Maku Tree’s Power: Return to Horon Village. With all 8 Essences, the Maku Tree is fully restored! He gives you a Huge Maku Seed that can break the barrier around Onox’s Castle.
Assault on Northern Peak: Head back to the Northern Peak / Temple Remains area where you entered the last dungeon. Use the Huge Maku Seed on the dark barrier surrounding the castle structure. It shatters. Enter Onox’s Castle.
Navigating Onox’s Castle: This is a final gauntlet. Fight through rooms filled with tough enemies like Darknuts, Wizzrobes, and Iron Masks. There are minimal puzzles, mostly combat. Reach the final chamber.
Confrontation: You find Din trapped in a crystal. Onox appears. Time for the final battle!
Final Boss: General Onox
Phase 1: Armored Onox
Onox wields a large ball and chain. Avoid his swings and ground pounds (which stun you). His front is heavily armored. Use Spin Attacks (hold B, then release) to hit his sides or back when he’s recovering from an attack. Keep moving and attacking when you see an opening. He might try to trap Din under his mace; hit him quickly to stop it.
Phase 2: Dark Dragon
After defeating his armored form, Onox reveals his true form: a massive, dark dragon.
Attacks: He swipes with his claws (jump/glide with Roc’s Cape), breathes fire (run/jump away), and tries to crush you with his hand (move out from under the shadow).
Damage: You cannot damage him directly with your sword initially. Avoid his hand slam attack. When his hand is stuck on the ground briefly, jump onto it using the Roc’s Cape, then jump again onto his head/neck area. Charge a Spin Attack and unleash it on the large crystal embedded in his forehead.
Repeat: Jump off quickly. Avoid his attacks and repeat the process: bait the hand slam, jump onto the hand, jump to the head, Spin Attack the crystal.
Victory: After enough Spin Attacks to the crystal, the Dark Dragon is defeated!
Ending
Watch the concluding scenes as Din is freed, the seasons return to normal, and peace is restored to Holodrum (for now…). Congratulations, you’ve beaten Oracle of Seasons!
