It would seem that if an Astral Invisibility spell (Mana naturally) was developed (or rediscovered) and a person had both Invisibility and Astral Invisibility cast on them (so that dual natured creatures couldn't sense them with either sense.) then they would be covered. And the Astral Invisibility would keep any one failing to resist from also seeing the spell auras. Why, because Mana based illusions affect the mind.

And while in SR4A it says " Illusions cannot fool assensing to disguise or create auras.", we know initiates can mask their auras.

And in Digital Grimoire, False Impression and Manascape can at least disguise an aura.

Yep. Just like Mask won't make you invisible, it would just make you look like someone else.


Uh, what? Take a moment to catch your breath and read what people are saying, rather than reading into what they're saying and trying to alter it to what you want them to be saying. It might help a bit.


From what I see you're saying, not really. Manascape is just "Mass False Impressions." It won't be able to mask its own aura, only preexisting auras in its area of effect.

I think your biggest problem is that you're not quite getting that this is a limitation of Sorcery, not Magic. Those are two separate things. Sorcery cannot be used to remove an aura, especially a spell's own aura, but there might be a metamagic technique, critter power, or some other means of doing so down the road. False Impressions is already a borderline spell, but that's not surprising since most of Digital Grimoire is a hodgepodge of random nonsense, wretchedly written rules, and inconsistency anyway. Don't cling to it like it's actual gospel or a wonderful place to draw proof of concepts from.

If you really insist on introducing something like this in your game, lean towards making it an advanced metamagic technique that keys off of Masking and Extended Masking as prerequisites. And even then, be very careful about how you approach it. Oh, and be sure you're sufficiently powerful to defend yourself once word of your development gets out. Every megacorporation and powerful magician the world round will likely be hunting you down to learn its secrets.

OK two threads here after we settled the Invisibility (M) does not hide you on the Astral plane because the spell aura gives you away.

One was would an Astral Invisibility spell if it existed conceal the spell's own aura. Purely an academic question.


This lead to False Impression and Manascape and would their aura's be exposed or concealed.
I thought that Manascape had no problem since it is an area effect illusion spell. Most substained Illusions can be adjusted by the caster after they have been casted.

So at least with Manascape once the spell is active, the caster can blend the spell aura in to other auras to hide it.

And if that is the cause why limit False Impression so much that no one would take it when they could have Manascape instead.

I thought False Impression was one of the better spells balanced spells in Digital Grimoire.
Also while they are both certainly useful, I don't think they measure up to the metamagic abiliites like Masking and Extended Masking.
It is nice to have some rare lore like that to dangle in front of the PC spellcaster

The answer is that those spells don't work by RAW as illusion spells can't disguise or create auras.
