Swim action suppresses the “tail swing” and creates a natural feeling mainly based on extremely weak rolling . At the time of contact with the water stream, an exquisite irregular swim occurs, causing a bite opportunity semi-automatically. The restoration from the irregular swim is set to the highest level, so there is no sense of discomfort. The failure of actions is completely eliminated . The usage is basically retrieve only.
