I found this product to be AWESOME! It's not often I give a glowing review with no problems, but this product does exactly what it's supposed to do, does it well, and looks good doing it.

In my game I use the Karma deck to show the favor of the gods. If the PCs do something that the gods might reward then I give them a card to use at a time that they choose. It gives them a bit of a boost and solidifies the importance of the influence of the gods in my current campaign.

The cards give the PC a bit of a boost, some extra damage, an extra little ability or defense. Not enough to completely unbalance the game or encounter, but just enough to tip the scales in a single combat just enough.

If I had only one critique is that it does seem a bit pricey for what is essentially a medium sized set of cards.

This will be an integral part of the rest of my campaign.

Conceptually, Creation Edge's Karma Deck provides a simple and interesting way to incorporate karma, divine favor, or other boons into D&D 4e. You can hand out "karma cards" as rewards for, well, anything you want. A player can then use a karma card during combat to swing fate to his or her PC's advantage. I've been looking for an additional reward system to add to my campaign for some time. I was thinking about just adding bonus d6s that players could add to any d20 roll, but the Karma Cards provide more variety and therefore seem to present a better option.

The cards' benefits do vary in intensity and usefulness, as befits a random pool. For example, one card provides a healing surge, another provides 5 temporary hit points, and another allows you to redo an unsuccessful attack roll. I did not find any of the effects objectionable (in terms of power level or "swinginess"), but of course any DM who likes most, but not all, of the effects can just leave selected cards out of the deck.

Creation's Edge provides many helpful suggestions for how to assemble and use the deck, but for some reason these come at the end of the PDF rather than at the beginning. The instructions are also formatted on cards, which means that half of the instructions are printed upside-down relative to the other half—so you'll need to print out the instruction page as well as the other cards.

I find this product quite fun, and while I haven't firmly decided whether to incorporate it into my current D&D campaign, I think I probably will. However, I must point out the product's great weakness, its poorly-edited prose. The ratio of grammatical errors and stylistic oddities to word count is annoyingly high. There's no need for me to list all the errors here; suffice it to say that I could not find a single error-free page anywhere in the document. Sometimes, the errors or oddities do affect game mechanics. Most significant are ambiguities like the one on Fortunate Ricochet: "Pick a second target up to 3 squares away"—away from whom? I presume that "away from the original target" is intended, but the card isn't clear. Similarly, some cards increase damage such that "Your die roll is equal to the highest possible die roll result," but what if your damage expression contains more than one die? Again, I presume that the author intended for the card to apply to all dice rolled for that instance of damage-dealing, but the card doesn't actually say that. I'm not sure why the card doesn't just read "your attack deals maximum damage," in keeping with the phrasing used to describe the effects of critical hits (Player's Handbook, p. 276). Other errors don't affect gameplay, but are simply embarrassing, such as the not-infrequent use of "your" where a sentence demands "you're." These grammatical errors will not stop me from using the Karma Deck in my games (though they did bring down the star rating on this review), but they do significantly mar an otherwise well-conceived and well-executed product.
