Now let's talk about synthesis. Below the Lost Village warp room, there is a save room. Below the save room, there is another room. Go to this one to find Yoko Belnades. Walk to her and press 2. She will offer to improve your weapons if you have the appropriate soul. (She doesn't take the soul, you only need to have it.) There she says which soul you need to enhance the weapon. If you got the soul of Alastor, she will turn the greataxe Bhuj into a Death Scythe. (If you used Bhuj before, you will love this weapon)
