First off, let me say that I generally enjoy Rite Publishing's material. Even this product has some really good ideas, and its a good concept. I think that skills could use some more options as well. Unfortunately, while some new options really are new options, some are just begging to be abused, and others really should be feats when you look at the overall design paradigm of Pathfinder.
Among the good ideas? Guidelines on bribes based on level, and what kind of information you could get from an autopsy. Great, these are things not currently addressed. Exactly what I'm looking for.
Then some things get clunky. Skill uses that require you to have a minimum number of ranks in other skills seem especially cumbersome. It's not that there isn't a certain logic to it, but at the same time, it complicated and doesn't resemble other rules in the game regarding skills.
Then we get into using diplomacy for calling for a truce, and other skill uses that allow for a very specific use of the skill. Too many players already get hung up on forcing NPCs to do something with social skills, and skill uses like this just encourage "diplomacy as a charm spell" gaming.
Then there are skill uses that allow PCs to ignore difficult terrain (already done with other mechanics that aren't just higher DCs, and kind of messes with people that took those options), and skill uses that allow for shutting down or reprogramming constructs (definitely something I'd require a feat CHAIN for, not just a really high DC).
I really wanted to like this product, and there are some good ideas in this, but it would take too much "this is in, that is out" GM editing, and would open up too many questions compared to just not using the product outright. Here's to more skill uses that are brand new ideas and not just ways to circumvent existing rules with high skill DCs.
