OOC: Disable Device is not a skill that Jillian can take 10 or 20 on.
OOC: I just wanted to clarify. I understand why she can't take 20 on the check because if she fails by 5 or more the trap goes off. But the only stipulation for taking 10 is that the character not be threatened or distracted. The only skill that explicitly prohibits the use of taking 10 is the Use Magic Device skill. Are you thinking that when a rogue is trying to disarm a trap that she is threatened or distracted by that trap at that moment? If it is a DM ruling that is fine. Also in rereading the text for the Disable Device skill it states, "Your DM makes the Disable Device check for you secretly...".
OOC: Okay, I think you are correct. You can take ten, at some risk. Otherwise I will be happy to make the rolls.
OOC: Scott DeWar, you said that Harrison read the "riddles and warnings" out loud, but you didn't post the contents for us to see. Was this some cruel joke?
