Note: Strength and numbers alone do not define the true might of a Knight. These are but measures of the flesh, standard markers of their physical form when put into numbers. Yet many things lie beyond such measures: experience in battle, the weight of their weapon, the quality of their armor, the flow of their fighting style, all these and more shape their true power.
As for Lumberling's daily training, do not expect skill points to come with every passing day. It is like the steady swing of a hammer at the forge, progress is not always seen, but each strike still shapes the blade.
