Where to find blacksmith stones? (Elden Ring)

Mind_Flow
Yes, as usual: inspect locations, dungeons, knock out from enemies (they can definitely fall from Godric's soldiers and from green troglodytes from dungeons). Plus, a lot of blacksmith stones of different suits are scattered around the castle of the Storm Veil, only this castle is guarded by a stuffy devil-sorcerer with a stick, on which damage comes very badly, so it’s better to come to him at least with a gun +3, but even then he can drink blood , as in my case.

To begin with, you can shake the mine.
