When Minos' group came across those artifacts that were freely placed in the area for anyone to pick up, they quickly spread out.
There wasn't just that big, high-level grade-4 axe. Several other low- and medium-level grade-4 artifacts were scattered around the area.
For some equipment, it was not enough to have the appropriate level to wield it.
Above low-level grade-3 artifacts, all kinds of items would have unique characteristics, such as innate powers, that their users could activate by infusing their powers into these weapons.
But could a cultivator with an affinity for ice, for example, activate the flame ability of an axe?
Not likely!
To master these weapons and use them, one would not only have the strength to bear the weight of the artifact but also have to have an affinity for it.
