So, we have the Improved Invisibility Spell ...

Type: P / Test: Opp [Int] / Range: LOS / Dur: S / Drain: [F/2] + 1

This is a Single Sense Spell, specifically affecting sight.

Let's say that I want a Multi-Sense version of this Spell, basically Physical Non-Detection. To find the Drain Value, I would only have to remove the Single Sense modifier from the above Spell (-2), and add the Multi-Sense modifier (+0), making the stat-line ...

Type: P / Test: Opp [Int] / Range: LOS / Dur: S / Drain: [F/2] + 3

This Spell would mask all audible, visual, olfactory, (and technically even taste and touch) traces of the subject.

Is this right, or am I missing something?

Astral perception is a sense, and can be removed if the target is valid (astral observers are not a valid target for physical spells if I´m not mistaken).

That said, I´d not allow a custom spell to remove more than one sense.

So one COULD add a mana spell that removes ASTRAL perception that would make one invisible to spirits...

That way it would be balanced since all other kinds of detection exists.

Well, just don't do it when a magician of a Logic+Willpower tradition comes around. An moving seemingly unattached spell is a giveaway.

The issue is that you could theoretically be invisible, but the spell aura is not. You could be completely invisible, even to astral observers, but astral observers would still see that spell aura floating there. The spell can't make itself invisible. To prevent astral observers from seeing the aura, you'd have to cast some kind of sense removal on them. (There could conceivably be an illusion spell that creates a sort of limited sense removal where the target no longer perceives spell auras I suppose... but that'd have to be subject to GM approval. I probably would give it at least the same drain as full sense removal, because the target is not necessarily aware of the change.)

Hmm, what about masking and improved masking (can't remember the term right now)? With the improved masking, you can hide active foci, substained spells, etc..


Or if it too much of a head ache, make it an illusion of some kind (astral wind, swirl, etc...).
Hmm, doesn't conceal spirit power work something like that?
Or do people play that conceal only works on the mundane plane?

Hmm also wouldnt it take two spells: One cast on the physical plane and one astrally.

IT is impossible for a spell to effect somebody on a different plane.

So if you cast 'ghost' while on the physical plane, then people, cameras, mages, what ever coudlnt see you (this would include manifested spirits).

However, things on the astral (projecting or even percieving mages, non-manifested spirits, etc) would still see the:
1) 'aura of the person (they are totally uneffected by a spell on the 'physical' plane)
2) the aura of the 'spell'


Now if you cast the spell while on the 'astral'. To those present in the astral your would be invisible. (and presumably if sustained, you would stay invisible even if you came back to the physical plane, however, the spell is 'astral' so can only effect those on the astrals.)

However to anyone on the physical plane you would be visible (since a spell cast on the astral can not effect them).

So to be 'completely' invisible.

1) Cast 'ghost' on yourself while on the physical plane.
2) Cast 'ghost' on yourself while astral.
3) Have Extended Masking and be atleat Initiate 2 (to block both spell aura's).

At this point to notice you.

Anything on the 'physical' would have to defeat #1
Anything on the 'astral' would have to defeat #2.

An initate (or something else that can peirce the masking) would have a chance to pierce the masking and possibly notice #3 (the spells)

I'm not planning to - I was merely pointing out that it would require both a physical and a mana version of the non-detection spell to implement laughingowl's plan to achieve total non-detectability.

1.) We are discussing variants on invisibility. Remove sense does work for some applications, but sure does tell every target that something is amiss.

2.) I´d make the spell itself invisible to the affected target for free. Otherwise it would end in one evil laugh and several attempts to hurt me.


You would not need two spells, as you can walk around dual natured without fear.

But a mana spell can not affect an unliving object (cameras) and a physical spell can not affect astral beings - so yes you would need two different spells.

I was wrong. I just thought that one spell to remove astral sight is enough and forgot about the technical angle.
