Anyway Dungeoneering always seemed very odd as a skill, I rather liked the thought of Engineering in D&D although pretty directly it seems Dungeoneering by borrowing a "underground" and having what should probably be nature sectioned off created skill uses. So I think we need Skill uses for instance perhaps adjusting an environmental feature so its better for leveraging by the hero team.... or create a brand new Terrain Power or Perhaps even a Trap. Finding or Quick Creating hidden features like escape routes some might be via Skill Powers and Martial Practices.
