I purchased this book as a supplement for my home-brew epic level campaign. I wanted to increase te spell selection for my characters and was interested in the time magic spells contained.
The spells in the book are very creative, but some are a little complicated in effect or wording. Several of my players have indeed decided to utilize some of the spells in the book, and they enjoy them very much. Ii would be very interested in seeing a v2 of this book done with some clarification and additional editing.
We will still continue to use the material as-is, because of the wonderful creativity and fun that it brings to the game.
