Dark Stalker II: Ignore the Movement Speed penalty of Sneak. Decreases the time it takes to enter Sneak by 50%.
Dark Stalker increases your movement speed while sneaking to approximately standard running speed, and also allows you to enter stealth more quickly at night or indoors.
Fixed an issue where you could stack the Dark Stalker passive with the Night's Silence or Shadow Dancer's Raiment item sets to move at mount speed. This is no longer possible—you get the bonus from either Dark Stalker or Night's Silence or Shadow Dancer's Raiment.
Fixed an issue where this passive ability was reducing the Movement Speed penalty of Crouch by 50% instead of 100%. This ability's tooltip has also been updated to better describe its bonuses.
