Hey Flooter, this is a good point and a fresh perspective, yet there is something that still doesn't add up:

This basically means that there is no need for the existence of such thing as the Amulet of the Lost Voices, at least in its current form. If this spell is necessary for pushing through the story points, then scrolls would suffice. Once again, I see the issue in the simultaneous existence of the amulet and the sheer abundance of these scrolls. Why do you think I have 10 scrolls in my backpack by the end of EA? Because I didn't need to use them, I had the amulet. See? The least good they can do is restrict the spell to being 'once per long rest'.
