My group has had some discussion over the use of Scan and Search and we would appreciate other people's opinions.
Question 1) Do people use passive Scan and Search or are those skills only attempted when the player declares their adventurer to be using them?
i.e. If the adventurers are about to step onto a trap or walk into an ambush, do you allow them to attempt a roll to detect it before it is activated even if the players haven't requested one?
Question 2) If so, which skill? Walking into an ambush would seem like a situation appropriate for Scan, but if it is a tripwire or pit trap, would you use Scan or Search?
Question 3) If a passive use of the skill is allowed, do the adventurers get to use the skill at:
Full skill?
Half Skill?
Require a Special success to succeed?
Some other amount?
Thanks heaps people.
