The only item I looked at was the armor and only the level 3 version. I didn't realize the bonus increases with the plus on the armor. That's pretty handy. Not a big fan of the power on the armor though. Being daily, the once a day thing isn't all that great, IMHO. I have found the Shadow Warlock Armor to be awesome! a consistent +2 to hit cursed guys is fantastic and some other feats really make this armor even better.
Your armor certainly fits your character concept though, as does mine, since he is MC'd into rogue which also gives me the ability to pop SA at any point I choose as oppose to when circumstances dictate.
I had missed that armour when I was working up my character concept. It would work quite well with my character, as it's very tough to stop me from getting Shadow Walk as the character has an at-will teleport 3 (hopefully soon to be 5). I don't know if I'd have taken it even if I had seen it though, as I'm the designated courtier of the group. Our high CHA cleric seems more adept at picking fights than negotiating, and the rest of the party has 9 CHA. Damned min/maxers.
I've just finished my adjustments for this Friday's session and added a Strikeback Tattoo, in addition to the Khyber Shard. With the amount of criticals that I take, I'll likely get that +2 bonus almost as often as you do
