You need the ronin. It must kill a Pekka first and then 3 crown the opponent on its own. Works with the quick play feature with a friend (QR code only)

Edit: the last hit on the kingtower has to be made by Ronin

He had me good. But for some reason he left the game because he thought he had already won or something. But i managed to make a last second play and went all in. Fireball saved my ass. That's why I always play to the bitter end.
