Is "The Maker's Own Power" Locked Behind Killing the Eyeless?

[Cyrus_Blackfeather]

Hey guys, 

 

So I'm curious about the "Maker's Own Power" belt item that you get for completing a particular bounty. The flavor text seems to suggest that it requires killing the Eyeless and not allowing them to restore Abydon. Is this the case, or can you get it on a save where you allow them to restore him?

I received the belt and I tempered and restored Abydon.

I've played with a bunch of custom and premade backgrounds, surely with varying decisions with regards to the Eyeless, and I can't recall that belt not dropping.
