The Dungeoneering skill represents knowledge and skills related to dungeon exploration, including finding one’s way through underground complexes, navigating winding caverns, recognizing subterranean hazards, and foraging for food in the Underdark.
Training in this skill represents formalized study or extensive experience. Those that have training in the skill can also identify creatures of the Far Realm.
Make a Dungeoneering check to recall a relevant piece of lore about an underground environment or to recognize an underground hazard or clue (see “Knowledge Checks”).
Examples of dungeoneering knowledge include determining cardinal directions while underground (hard DC), recognizing a dangerous underground plant (moderate DC), spotting new carvings or construction (moderate DC), and noticing a change in depth while exploring an area (moderate DC).
