Searching for a Spell...

[Crazy Cupcake]

Sorry to be a bother, but this is driving me barmy. I know there's a spell out there that can stop true seeing from thwarting illusions such as disguise self, but for the life of me I cannot remember the name of the spell or what book it's in. I was hoping someone could help me locate it.

I *think* it might have been one of the Forgotten Realms sourcebooks, and I remember that it took something like an hour or even a full day for the effect to kick in. But beyond that, I'm at a total loss.

Thanks in advance!

There is this thread? It mentions cloister, nondetection and sequester. Nondetection sounds like the closest spell.

The spell might be Cloak of Khyber (sor/wiz 3) from Dragon Magazine 337.

Must maintain a single form for 6 hours before you gain its benefits, which otherwise last for 1/day per CL or until you change forms again and must wait another 6 hours.

Cloak of Khyber, that was the spell I was thinking of. Thank you so much. :)

I could have sworn it was in a published book, though, not Dragon. Strange.

Edit: Found it! City of Stormreach, p. 59. :) Thanks again for the help!
