Okay, so I gave up on crafting Demonic in December, but now I'm back on it since I'm bringing up an Alt. To answer my own question, I scoured Slaveleia's thread here...

And this is my synopsis

Best places to farm Glyphic Blade Steel (which now has ZERO availability in CS) are:
Nuri's Madness - Nuri drops it
House of Pain - Tiny & Tinier twins
Lions Den - Zookeeper (tho unlucky for some)

Best of luck, other late Demonic crafters!
