A well thought-out set of tables to roll for or pick different quirks and traits to define a character or to create magical traditions for a setting. The aetheric magic variant rules at the end of the document seem well done, too. Looks great on a screen but printing in b&w makes it a bit murky but still totally usable. It would be nice to have a more printer-friendly version, though.

This is a book of "ideas" rather than a book of "things".

It's good for what it is. It's nice to have all of these ideas available in a single place. If you want to build a new campaign world, where magic "works differently", this would definitely be a launchpad.

But if you're playing with something fundamental like magic, you need a lot more than two sentences to really make it work. All of these ideas need more skin on their bones.

Bonus points for the page layout being really nice.

Very useful in detailing backgrounds for magic using characters
