Grudge Tower appears on Paths 3 and 4 of Yomotsu Hirasaka within the Midnight Channel. It will cover its weakness with White Wall and attack using Fire skills. After being defeated, it may drop a Crown of Truth. Seeling 4 Crowns of Truth at the TV extension of Daidara will unlock the Tajikarao Sword for the protagonist.
In Golden, Grudge Tower has no means of protecting its weakness to ice. It can neutralize a party member's elemental resistance, and take advantage using single target spells of the four main elements.
Grudge Tower appears in the 2nd Block of the Theater District. It attacks with single- and multi-target Elec skills, and Eigaon. When defeated, it may drop Tower Cache and Tower Pillar. Tower Cache is used to create the Mjolnir for Shinjiro*, the Hades Bow for Yukari, and the Tonbokiri for Ken.
