After navigating through Onox's Castle and acquiring the Boss Key, you will finally confront Onox, the General of Darkness. The battle against Onox has two phases. In the first phase, Onox wields a giant mace. He will swing it and create shockwaves. Use the Roc's Cape to jump over the shockwaves and attack him with your sword when he is vulnerable. In the second phase, Onox transforms into a dragon. He will fly around and try to crush you. He will also summon Din, who is encased in a crystal. When Onox slams his fist, Din's crystal will drop. Use the Power Bracelet to lift Din's crystal and throw it at Onox's head. Repeat this process until Onox is defeated. Congratulations, you have saved Holodrum!
