Actually Dexx, since you asked:
First and foremost, this is usually where I say "I could tell you but then I'd have to kill you" but I think I can make an exception this time.
(besides, all your souls will be mine eventually anyway, so it doesn't really...):clears throat:
Anyway, I have 3 choices when removing the soul, what exactly I want to do with it.
A. Trap the soul inside my arm until I can get back to my home and be cleansed of it forever.
B. Fuse my soul with it so that I gain all their knowledge, power, etc. while at the same time remaining my self.
or
C. Use that soul as a healing device to mend all of my(or someone elses) current wounds. This technique is also used in terminally ill patients, where I would remove their soul and reimplant it in hopes that this would cure them.
Got it?
Actually, Fitch, I have never missed. However I do recall an unfortunate stuation where during removal of an enemy's soul and his last ditch effort was to stab me in the chest. This cause me to lose concentration. The out come was, I didn't get the soul, but neither did he. It will forever be in limbo, without a reason or destiny.
Thank you. Oh and Dexx, there is one good use for a soul like the one you described(besides living in you that is) I could remove it from you, forcably insert it into someone else, and your soul could spend the rest of it's days drive them insane. It's actually quite fun. The only draw back is that the process is irreversible.
That's just it. There aren't supposed to be too souls. Therefor, you, being the uninvited soul, cannot be fused with the other soul because it is trying to get rid of you. It is a constant battle that eventually you would win. Main reason for that is that a soul gains more potency after being removed from its own body. Think of it like this. The soul has been in a confined space the entire existence, and all the sudden, it has room to stretch out...flex it's "muscles". See what I mean?
