Hello, it works only by defeating the Dark knight Boss battle after repairing the forge.

hmm well I’ve repaired the forge and battled the dark knight via the library and didn’t get the card, maybe I need to find a dark knight out in the world instead?
ETA oh maybe you mean there’s a battle with the dark knight that happens automatically after repairing the forge? Sorry, it’s been a while since I played that part. I probably lost haha
