The first day in the Scrap Iron Hills yielded ten ordinary-level demons and a piece of 'Echo' attribute source metal.
Yan Luo is taking notes in his journal, and he has identified the type of source metal he acquired using the information stored in his eyepiece.
The source metal with the Echo attribute is very expensive, costing about one million to one and a half million more than his previous estimate of three million.
Engraving tools made from 'Echo' metal are best suited for use by engravers in the spellcaster class sequence. For example, after a single cast, echo metal will replay magic power, creating a secondary spell with 10% to 30% of the original spell's power.
Similarly, echo metal is also suitable for engravers in the shooting class sequence since these engravers generally attach magic power to bullets to counter the demons' deflection shields and enhance lethality.
All in all, it's an attribute with widely varied applications.
