Luminate's Backplate's Auric Lodestone gather
almost same issue here, but I can only guess it’s the same problem I had with the “Machined Shield Backing” required for Machined Shield → Horlogicus / Glint’s Bastion.
Said issue?: RNG.
Took me over 100 Noxious Pods to get it.
As for the Auric Lodestone, I too have been looking to get it (haven’t completed Auric Weapons though).
Mined many, many ore nodes and no cigar.
I have noticed that the Auric Slivers you’re supposed to get from the ore nodes as well are an extremely rare drop (I think I’ve had one in about 100+ ore nodes).
Going by this, I can only assume that the Auric Lodestone is an even rarer drop, so going by my rates it’s likely a 1/200+ drop-rate.
You’re just getting unlucky with the RNG.
