I was fighting the Duergar at the docks for the Myconids. I cast Tasha's Hideous Laughter on Novice Garmor and succeeded. The conditions he had on him were, Enlarged / Hideous Laughter / Threatened. When hovering over Hideous Laughter it says "All attacks made withing 10ft of the creature have Advantage against it."
Using Astarion, I tried to backstab him. However, it would not let me and had the red text saying "You must have Advantage to use this ability".
Am I missing something here or is this just bugged?
