There are a couple perks i have been wondering whether to get in the sneak tree. first off there's "Silence." when it says walking and running does not affect sneaking, does it mean that walking/sprinting outside of sneak doesn't effect the enemies detecting you (within reason)? I mean obviously if you try sprinting across LOS of an enemy they will see you but as long as you are out of a certain distance from them they wont notice you?

And then there's "Shadow Warrior." say with a bow i shoot at my target, it starts searching for me starting with where i am (I havent moved from where i took the shot), i can unsneak/sneak and said target will search elsewhere?

Silence gives you a 1 point (100%) muffle effect permanently. Muffle works whether you are in or out of sneak. With this perk it is very possible to run up behind people and have them not detect you.

Shadow Warrior takes you and your enemies out of combat by applying a very short invisibility buff. If they are unable to detect you (which is easy with high sneak and perks) then they will search for you and soon after go back to their usual routine.

Basically..

Player crouches -> Enemies can detect you within this one second~ invisibility period -> Combat continues
Player crouches -> Enemies cannot detect you wtihin this one second~ invisibility period -> Enemies search for player


Shadow Warrior can be used to get in combat sneak attack criticals and to quickly lose enemies without having to entirely flee the area.

ah, thank you very much, i must take these perks later on then. thank you
