Absolutely excellent! The "Elements of Magic" series of books are the essential resources for a true magic system. With this expansion, the magic can be brought more easily into a D20 Modern or D20 Future campaign. I continue to be amazed by the scope, yet simplicity, of Elements. I just wish EN would continue (books of Epic Spellcasting, Spell Books, Magic Item Books, etc., etc.). You can't go wrong with this gem!<br><br> <b>LIKED</b>: Best magic system since Ars Magica (and that's saying A LOT).<br><br><b>DISLIKED</b>: Honestly... Absolutely nothing.<br><br><b>QUALITY</b>: Excellent<br><br><b>VALUE</b>: Very Satisfied<br>
