Where to get an Adamantite?

[Skidz]

I would like to upgrade Lighting's Axis blade, but before I buy the adamantite from R&D, I'm wondering if I'll come across one before I finish the game. Anyone know where to find/farm one?

Xiao Long Gui, IIRC.

Xiao Long Gui Only drop Gold nuggets as the norm and Dark Matter as the rare.

I think you might get one (MAYBE two) from normal stuff, maybe a mission reward, but after that I believe the only place to get them is the store.

Sadly, no mission gives adamantite as far as I know

[Correction]

To clear up any confusion, Adamantite can ONLY be bought. Nothing drops it, it's not in any treasure chests, and it's never the reward for any mission.

Thanks Correction.
