Bests & Worsts Reviews from Amazon

Xanathar's Guide is to the Player's Handbook and Dungeon Master's Guide what Volo's Guide is to the Monster Manual; for everything in those two books, here's some more. Lots of intriguing new subclasses, some of which will doubtless make some of my players want to make new characters. (The Samurai class in particular is almost certain to appeal to my fighters.) For the players who are into role-playing more than game-playing, there's a pretty nice section devoted to helping players flesh out their character's background even further. For the DM, new tools, new treasures, and new spells. Is Xanathar's Guide a must-have? Not in the sense the PH, DMG, and MM are. Nothing in here is essential to playing the game, and a player without Xanathar's Guide is in no way handicapped compared to one who does. Do I recommend it? Without a doubt. Having played with 5th edition for a few years now, I really feel this book helps refresh the game.
