For two hours after recovering from his injuries armed with a wooden shield and one-handed ax provided by Gwen, Aito fought a steel dullahan equipped with a wooden greatsword—taking a break every twenty or so minutes.
Also, he wasn't allowed to use Durability. Nor was he allowed to swap for new weapons until Gwen said so, even if they were broken.
Moreover, the empty armor had a seemingly bottomless reserve of stamina, allowing it to strike consecutively without interruption.
'What a pain in the ass,' Aito thought, blocking what felt like the thousandth strike. The dullahan's moves left little to no openings. At least it seemed that way to him. However, if there were no openings, he could create one, something he had already done many times.
Fun fact:
Glima is a "martial art" supposed to have been invented by Vikings. Supposedly, it used to be passed down from father to son, secretly. It is said that it had helped the Vikings forge their reputation as strong warriors.
