[Archer: Is it Bind like the spell?]
[Black Witch: Not so alike but the name is the same. The Bind Curse was based on the true love when two souls are meant for each other and blah blah blah. The Curse will Bind one soul to another forcefully. Where one will command the other freely.]
[Archer: The spell description is exactly slavery. This is awful.]
[Black Witch: You want to do it or not?]
[Archer: Keep explaining.]
[Black Witch: The soul can enter under your command or vanish. But then you have freely control over the body. Which would be the sword on this case.]
[Archer: Anything more that I need to know?]
[Black Witch: While using it on a soul that is more powerful than you maybe you'll need to use other formulas to counter the resistance.]
[Archer: Okay.]
