There are eight secret necklaces you can find in the world of Onimusha 2. Each one grants Jubei special powers for as long as he wears it, and each one is equally challenging to obtain. Since obtaining these necklaces require alliances with opposing characters you will only be able to obtain five necklaces during any one adventure. Here is a brief description for each of the necklaces along with a link to the section of the guide where you can obtain each of these powerful items.
Black Necklace - Found Here
This is one of the most powerful of all the necklaces and also the hardest one to obtain. When wearing this necklace every attack Jubei makes is a Critical Hit but he will also lose a significant amount of health from his power bar. This necklace is a great way to rack up massive amounts of critical hits to increase your final rank. The Black Necklace is found very late in the game in the Oni Sacred Place underground, but you will have had to previously obtained three Fossilized Bones from the male sub-characters.
Blue Necklace - Found Here
This necklace allows Jubei to absorb souls at twice the normal rate and also blocks the Gyaran from stealing souls away from you. To acquire this necklace you will need to be allied with Kotaro prior to entering the Demon Caves. Kotaro will then appear and reveal a secret wall section that gives you access to this prize.
Green Necklace - Found Here
This is a very useful necklace as it allows Jubei to see the 15 hidden Demon Treasure Boxes scattered throughout the game. Without this necklace these boxes are totally undetectable. Since you cannot afford to wear this necklace all the time you may want to visit the Hidden Demon Treasure Boxes section of the guide for clues as to when and where to put on this necklace. To obtain this necklace you will need to be allied with Magiochi prior to returning to Yagyu Village. You will encounter Magiochi at the Dragon Pond and he will give you a Saiga Bomb you can use to blast some loose rocks near the Dragon Shrine and reveal this necklace.
Orange Necklace - Found Here
This is another useful necklace as it allows Jubei to see hidden red soul clusters scattered throughout the game. There are 38 hidden clusters and without this necklace you will never find them. Since you cannot afford to wear this necklace all the time you may want to visit the Hidden Soul Clusters section of the guide for clues as to when and where to put on this necklace. To obtain this necklace you will need to help the man in the shop in Imasho Town convert a piece of chalk into a slice of melon for his sick father. This is explained in greater detail in the guide.
Purple Necklace - Found Here
This powerful charm allows Jubei to perform magical attacks using only half the normal magic power. You find this necklace on the final level of the Purple Phantom Realm.
Red Necklace - Found Here
The red necklace causes enemies to release more red soul energy when they die - a great tool for enhancing your weapons and armor and also for factoring in to your final ranking. Note that while red souls are increased yellow and blue souls are no longer released while wearing this necklace. To get this necklace Oyu must be your best ally when you enter Oni Sacred Place. Just after obtaining the Circle Key you will encounter Oyu and shortly thereafter a hidden area is revealed containing this charm.
White Necklace - Found Here
This powerful necklace allows Jubei to heal himself simply by standing still while wearing it. This is a slow process but it will allow you to save your healing items for the boss fights or those times when you simply don't have the luxury of standing around for several minutes. To get this necklace simply speak with the owner of the store in Imasho Town after buying out his inventory for the third and final time.
Yellow Necklace - Found Here
This necklace allows Jubei to absorb yellow soul energy from demons while they are still alive. Simply stand over a fallen enemy while wearing this necklace and press R1+
to steal their life force. To get this powerful necklace you need to be allied with Ekei prior to entering the Oni Sacred Place.
