The shadow band ring from AV, level 27 ring, seems like a rogues best friend.
Shadow Band Level 27
Property: Gain concealment.
It's power as a minor action gives you total concealment until the end of your next turn, if you've hit a milestone for the day it's until the end of the encounter.
Is total concealment enough to grant combat advantage on every attack you make? I know it negates the possibility of any creature having combat advantage against you because you have to be able to see a target to have CA against it, and total concealment means nothing can see you. It also prevents any and all OA's from triggering since you again can't be seen. But does it mean that they are effectively "blinded" to you or that you are effectively "invisble" to them. Does it instead mean that after every attack you would need to make a stealth check to hide from them again even though they can't see you?
The property of the ring alone means that as long as you stealthed in total cover or concealment before moving out into the open you could walk around without anyone ever noticing you as long as you never attacked or talked etc as long as their passive perception didn't beat your stealth roll.
In the end any way you look at it a ring that grants +2 to all defenses vs ranged or melee attacks (-2 to hit from concealment) is pretty nice, when you toss in something like a cloak of distortion to give a -5 to being hit from a ranged attack if more than 5 squares puts you at a nice +7 defense vs ranged attacks from more than 5 squares out, hmmm maybe these items are actually an archery ranger's best friend.
