I think this was a very cute and quite helpful little spellbook! I am glad that the cute-ness didn't force any sacrifice on quality information. I think the spells listed here were very well thought out and even they were cute too.
I think all spellwork is open to interpretation and I think there is a good amount of wiggle rooms in these "recipes".
I do wish that there were alternative options for herbs and crystal for people who might not have access to certain things but other than that I did quite enjoy it and will be using it in the future.
