In the six Arrow heads, there is one Arrow which is different than the others. 5 have holes while the 6th has a bug thing attached instead.

Incidentally that Arrow was the one giving people Requiem Stands. Could it be that this 6th Arrow could be a superior version which can unlock further power for Stands? Could explain the utter lack of Requiem Stands in other parts.
