First of all Mr Dinger is a fearsome champ with insanely overpowered skills and, well yeah everything! If played correctly will the amount of pentakills be overwhelming and you will get a guaranteed challenger spot.

Items are for little p*ssys, the dinger doesnt need 'em. Just rock some non-existing items and you're fine!

Riot have announced several times that dinger is way too op for the game. They have tried several times to remove him, but in vain. The evil genius took over the system and prevented riot from removing him from the game, permanently! So if you now by any chance would dare to play the god of gods, the evil genius - the fearsome dinger, thou shan't buy any items for the sake of your opponents. As Dinger get's insta pentas every third minute isn't any items necessary for him, it's simply humiliating for your oppponents if you get any stronger... so be human and dare to resist the urge of buying your capitalist-pig!
