Invisible Illusion

[A Mite Excessive]

Can you make an illusion invisible, to like, fool someone with see invisible?

[Starglim]

A figment fools the minds of others, creating a false sensation. I don't think you can create a sensation that others can't .. sense. If the figment affects multiple senses, you can choose not to create a visual effect, but then there's nothing to see, despite see invisible.

Its effect is not a creature or object, so technically it's not a valid target for invisibility.

A figment detectable only by someone using See Invisibility sounds like a perfect candidate for spell research. I don't believe that 'see invisibility' is a sense mentioned by any of the existing spells in the silent image line, for example.

[Starglim]

Oh sure, something along the lines of phantom trap and magic aura.

[Ascalaphus]

As a custom spell, sure. The whole theme of "fooling special senses" has been developed a lot in Heroes of the Darklands by the way.

With a regular Silent Image, nope. Invisible things aren't visual illusions, by definition.

Yesterday upon the stair, I saw a man who wasn't there, he wasn't there again today - I wish, I wish he'd go away ...
