Reformed Okina can be found in the 4th and 5th Worlds of Magatsu Mandala within the Midnight Channel. They will attempt to use Old One on the party while taking advantage of Enervate Boost and use Electricity skills along with Mind Charged attacks. While it is set as its Weakness, Reformed Okina will only take half damage from Fire skills. After being defeated, they may drop a Knowledge Staff. Selling 4 Knowledge Staffs will unlock the Hattori daggers for Yosuke Hanamura in the shop.
