"Sure it has more than the Dark Forge, but it's the same AC and less INT and DEX than enchanted adamantite plate."
Too bad you're comparing it to CULTURAL smithing. I'm sure if I compared these to Imbued Steelsilk I'd probably side with Imbued Steelsilk (not caring to check, actually) but I don't have 1000 platinum to blow all that often and a high level enchanter at my disposal.
These are all right, especially for Iksar.
