Confusion about Core:Confusion

[Jenceslav]

The Confusion spell in the Core lacks an Attack trait, which was errata-ed into Skull&Shackles and was probably printed in other instances of Confusion in the Class Decks.

And I am confused. Is this a new revision of the Confusion (with its broadened functionality), or is it an oversight? Does it apply for the older Confusion spells as well? If not, then we might be confused playing different Confusions.
So much Confusion, in every sentence :)

I suspect it's an oversight; see this post by Chad on how the Attack trait is modeled in PACG.

I will verify with Mike, but I'm fairly sure its absence is deliberate.

I guess design principles have changed over time. Makes sense - spells like Confusion I wouldn't bat an eye for a Summoner or an Alchemist using, for example, even if they list issues with using the Attack trait.

(I don't have a background in the RPG, mind.)
