I feel as if there are many valid options for the cape augs depending on what you wish to do, and that many of the augs are so potent you'd want multiple capes just to have access to such strong gear. I'm doing a bit of testing on avatar levels vs attributes and trying to nail it down but it may be a few days because I had to work late and I keep getting d/c from the game and logins take 15 mins, so no way I can get a cape tonight... or who knows if congestion issues continue.
Here is my initial work I can share tho:
The early levels are very strange to say the least, and acc overtakes attack after you put on an icaller and were merging before that... on top of that the slope of the line is totally different after you put on an icaller but at least then it's a straight line, it seems after icaller boosts are greater too, meaning +1 lvl would mean more not less for ilvl avatars. I'm not sure if this changed or prior tests were inaccurate.
One thing I look forward to testing is if the cape and mitts will work interchangeably for same values. I'll likely have to go to pvp and have someone keep changing INT gear on a player casting nukes to nail down avatar INT and could do VIT also for STR and see if they match up.
I also thought it very interesting the source of the name on the cape:
