Help with onoskelis ..... possibly?

[Veil]

I will be frank and say I have never heard of this entity.

The most I can advise is this –

The Seal of Manifestation

It has one Simple function: To prevent/Kill any impostors or wandering spirits that are interfering or could interfere with your evocations, Invocations, possesions, or magic. I originally made this as my own personal consecrated seal for Azazel. But then i was like, “I could make a seal outta this for another purpose” So this is the result. I offered it to the Infernal Divine and they Accepted it. Its no longer mine. Its theirs now. Specifically, Azazel and Hecate stepped forward to cons…

To make sure you are actually contacting the entity rather than an imposter.

Good luck
