Easy "Mad Fingers" Achievement
In the Lamia's village at the swamp, there is a bush that can be used as a punching machine. You must hit it at least 250 times. Because you only have once chance to start the punching event, save the game before starting it. Pressing [Space] or clicking the Left Mouse Button counts as a hit. Clicking the mouse and pressing [Space] both rapidly and at the same time is required to earn the achievement.
