Hiding out of plain sight, or moving with minimal sound are covered by the Stealth skill. Cover and conditions, such as darkness or loud background noise, improve the grade of the skill according to the specifics of the environment. Similarly, adverse conditions, such as a lack of cover or a quiet night will decrease the skill’s grade. Circumstances also affect the difficulty of the attempt. For instance, a warrior wearing heavy armor can easily conceal themselves behind a wall, provided they stand still or move very slowly, whereas moving quickly might cause their armor to jingle.
