Shyvanas lack of CC has made her spit upon by most competitive gamers. But her damage and ability to tank are tremendous.

Armor Pen on Reds is kind of a waste as her damage is both physical and magical. I use physical damage to boost her early game, which is her weak point.

Seals are very standard. Nice resistances early on.

Glyphs are per level and not flat, since i don't play shyvana at mid lane.

I use flat movement speed quintessences because shyvanas greatest weakness is being kited. She has no cc to stop foes.
