This is a really good elf supplement, the variety of things you can use to customize your elven characters is staggering; you could have an entire party composed of elves, and they would all feel quite different. The story and racial background details make elves mysterious and deadly, to the point they could feel more like outsiders or extraplanar beings.

The information for both 5th Edition and Pathfinder is useful and clearly laid out. It feels that it leans a bit more towards the Pathfinder side of things, but that's minimal. An impressive amount of subraces, abilities, feats, archetypes, classes, spells, equipment, and so much more, without even taking the meaty background information into account.

Elf lovers rejoice! This is one of the best supplements of this particular race, you kinda wish they give this same treatment to the other standard fantasy races.

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.
