Curse of the Depths (New Cursed Book / dimming light)

As we saw in the Minecon preview of the deep dark, the lighting would occasionally pulsate; the dimming light during the Warden’s presentation. While re-watching that clip, I wondered about the implications of pulsating light and how players could use it for various projects. So, why not have another Cursed Book that adds that pulsating/dimming light mechanic to helmets. While players would not normally want this curse on their helmet, it could be very useful for players who are wanting to make spooky builds or experiences.

Ideally, this cursed book or curse would be findable like the other two curses, curse of vanishing and curse of binding, by only being found as loot. In the case of this cursed book, it would make sense if it were findable below y level 0, or in the deepest depths / deep dark.
