Boots of the Vale - 2013 (Gold)
If outdoors, these allow the rogue wearer to perform a sneak attack without the normal one round delay. (The sneak attack attempt does not necessarily need to be done on the first round of combat.) Rogues without these boots must take one round to slowly move into position before attempting a sneak attack.
