urban explorer

You are particularly familiar with urban and sewer environments and are adept at traveling and surviving in such regions. When you make an Intelligence or Wisdom check related to this terrain, your proficiency bonus is doubled if you are using a skill you’re proficient in.

While traveling for an hour or more in a city or sewer system, you gain the following benefits:
* Difficult terrain (such as crowds, rubble, or sewer muck) doesn’t slow your group’s travel.
* Your group can’t become lost except by magical means.
* Even when you are engaged in another activity while traveling (such as scavenging, navigating, or tracking), you remain alert to danger.
* If you are traveling alone, you can move stealthily at a normal pace.
* When you forage (scavenge for supplies/rations), you find twice as much food as you normally would.
* While tracking other creatures, you also learn their exact number, their sizes, and how long ago they passed through the area.
