This is a guide who helps you to build a killing machine from hell, Shyvana!

Other options:

Crit damage

Crit chance

Attack damage

Attack speed

Armor pen.

Cooldown red.

The ONLY thing you can do is to switch your Last Whisper to Guinsoo's Rageblade.

Joking, you can switch any item you want, but you should know that if you build your Shyvana like this your team will win!

Good items:
Wriggle's Lantern
Nashor's Tooth
Madred's Bloodrazor

Deal damage to the whole minionwave with Burnout then last hit with Twin Bite. Nuff' said, easy mod!

Good luck, and i know you will have fun!

When building the masteries i decided the best options would be to optimize damage whilst keeping a little bit of sustain on the side, obviously going for the excaust mastery since thats very helpful with its resistance reduction, which completely supports what this whole build is based on, What i realised with shyvana is that ad ranged, seem to pow her down like shes nothing, but shes a dragon this cant happen!, so i thought what would be best for this... dodge... i felt the best attribute of shyvana is that she has loads of movement speed, and attack speed, giving her nimbleness was great for chasing or fleeing purposing, for example, on a lane if chasing someone the minions will be pewpewing you as youll most likely damage them with burnout, if this is happening youll dodge with ninja tabi, if you dodge you get that extra 10% movement speed which will hopefully secure your kill. You could possibly go into utility for cooldown reduction or maybe even the flash improvement but i felt that shyvana gets enough cooldown reduction on her abilties and even duration increased through her passive, so this was not nessesary. but with the offensive and defensive mastery build i gain attack speed, attack crit, for her q and w then i also get magic pen aswell for her e and ultimate, this overall increases the bonuses of all shyvana's abilities, then i went for defense as the primary aim of this build is to hit high damage whilst keeping sustain and lane durability, also possible tank/offtank for the team.
