The Lazy GM: Undead and Other Fell Foes is one of those products that makes a GMs life a lot easier. The product presents a bucket load of statistics blocks for numerous undead and other creatures, using class levels and monster advancement to generate an assortment of powerful foes of different abilities and challenge ratings (ranging from CR 1 to CR 24). Of the two dozen odd base creatures that are included in this product, hundreds of additional creatures are created in a variety of forms, shapes and sizes. The choice of class levels and advancement HD is well balanced against the creature's native CR, and make sense within the culture of the base creature. The majority of creatures in the product are undead, but numerous other foes are presented such as Howlers and Yeth Hounds.
This is an extremely useful product overall, crafting accurate statistics blocks that can add a huge amount of variety to any GMs game. With the product designed with the 3.5e OGL in mind, it might not be that compatible with the Pathfinder RPG without some modification, but players of the 3.5e OGL can do a lot with this product. Combined with all their other Lazy GM offerings, one never really has to create another stat block from scratch again. Creative Conclave have done it all for you, true to their product slogan of 'We Work, You Play!'. I have to admit though, that I wasn't as enthusiastic about this offering as I have been in the past about some of the other Lazy GM products. It's not that the work isn't spectacular, but rather that I felt it lacked the spark when churning out the statistics blocks. It looked more like an exercise rather than an attempt to also create unique and interesting creature combinations. I really liked the categorization of the creatures according to 'roles', another aspect of the product that makes it easy to use and pick the creature you want based on CR and purpose. Nice product, perhaps not the strongest offering in the Lazy GM series, but still superb value and usability.
