Baldur's Gate : The Sword Coast Chronicles : NWN2 Persistent World

As per d20srd data:
http://www.d20srd.org/srd/spells/nondetection.htm

Nondetection
Abjuration
Level: Rgr 4, Sor/Wiz 3, Trickery 3
Components: V, S, M
Casting Time: 1 standard action
Range: Touch
Target: Creature or object touched
Duration: 1 hour/level
Saving Throw: Will negates (harmless, object)
Spell Resistance: Yes (harmless, object)

I wouldn't mind. But I do have a cleric with the trickery domain.

Actually it would be a good thing for any cleric that has access to both trickery and illusion domains. You know, so that those two domains could actually support each other.

But I do not actually see the spell having much use beyond that to be honest.

This serves as an ammendment to the OP.
