Thanks,<br/><br/>The trap is very dependent on what the others may have at hand. The only thing that she has herself that may be of use is something that might alert the party that the door has been opened while they are on the way out... but if someone has something like alchemist fire or so on, she's not opposed to setting a fire trap. Holy water works well too. ;)<br/><br/>So, unless otherwise offered, she'll probably jamm the lock so that it can't be unlocked from the inside and be done with it... assuming that that damage could be repaired if they come back. Something like jamming the mechanism with a dagger, for example.
