Lukas and Oak fought for hours, with Oak constantly changing how he fought with each consecutive match. He seemed skilled at adapting to his surroundings but a master of no one weapon or style. The only underlying continuity was the same dagger he held close to the bonds of his Frequency.
He seemed experienced in using the small blade in a variety of ways. From precise parrying to close-quarters cuts. Although it was mostly meant as a surprise tool as opposed to a main weapon of sorts.
But when their sparring came to an end and the day with it, Oak said something small.
"...I haven't felt this exhausted since I was a kid."
