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.
