I wish I could give this more than just 5 stars.
I have always run campaigns that went beyond the old 20th (and in late 2nd edition 30th) level cap, but had to make up my own rules for running them. It always upset me that just as characters got tough enough to be able to handle he truly epic tasks and quests that all players dreamed of doing, they were supposed to be put out to pasture. So, when this book came out, I was utterly speechless with anticipation, and to my utter joy, I found it to be everything I had been craving all these long years, a return to the near insanity (and endless fun) of the original D&D 'Immortals' box set.
It's a hefty book, packed with all new rules for taking your players, villains and monsters to any level you want. Well presented and well wirtten, it gives advancements for all the base characters classes, as well as for the prestige classes from the Dungeon Masters Guide.
It feature a ton of truly epic feats (imagine having all of your spells quickened or silent without altering their level, or being able to slice someones head off with your bare hands), epic magic items (you could now truly create a +12 Hackmaster if you wanted), epic spells (this time they got it right, we are talking SERIOUS magic here, not underpowered 9th level spell clones), my personal favourites, the epic monsters (HOW MANY HITPOINTS? AN ARMOUR CLASS OF WHAT?), and a whole ton of information about running and balancing epic campaigns.
Stunning artwork is found through the book (check out the Xixecal), and everything is laid out in a sensible and intuitive way.
I cannot stress enough what a great addition to your D&D rules set this work is, if you truly want to run a high fantasy campaign. Coupled with Manual of the Planes and Deities and Demigods, it arms the GM with the tools and rules for crafting incredible, memorable adventures that will leave your players both staggered ("It did how much damage?") and awed ("I did how much damage?"), and will keep you happily going until they achieve godhood.......or get killed and eaten by a Paragon Beholder! Buy it!
