I was planning to add some IM items to my gear, but it seems that most of the IM items cannot be forged / upgraded and only avaialble to upgrade with SS.

about the cape, since i am use a wing, do you think the wing is better at max upgrade or the cape?

wing cannot put spars in it so is the cape better? but then i wont be using any magical sets items so the double socket wont applied to cape.
