To whom it may concern: While I was waiting around invisible at a merchant my aishan did the script where it guards me. The problem is that the aishan thus revealed that I was in the room by doing so.

So... could a trap be put in there for invisible (and hiding, probably) status that it either doesn't do that script or that it guards "something" without giving away who (my preference is the former)?

I don't know which other demons might have scripts which can do this but stealthy demonologists beware - forewarned is forearmed.

(whispered aside) She's a she. ;-)
