In your sets, equip in A: unarmed, your favorite armor, and Soul Eater Ring. In the Souls, equip Imp[B], Black Panther[G], and for enchant, you can use anything. In set B: use any weapon, your favorite armor, and Chaos Ring. In Souls, equip Succubus[B], and any other guardian and enchant, though Treant[E] is recommended. Then, go to the place in Wizardry lab where you destroy the ceiling. Find the fountain in the lost village, then fall all the way down, and turn right to find the Iron Golem. Activate Imp[B], and punch the thing quicklyand it should die. If you get low on HP or MP, use the Black Panther[G] soul to dash to the room on the right, then switch to set B. The Chaos Ring will replenish your MP and you can use the Succubus[B] soul to get HP from the ghosts. When the process is done, switch back to set A and continue fighting the golem.
