No, that is wrong. The shield for the upgrade from Fiery Defender to Fiery Avenger drops off an inky SK (level 53 or so) that wanders in Nektulos Forsest named Kirak D'Vil. He paths from the Neriak zone in cave to the POK book and back.
Junk for where it drops. Its gotta be a quest item, that is about the only reason I'd figure for it dropping in those places. Then again, the Jagged Chokidai Spine does drop in Chardok.
Would take good old 10ac mr shield from CB over this though, so this is going a bit overboard on low lvl especially considering it's no drop. Would assume this is a pally or maybe cleric quest item.
