Wardens of the Wild contains options for both Pathfinder and Dungeons and Dragons 5e focusing on the Elves. It covers 6 elven races with paragon classes for each, 2 modified classes, new or collected class options from different existing supplements, and new spells for both editions. They cover lore for the race types as well as lore for the elves in general. I have not had a chance to test out any of the new options for balance in my own games yet but some of the new rules might have to be modified for my campaigns. It was nice to have the 5e rules in here as well, they don’t have as much material out there yet for player options outside of four books. A few of the options are duplicates from Pathfinder's Advanced Race Guide which has been out for a while. I have the pdf version right now but at some point will want to pick up the hard cover of this as well.
