This feat represents your knowledge of the wilderness. Characters with this feat are granted special quest-specific dialog options/object interactions that classes without this feat otherwise could not perform. It may also allow certain skill checks to learn insight into specific situations.
Bards and Stormsingers receive this feat at levels 1, 3, 5, 7, 9, 11, 13, 15, 17 and 19.
Verbatim from the release notes: Many classes now gain the "Arcane Lore", "Religious Lore", or "Wilderness Lore" feats every level, which may modify certain dialog options or come up in other ways during quests.
