The drop rate of this Blood Ancestor is truly delightful. Just the Artifacts alone amounted to five pieces in one breath, although two of them should be spoils from his previous fights, right?
But what on earth is that Eagle Feather Cloak?
Although such a cloak seems to have appeared in the original work, it was made by Shu Sheng for Di Yun after the death of the Blood Ancestor.
Why is this thing appearing on the Blood Ancestor now?
Could it be to provide players with a legitimate way to acquire this piece of equipment?
And the one made by Shu Sheng herself was exclusive to Di Yun, just like the snake blood that Guo Jing drank, which players had no chance to get?
This explanation seems plausible, but it's not the point.
The point is that this thing is already in hand, it's pointless to fret about how it came. The real issue is distribution.
