This build is designed to maximize your team fight potential. Once you use this build you will be too tanky to die and deal too much much damage to be ignored and have too much crowd control to be ignored.

These runes are used to give u maximum tankyness as well as magic pen for damage output.

These masteries will also assist in being tanky.

This build is designed to give you so much penetration that your spells will deal near true damage to every squishy character, as well as the potential to seriously injure tanks. You will also be able to disrupt fights while being tankys and deal serious aoe dot.

This spells order will help greatly for when your jungler comes to gank or for when you get ganked. Maxing ethreal chains really helps to secure kills especially when Mimiced. Maxing your dash second is great because you will be able to deal tons of aoe damage in team fights. It is also great for escaping and chasing down enemies.

Heal grants your entire team sustain and exhaust is great utility.
