Hero's Sustained Attack I

It's easy to repel a single attack, but it’s almost impossible to defend against blows coming from all sides. Train your Hero in powerful attack combinations and they will inflict even greater damage on enemies! Upgrading this Knowledge increases the number of attacks in a series, which determines the bonus.
