This is my first guide. There is no provision but I want to show how I interpret Shyvana . Please commented and rated.

Pro´s
- nice lategame
- good farmer
- good escape
- heavy damage


Con´s
- in earlygame squischy

If you beginn with Boots of Speed you have no 100 life and no lifesteal but the 3 health poitions are better i think. If you dont want to start with Boots of Speed you can start with Doran's Blade.

Phantom Dancer and The Bloodthirster are your fisrt items. Phantom Dancer give's you nice attack speed and critical chance. Also you get movement speed which is nice to get away or to chase a target. The Bloodthirster in combination with good farm gives you massive attack dmg and lifesteal.

Frozen Mallet is a musthave for Shyvana because of the 700 Hp. If you leave it out you are to squishy. In combination with your skill Bournout it's impossible to get away from you.

Atma's Impaler is good because of it's passive which gives you many attack dmg because of Frozen Mallet and Banshee's Veil. Atma's Impaler and Banshee's Veil will also give you some basic resists. If you dont need Banshee's Veil you can change it with Trinity Force which gives you a nice dmg boost.

Start a fight with Flame Breath to reduce the armor. If a target try's to get away you can use Dragon's Decent or Bournout to get it. In Teamfight's use Dragon's Decent to deal AE dmg with all your spells.

There are those few dragons in Runeterra who have mastered the intense magical energies that course through their unique anatomies, evolving into an elusive Celestial Dragon. These powerful and enigmatic creatures spend most of their time hidden away from the lands of men. However, there are those who find themselves drawn to civilization and who take on human forms to immerse themselves in the world of humans. Occasionally, one finds itself drawn to the spirit of a human and they have relations. Sometimes, in the slimmest of odds, the union will bear fruit and that offspring will be one of the few half-dragons to have graced Runeterra. Shyvana is one such creature, born to a simple Demacian farm-girl and her Celestial Dragon father. Left to be raised by her mother, her oddities were something that couldn't be hidden from her community, though she was protected by her family. Once her family had perished in disaster, she was left alone for the first time - truly alone. Shyvana quickly became an outsider and it wasn't long before the community's fear began to put her in danger. Facing mortal danger at the business end of an angry mob, she was rescued by the traveling noble, Jarvan Lightshield. The noble was a man who strangely knew exactly what she was and took her under his wing. It wasn't long before she was offered a chance to use her natural skills in the service of Demacia, as Jarvan initiated her as one of the elite guard. Following Jarvan into the League of Legends was only natural.

Shyvana is a fierce warrior, with the blood of one of the most powerful magical predators in all creation flowing through her veins. Unlike some of her fellows, she is a subdued personality - somber, cool, and collected. However, when the moment strikes, her draconian heritage manifests and there are few that can stare her in the eyes and not feel the primal urge to flee.

''By the blood of my father, I will end you!''
- Shyvana
