All things considered, upon picking up the sword, Motan immediately drew two conclusions.
Firstly, Ruvie intended to give Ya Ya [Atr's Mark], an immensely powerful weapon. Not only are the equipment requirements low, but this sword is immune to ice, fire, and lightning properties. This means, as long as you use this sword to attack these three types of magic directly, the user will not sustain any injuries. What is most significant though... the sword never wears out, in simpler terms, its durability has no upper limit! This attribute hardly ever appears in equipment that are only of unique crafted quality, but here it is!
Secondly, Motan remembered quite clearly that Ruvie had said the sword was made decades ago, yet the notes on it suggest it was actually made 387 years ago!
