This skill allows the character to move and/or perform actions quietly. Outside of detailed action time, a character may move a distance in meter equal to his/her base action phase before having to check his Stealth BCS again. In detailed action time the character has to make a successful BCS roll every turn to maintain his/her stealthy movement and/or actions. The GM should make the rolls, as the character would only know if he/she were discovered. On an unsuccessful attempt the character get a second chance, by rolling a Speed CST. If successful on the Speed CST the character is not heard. On a critical miss the character is automatically heard.
