around lvl 3. When you reach that lvl you can think about harassing a bit with burnout and twin bite. DO NOT over commit with this, unless you're doing a TON of damage and they're around one bar of health. Remember, you're trying to harass them, zone them out, stop them from farming. Never go for a kill unless you're sure you'll deal the right amount of damage and have an escape plan.

But still, main focus of Shyvana in this phase is to farm, so don't over do it with your harassment. And once you hit around 1200 gold, teleport back and finish off your boots and get a ruby crystal

Note!!! that when you're farming in early game, move around a bit, don't stay in one spot for too long. By doing this you're less likely to be hit by skill shot harassment, and it'll make your opponents wary of you as they don't know what you're about to do next. REMEMBER - keep moving around and never stop, even when farming! This is why you have your W ability - Run into the minion waves so your W does its damage to them, and last hit the weak ones, then run back so you're behind your own minion wave. PLEASE remember this guys. Shyvana is very vulnerable in lane if not played right, so try to not stay still.
Mid Game

Mid game starts when you hit lvl 6. If you haven't gone back yet, then teleport back and buy a ruby crystal and finish of your boots to berserker's greaves if you haven't yet. If you've already got them earlier, then get your phage and start roaming.

By roaming, I meant look at the map and see which lanes needed a gank. If you think that they're doing alright, head back to your lane and try to finish off the tower there. But if you see a lane in need of help, go there and help. Remember, your ultimate is one of the best ganking abilities in game.

Remember to look at your gold. Every time you reach one thousand gold, then head back and purchase your sheen if you haven't or finish off your trinity force. By getting this item, expect that you'll be doing a ton more damage and will be able to survive for quite a long time in team fights.

NOTE!!!! Whenever there's no team fight happening, you're job is to farm as much as you can and push. This means that you push lanes that needs to be pushed, without over extending too much of course, and clear out the jungle. Remember, map awareness is the key to this phase of the game.

Late Game

Late game starts when you've finished building your Wit's end, meaning you probably have all your core items. Usually for me, I never get to this point very often as my games usually finish when i get my trinity force (yes, trinity force is that big of a boost for Shyvana).

But if you do reach this phase, then start looking at your opponents team and see what they have, meaning their items. If you've done well in your early and mid game, then your opponent shouldn't have too much strong items. If they do, consider getting tankier and buy a Warmog's followed by Atma's. But if you think you need more damage and have enough survival then consider getting a Guinsoo followed by hextech gunblade. If you see them stacking armor, then consider getting a Black Cleaver.

You're role in the major late game team fights is to disrupt the enemy team with your ultimate (dragon's descent). NEVER engage with this ability, always let your tank do it. Only use Dragon's descent when your whole team has engaged. By doing this, you'll be able to disrupt your enemy when it matters most. Also, try to use your ultimate ability over walls as this will get your enemies on their toes. A successful ult means a successful battle, so try to use it properly as every battle in late game can decide if you win or not.

I've included another build in this guide, the first one, which is automatically featured is a more 'powered' base build, meaning a bit more damage over survival. The second build is the opposite of the first, meaning more survival, a bit less burst

Both builds are viable for games and they are as powerful as each other.

Also, if you want to have a game with me on Lo or just want to see my match history, my in name game is TheNoobTalk in the North American server.
