Collector has a few, but they're mainly used in rituals he hasn't learned how to do.

Peyton: I heard you need to do a ritual

Collector: I don't need a ritual, I need a trade. If I give mors a light soul he'll let xander and kinyani live.

Peyton: *Proceeds to hand Collector the Lord's light soul* I got this after I beat the Lord in combat

(I just realized it was called a PURE soul not a light soul)

Collector: ... I'm not even gonna ask how you got this.

Death: The Lord is actually way too busy to come down and take care of it himself. He sent down one of his children in mortal form, and when they die they simply return to him.

Mors: Sadly you'll have to inflict great pain on a child *laughs a bit* but not an ordinary child, a special one

Collector: *pulls out the pure soul Peyton gave him*

Not from a child, but from the Lord himself.

Mors: Really? Not even the Lord has the soul i want

Collector: well technically it's a mix between a light soul and a pure soul, but it should get the job done.

Mors: Oh really? *The symbol on collector starts to glow and collector starts feeling pain*
That Soul isn't the soul i asked for

Only one individual has it, a True Pure Soul, TPS for short

There are only legends, but i already have the True Dark Soul, and i only need it's counter part to complete my plan, so no soul will ever escape from me ever again

Mirai: Excuse me what the f**k

Mors: A TPS is a soul powerful enough to revert my mistakes

Mirai: *inherits the power of the true dark soul* No! I'm stopping your madness now

*collector barely reacts*

Collector: you think your little spell scares me? I did my research, And I can make it backfire. Easily.

*The symbol glows blue and mors falls to the ground*

Mors: Heh *he gets up and raises his arm* *the symbol becomes purple* *suddenly collector feels even greater pain* It's my magic, it's controlled by me, the only thing that can alter it is my own blood, so tell me, did my son help you sabotage my magic?

Collector: no, but I have the very thing that made this timeline. So...

*The symbol glows even brighter blue and mors begins burning*

Why wouldn't I be able to alter your magic?

*mors stops burning and collector is pushed some how to the ground*
Mors: If you dont get what i want, that symbol will go on some one i know you love

Collector: how about a different deal. I close that rift to the afterlife myself, THEN you leave the inklas alone.

Mors: Really? Only a being from the afterlife can close the underground, Shouldn't that make sense?

Collector: I'll figure something out.

Mors: Listen i already have a Powerful Dark Soul, give me the Pure Soul and it's done, my son should already be searching for it

Collector: then why don't you just take this one? It's literally from a god, how much more powerful can it get.

Mors: Do you think power matters here? You can be an all powerful being but still have a weak soul, this person has a soul no one else has, you should be searching for that, 4 days left
