Learning skills for Luke was a completely different experience compared to learning skills for Leo.
While Leo had to understand the basics of mana and mana manipulation to cast spells, the type of spells taught to Luke had a completely different casting process.
The spells used by a knight leaned more towards physical reinforcement rather than manipulating the surroundings and hence its casting process was much different as well.
While Leo had to cycle mana in his body along a particular path to create resonance with his surroundings, Luke only had to imagine sending mana to his body part that he wished to reinforce.
Unlike Leo who first drew mana internally and then influenced his surroundings, Luke first drew mana from the surroundings into his body and then guided it towards the body part or weapon he wished to reinforce.
