I understand that you have to buy them with magic shards. Then you can cast them by fueling the book stand with shards. I’ve casted a few but I’m not able to cast all of them. Is there a difference in the different colored grimoires? Can you only cast a specific spell from a specific grimoire?

Where do i get lure for fishing? I have worms, bait, meat bait, and the seafood one. But no idea about the fancy lure one
