The training regiment that Ben had planned for Leo after breakfast was even crazier compared to his training until then.
As if climbing mountains and killing squirrels wasn't enough, Ben wanted Leo to practice weapon arts between breakfast and lunch hours where he would personally instruct Leo on how to become proficient with weapons.
In the world of Terra Nova, weapon mastery was considered a separate department to skill moves and one could master as many weapons as they wished to, just like one could learn to speak multiple languages.
According to Ben, while an assassin needed to have a passable grip on every weapon, whether it be bow, spear or mace, they needed to be masters of the short sword and dagger.
