Forum:Hood of Oblivion

I've been trying to farm a Hood of Oblivion. I've been farming the area with the Midnight Helix, because you can get 2 Bitterblack Armor Level 3 there. I have been farming for about 3 weeks now (literally and I know that's sad), I have about 20 coats of shawdow and probably like 30 gauntlets of shadow. That is all it literally gives me, coats and guantlets. Please can someone tell me what I am doing wrong? I'm ready to smash my PS3 I'm so incredibly upset.
