The Second Story of Soma Cruz(Castlevania: Dawn of Sorrow Part 2)

Following a bit of minor progress, we work our butts off and acquire the Soul Eater Ring.
You can get this ring early in the game by acquiring 9 Zombie Souls(There is a set of 2 located left of a save point in the Lost Village. You can dispatch them with the Student Witch Bullet Soul) and buying 9 Brass Knuckles from Hammer.
Have Yoko Belnades fuse the 9 Zombie Souls with the Brass Knuckles to get 9 Cestus weapons.
Sell them to Hammer for a whopping 27000 total(3000 per Cestus that you sell).
Repeat many times if you want the Soul Eater RIng.
