"Now, First Order Knight Training is a bit special compared to what you did before. Previously, you learned how to use the three basic weapons of a Knight in a fight, but now you will learn to maintain them." Misery explained as he tossed an empty bottle at Kiran, who was struggling to get up after having stupidly tried to pass his Buddha Lineage Energy through the pathways that his Merlin Lineage Energy passed through. 

Basically, you can think of it as Kiran trying to pass heat Energy (Buddha bloodline) through a circuit (pathways for Knight activation) instead of electric Energy (Merlin bloodline). 

After being struck by another of Misery's empty bottles, he finally got back up and was able to listen to his Uncle properly. 

"Back at home, we called this weapon maintenance section 'git gud'." Misery reminisced casually. 

"What is the stupidest thing a Knight can do?" He suddenly asked cryptically.
