From publisher blurb:
Learn the secretive ways of the wild elves!
With the Wild Elven Ranger, a new 13 level elven variant class for Adventurer Conqueror King and Labyrinth Lord, you can play these mysterious elven race in just about any OSR game. This class introduces the wild elf, a slight twist on the normal elves in old school games, and presents a variant interpretation of the elven ranger class, with a greater emphasis on mystical abilities, like speakiing to animals and eventually gaining a totem animal. These elves are even more reclusive than their high elven breathren, but now you can peak into their world!
