to conceal the magic of a god...

[Ectoplasmic Bidet]

As Circle magic is described in the books, your idea would require the system to be reworked pretty heavily, though that is fully within your purview as a GM. There are plenty of unique magic powers and effects scattered throughout the Palladium books.

The Physical psionic power of Alter Aura and the Sensitive psionic power of Mask PPE would both be most effective for the least hassle. If the NPC himself doesn't possess psionics, there is the option to use a device created by a Gizmoteer that mimics the power. If you're unfamiliar with them, they're the psychic version of TW devices, with embedded psionic powers that can be fueled at normal cost by ISP or PPE at double cost.

There is also the 9th level Transferal spell. Though it normally hides the caster's PPE within another living being, a Techno-Wizard device or other enchanted object, such as a ring or amulet could serve as a receptacle.

Or the NPC could simply cast spells until his PPE is dramatically lowered and then do some maintenance casting to keep it from rising to a suspicious level.

A magic thing that alter's their aura is the simplest that I can think of.

As to the circle idea. *shakes head* I don't know of any like that.

Marks that just bind the being...rifts china 2 demon stamp something.

items that make a false aura: artifacts in the NB:Nightlands book.

The spell Transferral is a good way of doing this. Temporarily transferring your magic to someone else who can't use it then regain it at the end of the spell.

You should post this spell to the invented magic topic.

hmm...thanks for trying to help. I'll have to just create something fresh. I'll just allow the PCs to know what it is if they are trained in lore: magic (with skill check, of course). I can't believe you liked this Drewkitty! This is a good spell! Me likey!

Something like this:

Spell of Legend: Seal of the Sleeping God
Target: Person, object, or thing that the seal is attached to.
PPE: five thousand to create, none to activate (see conditions for activation)
Duration: Permanent (see conditions for activation)

Seal of the Sleeping God is a marking, carved into the target (2d6 direct HP or MD damage, this damage will not regenerate and is permanently lost so long as the seal remains).

While the Seal remains intact and active, target effectively has no PPE and is not a magical creature. They don't generate PPE, have no reserve, can't use any spells and their magical nature cannot be detected by any means (spells, psionics, sense magic abilities). They are also unable to generate PPE should they die in a blood sacrifice (so long as the seal remains intact).

As for conditions of activation, the seal is composed of a 2d image, carved into the target. Anything which breaks the form of the image, will break the seal. Should the image be reformed, the seal will automatically reactivate. Thus, should the image be placed in a spot which can naturally open and shut (like a mouth or drawer), the seal would break whenever this is opened, and reactivate whenever it is shut.

As for limitations, this spell does not limit any other means of detecting the target, nor does it affect objects which have PPE that are carried, worn by, or contained within the target. The Seal is also broken should the target transform into a shape which doesn't have the seal (a dragon's transformation, in example).

The last limitation on this spell, is that it's casting cannot benefit from ley lines, borrowed PPE, or blood sacrifices. The caster of this spell must actually have five thousand PPE in order to create it. It is this last limitation that is probably the reason it is a spell of legend, as very few wizards are ever able to cast this spell.

If you have the Nightlands book have your NPC use an artifact with the Null Aura ability.

if they have psionics, simply using mask PPE would do exactly what you want to do.

If he dosn't, give him an item that lets him use the psionic.

Also, there is a mudra of imposition, Casted on any Immortal will Lock them in that position forever, until someone else removes it, I forget the counter for it, i believe it involves some sort of Bait artifact for the immortal to touch.

Inflict Murda of Immobility (Chi Magic) effects everyone (outside the caster) the same. 1 save per day after the 1st from the continuing effects.

Freeze Murda: (Chi Magic) only effects those using murda. Implies that when Demons are caught by this spell that they are also inflicted with immobility. Only 'the living' get a save vs magic per day from the contenuing effects.

FM notes: demons in Mystic china are beings of pure chi that can take on physical form. Sort of like if an astral being took on physical form. So while they are demons, they are different from the demons presented in the rifts books. So a Gm will have to decide how she wants the Freeze Murda to effect the Rifts demons since tehy do not use murda.

mudra of imposition
Where is this? I see it not in the Mystic China book.

another option is creating an avatar.. Almost as godly as the god itself, but has the vantage of being able to blend in with the locals.

Isn't Avatar-making that something only Vishnu (and maybe Brahma, though it doesn't say), Nightlords and Mircalla can do? Most gods can create weaker Manifestations (proto-deific power). Deevil Lords can create "fragments" which you'd think would be weaker but it doesn't say anything about reduced stats...

In all cases though I'm pretty sure they're just as magical and supernatural smelling as their parents. But what godly ability to do mean regarding avatars? Is it possession (via AIs) or something else?

Also, there is a mudra of imposition, Casted on any Immortal will Lock them in that position forever, until someone else removes it, I forget the counter for it, i believe it involves some sort of Bait artifact for the immortal to touch.

Don't recall this from Mystic China mudras, something new in one of the Rifts Chinas?
