This extra skill is an upgrade to the regular Listening skill. It increases the range one can hear. It also increases the thickness of barriers that a player can hear through. Finally, it can allow a player to detect the tone and pitches of sound. This helps better determine a player's location.
To obtain this skill, a player needs the Listening and Tracking skill. The player must also practice combat through the use of their ears for 45 hours. It will then unlock and replace the basic Listening skill.
