We wanted to make an awesome Warlock set that would look great on Orcs (many would argue that orcs don’t look great in cloth gear). We had to find the perfect shoulders and build the rest of the set from there, and these black feathered shoulders called out to us. Since daggers are fitting for Warlocks we decided to go with a 1h + offhand set, and we just love the combination of this dagger and grimoire together. The demonic helm is just the cherry on top for this green fel looking set.
To gather all the pieces of this set will take some effort on your part, a lot of the gear comes from various different raids so it might take you a few weeks to get lucky with drops/lockouts.
