I made this build for all the shyvana players who don't know what to buy, becous with the right items she owns like a dragon.

pros:great early game
great burst damage.
nice skins.
and who don't wants to be a dragon. =)
cons:when not feeded not much damage
when misplaced spells you're death

I choose for defence runes becous shyvana needs to be durable while she gets in a fight, especialy in early game.

In my items i tanky dps, for the same reason of the runes.
you can change some items like wit's end when there is no mage in the enemy team.
You can also change infinity edge into atma's to be more tanky.

I max my second spell first becous it can clear out minions easy and deals much damage on champs to

i use flash and exhoust
flash is just the best summonerspell
and exhoust becous shyvana has no slow or stun

For farmid just use your second spell, and last hit the minions when you can.
If you have it dificul to farm against 2 ranged champs try to hit them with your third spell so they go a bit back, and when they don't go back you can harras then a bit with your spells and basic atacks
