The Adventurer's Handbook is, in my opinion, a must have. It's at the top of my list of third party products I allow in my games. The Skill and General Feats in this book are fantastic, and that's an understatement. They provide so many fun new options and ways to add spice to characters of all different kinds. All of these feats fill fun little niches, but still have great practical applications in a multitude of scenarios and encounters. Something that also needs to be praised is that they didn't shy away from including 7th level and above feats, something that I think is lacking in Pathfinder 2E, so it's really nice to get a few more options that players can take at those higher levels. Whether you're looking to add a little bit more to your games, without shying away too much from official content, or you're looking to go all out with wild ideas. This is book has got you covered.
