The preface reads:
An insistent buzzing, a deafening whine – that can only mean the Duke of Flies is near! Can you overcome the Duke and the vast swarms of flies that surround him, each willing to give its life to defend its master? Kill them, tempt them away, do what you must: there can only be one true Lord of the Flies, and the Duke doesn’t take too kindly to competition…
Additionally, this challenge is available on the official Tabletop Simulator, just load up The Binding of Isaac: Four Souls Requiem+ and select Challenges from the starting game options.
