The Wrathful Book later reappears as support for the boss on the 20th floor of Antenora within the Abyss of Time, the Primitive Idol, along with the Shouting Tiara. Its sole focus during the battle will be to use Stagnant Air and Infuriate to Enrage the party. If it is successful, the Shouting Tiara will respond by casting Tetrakarn, which may result in afflicted party members KOing themselves by attacking the barriers. The Wrathful Book should be prioritized as a target, but it has the Evade Fire ability to help avoid its weakness during battle, making striking its weakness something of a chore.
Wrathful Book appears on the first Path of Yomotsu Hirasaka within the Midnight Channel. It will use Tetrakarn or Makarakarn on itself to avoid damage. Once defeated, it may drop a Prophecy Orb. Selling 4 Prophecy Orbs at the TV extension of Daidara will unlock the From Zero handgun for Naoto Shirogane.
In Golden, Wrathful Book will attack with Crazy Chain and inflict Rage on party members, amplified by Rage Boost. It may also erect physical and magical barriers. It protects its weakness with Dodge Physical.
