The scout is a swift explorer moving unseen through hostile territory observing, probing, and gathering information about the terrain, threats, fortifications, and the movements of enemy forces. Many scouts employ skirmishing tactics to harry and wear down small enemy forces.

At 3rd level you have learned to read signs of recent events in the terrain. After you spend 1 minute studying an area you can identify some of the events that occurred here in the past 24 hours. Choose three questions to be answered by the dungeonmaster:
Starting at 9th level, your speed is increased by 10 feet when you aren't wearing heavy armor. In addition, you may move through a space occupied by a hostile creature of any size while you aren't wearing medium or heavy armor and are not wearing a shield.
Starting at 13th level when you roll initiative and are surprised you may use this ability: you are not surprised. Once you use this ability you may not use it again until you complete a short or long rest.
At 17th level you have honed your skills of observation so sharply that you can read the terrain and form a rough map of its features in your mind. While aboveground, outdoors, and not in heavily obscured (or worse) conditions you may spend 1 minute observing the surrounding area in undisturbed silence. You gain a mental map of all aboveground pathways and water features within 1 mile that are not concealed. The DM may also apply your passive Wisdom (Perception) as a check to discover hidden ways and secret doors within the same area as if you were standing near the hidden feature. Once you use this ability you cannot use it again until you complete a long rest.
