Divine Power is a sourcebook for 4th edition Dungeons & Dragons that offers more powers, feats, paragon paths, and other options for the divine classes: avengers, clerics, invokers, and paladins. It is not a stand-alone book; it builds on what's presented in the Player's Handbook and Player's Handbook 2.
Like the other Power books, Divine Power is 160 pages, and the font, layout, and general format is consistent with the core rulebooks.
The book features five chapters: one for each of the four classes, plus a fifth chapter dedicated to "divine options" including feats, epic destinies, rituals, and domains for all divine classes.
Each of the class chapters contains a new build option. (The paladin chapter contains two.) These include new class features, such as the Avenger's Censure of Unity, which grants the avenger more bonus damage as more of the avenger's allies surround the target, adding a "team player" build to the current "lone wolf" options -- or the paladin's Ardent Vow, which trades his healing Lay on Hands ability for the power to smite his opponents with increased damage.
Each of the four chapters also contains eight new paragon paths suited to its class. As with previous Power books, the quality of the paths varies. Some are archetypal, such as the paladin's Demonslayer, Dragon Slayer, and Questing Knight, and probably deserve inclusion on that basis alone. Some are bland, like the cleric's Miracle Worker (which, despite its name, is really just a very healing-focused path, with little else to offer). But the majority are interesting or flavorful, like the Avenger's Serene Initiate, a coolly methodical Zen killer; the cleric's Messenger of Peace, which manages to make a quasi-pacifistic option a viable choice for 4e despite the design of the 4e combat system, which tends to discourage such an approach; the paladin's Gray Guard, where the "gray" refers to morality; and the invoker's Adept of Whispers, which is difficult to describe but has possibly the best image and "fluff" of them all.
The fifth and final chapter contains ten epic destinies, which like the paragon paths vary in quality... although it could also accurately be said that it contains four epic destinies, as the first seven are all variations on the "avatar of a deity" concept. Additionally, one, the Chosen, is just a slightly-modified variant of the Demigod from the Player's Handbook, which makes this a rather skimpy offering, all in all. Of course, there are already many epic destinies to choose from, but I would have liked to see more clever ideas here.
The chapter also contains numerous feats across all character levels, 8 new rituals, two pages of new character backgrounds, and a section entitled "Your Deity and You," which suggests how members of each class might relate to the pantheon presented in the Player's Handbook. I find this last section, and the backgrounds, fairly useless, and I suspect most experienced players and GMs will feel the same, but I can see how it might be useful to newer players and GMs, so I won't begrudge the 8 pages they take up.
Finally, it contains the fourth-edition rules for domains. Each domain is a pair of feats which can be taken by a character who worships an appropriate deity. One feat is a Divinity feat and offers an extra Channel Divinity power similar to those in the Player's Handbook. The other is a Domain feat and grants a small bonus to a skill, plus a small bonus when using an at-will power. For instance, the Darkness domain grants a short period of concealment to a character who uses a certain at-will attack and hits.
This is less powerful than the domains of third edition were, but the implementation seems sound, and it's a nice way to further distinguish between different deities. More importantly, it's not a 'must' for divine characters -- some will choose it, but some will spend their feats on other things. Which indicates to me that their power level is just about right.
For the most part, this book lives up to its promises. The design seems pretty solid, and the content adds some much-needed options. There is a little bit of "power creep" present, but mostly it comes in the form of making the cleric a better healer than other leaders and making the paladin a better defender than it had been, both of which were arguably necessary. The paladin was widely considered the weakest defender before, and the cleric is supposed to shine at healing.
The biggest weakness is the lack of any index, combined with a minimal table of contents. This is a common weakness of 4e books, I know, but that doesn't excuse it. There's also some filler scattered about, but I find the vast majority of the core content -- class features, new powers -- strong, probably stronger even than in Martial Power and Arcane Power.
I'm happy with this book. While the content needs a little vetting, that's no different from similar books for earlier editions of the game, and it does what it set out to do. The quality of the Power series remains pretty high. If you don't like the fourth edition, nothing in this book is going to change your mind. If you do, you'll find some interesting toys to play with. It's more of the same, really -- an expansion in the most basic sense of the word.
