TYPO (R1) - In the special rules of section 1, "the Betrayer" should instead be "the Colorless." For both of the boss's specials, consuming elements only affects the summoning. The other parts of the specials go off regardless.

Note that the Crystal of Zenith and Sphere of Midnight are not actual items and have no use outside this scenario. Use numbered tokens to keep track of who has them. At the end of the scenario, win or lose, these two "goal" treasures are reset so that these two items can be looted again, just like any other "goal" treasures in the game.
