The most magical thing is that this enormous source of power looks just like an ordinary rock.
I really want to crack one open and see what is inside.....Anyway, now I got 10 of them. Shouldn't be a problem right?

On your journeys you may have seen some similar mechanical runestone Guardians. However, the [<S>100768|Martial Protectors of the Relics] and [<S>100766|Martial Guards of the Relics] are somewhat different due to their greater speed and power. I think they must have an inner source of that abundant power driving them!
However, samples are more difficult to collect because they are so strong.....Anyway, I think for an adventurer like you, this is not so difficult.
