I'm starting to suspect they're gonna be special giveaways of some sort. Together, I'm pretty sure this community has dug up every single weapon in the code of the game. Even if they're boss-only, Abassa/Andaba is always crowded with looters trying their luck at Drench and Drizzle and the best we've got are reports of old legends. Of course, there are some rare items such as the Gorilla Broadsword which aren't found often because the enemies that drop them are under-looted, so they could be well-ensconced in some method no one ever cares to try.
