I must venture into Shard of Hate: Eye Spy [Tradeskill] and listen in on the Mistresses of Hate's conversation using an Arcane Ocularum, which requires 3 components - an Ire-Bound Frame, a Resident Attunement Lens and a Sensory Delver. Resources for these components must be gathered within the Shard of Hate and create at the Fiend Fount. The Arcane Ocularum can then be crafted at The Malicious Mixer and used on a fiend near the mistresses.
