Shyvana is a multipurpose champion, she can jungle, solo top or lane with a partner. She has got as stylish as powerful abilities, and she can transform herself to an powerful dragon, which will increase her abilities and her survivability...

A spell: Double bite
The next attack will hit twice Shyvana. The two attacks apply effects and the impact of the dragon.
Shape of a dragon: double bite wounds all units to Shyvana.

Z spell: Combustion
Shyvana causes magic damage per second to nearby enemies and moves more quickly for 3 seconds. The bonus movement speed gradually decreases.
Shape of a dragon: Combustion burns the ground and enemies that are above continue to suffer damage.

E spell: Breath of fire
Shyvana launches a fireball that deals magic damage and melted the armor of the target for 4 seconds.
Shape of a dragon: Breath of fire burns all units in a cone in front Shyvana.

R spell: Flight of the Dragon (final)
Active: Shyvana turns into a dragon and flew to the targeted location. The enemies along the way suffer damage and are pushed to the target area.
Passive: Shyvana hardens its scales, increasing their armor and magic resistance. Defensive bonuses are doubled in the shape of a dragon.

The dragon (passive)
The melee attacks of Shyvana improve their skills.
Double bite - Reduces the cooldown of 0.5 sec.
Combustion - Increases the duration of 1 sec to a maximum of 6 sec.
Flame Breath - Inflicts 20% damage to targets within the jurisdiction affected by the spell.
Flight of the Dragon - 2 pts attacks generate Fury and the Fury Shyvana gaining steadily in his human form.

In Red, I take some attack speed marks, because improving ATK speed, you will improve her abilities, so her efficacity in battle.

In Yellow, I take HP/lv seals, Shyvana can up levels easy, because she can handle a lane alone, so I think it's better to have these seals. Armor seals flat is also a viable choice.

In Blue, I take ATK speed also, same reason as marks, but You can take Magic resist flat is you prefer.

In quintessences, I take HP regen, because they help her to sustain more in early, which is important. HP flat quints are good too.

I take Flash and Exhaust, Flash is useful for everything: gank, escape, place out your R, and more. It's a must.

Exhaust: Same as Flash, take it because you don't have any CC (slow, snare, root, stun...)

Others Spells:

-Teleport: A useful spell for gank, defend a lane, arrive to a team fight. Change with Exhaust.
-Ghost: same as flash but you will not need mostly because your Z replaces it, but you can take to have an epic mouvement speed.
-Smite: Only for Jungling... Change with Exhaust.

I take a 8/22/0 masteries, for max ATK speed and her sustain potency in early. But you can take an Other Combination...

I take Z at lv 1 for farm well, and at lv 3 I have all the basic spells, to harrass easier. Then Max Z, because of the MS bonus, then max the A for burst damage and finally up the E, E is only for harass in this guide. Up the R spell when it is possible.

I take an Doran Shield as first Item, for sustain easy a lane until lv 6.
Then take your Mobility boots, because have a lot of MS on her synergies with her Z. To gank, and place your R, etc...
Take your Sheen for Boost your A, a zeal for purchase Trinity later.
Then take Wit's End for ATK speed, Magic Resist and his DoT, shyvana NEEDS IT!
Take out a sunfire cape, for survivability and the Aura which is synergies with Z
Take out an Phantom Dancer because of the MS and ATK Speed and Crit %tage synergies with A spell and finally the Infinity Edge to boost your A and your AD, synergies with Phantom Dancer.


The aim of this stuff is to boost your spells A and Z, as you can see those items synergize a lot with Shyvana, she will be rapid, powerful, and she can sustain in a whole team fight.

Hum... Actually I don't like the idea (even if it is her main role) of bruiser on Shyvana, but I can only do some suggestions:

-Take Atmog combination.

-Trinity force is a must on every Bruiser on the game (Garen, Nasus...)

-Force of Nature is always a nice Item, which is synergize with Warmog or Frozen Mallet.

-Randuin's Omen is an amazing item on her, due to the easyness of approaching ennemies. Randuin's active can do the change of an Team fight.

-Hum, you can see also others builds or guides, to see an offtank Shyvana, there is a lot of those builds. Besides, this is not the aim of this build.

I didn't try yet Shyvana jungling. But I know she is an Amazing jungling champion. She can do it quickly.

Pros:
- Good mobility with the Z and R spell.
- Good defensive stats with R's passive.
- Can AoE damage with the Dragon form.
- Good farming.
- Multipurpose Champion which can jungle rapidly and easily.
- Doesn't need much Damage stats to burst out an ennemy, even it is better.

Cons:
- R spell useless in a duel.
- Hard to gank when not at LV 6 or more.
- Lack of sustain potency, which is mitigated with Runes and Masteries.
- No CC, but it is compensated with her mobility.

Shyvana is finally a powerful assasin eventhough she is actually a bruiser, which can track an ennemy when she wants, and hard to kill, because of her mobility and survivability, even if she cannot stun, slow, snare etc...
