Zombie, Ctulhu, Akmodan II.

Guide to defeating Akmodan II in Castlevania: Symphony of the Night's Inverted Castle. Includes strategies, item locations, and walkthrough for Orlox's Quarters and Royal Chapel.

After returning to Orlox’s Quarters via the red door, head left towards the Azaghal. The next room contains Ghost Dancers and a Malachi. Avoid the Malachi’s green projectile and defeat it. Continue to the subsequent connecting room, then proceed to the room with a red door on the left and a drop-off. This red door grants access to the area’s teleporter.

Drop down the opening, hugging the right side to find pots containing a Shield Potion, Luck Potion, and Manna Prism. At the bottom, navigate the spiked ceiling obstacle. You can equip the Spike Breaker armor, use the Mist form, or double jump. Be cautious of the Ghost Dancer placed to disrupt jumps. In a pot at the end of this spiked room, you’ll find an Aquamarine. An opening above this pot leads to a new area.

In the large room, you’ll encounter Karasuman enemies, which now function as normal enemies in the Inverted Castle. Their rare drop is a ring. The first area to explore is through the top-left door of this room.

In this new room, you’ll face Flying Zombies, whose upper bodies continue to move after separation, and a Ctulhu. After them, find a Life Max Up. The next section has more Zombies and Ctulhu. In this area, a breakable floor near the third candle (where the Sword Card was in the normal castle) reveals a secret room containing a Heart Refresh. This item restores 500 hearts and is best saved for use with the Duplicator.

Exit the secret room and head right, through the door connecting Orlox’s Quarters to the Royal Chapel. Backtrack to the large room with Karasuman and take the top-left entryway again. Follow the linear path to its end to find the Alucard Mail. This completes the collection of Alucard’s starting equipment, though some items like the Mail and Necklace of J are not as effective now.

Fly down from this room and use the save room. After clearing these areas and obtaining map coverage, proceed to the boss located at the bottom-left of the large room. Before the boss door, a Shuriken can be found above you in the hallway.

Akmodan II

Akmodan II is the final normal boss. Equip the Topaz Circlet to mitigate poison damage from his yellow gas cloud attack. Akmodan’s primary attack is a slow, stretchy hand thrust. He is vulnerable to multiple attacks. Upon defeat, he dissipates, and you will receive the Rib of Vlad, the final relic needed to fight Dracula. In the room where Akmodan was fought, a door on the right leads to a Heart Max Up.

With all main areas explored, focus on completing any missed map coverage, especially in water areas. Afterward, proceed to the Inverted Clock Room (Marble Gallery), suggested for level 45. A Heart Refresh can be found here.
