DESCRIPTION

An observation trap extension allows you to modify the next trap you place in the same square to create a scrying sensor upon triggering.

You first place the observation trap extension as a saboteur trap in a square adjacent to you, just as you would any other saboteur trap. At any point within the next minute, you must place a second trap in that same square (either a saboteur trap or a mundane trap). This effect supersedes the normal rule that two saboteur traps cannot be placed in the same space. The observation trap extension merges with the second trap, enhancing its function. A trap that is enhanced by an observation trap extension notifies you mentally when it is triggered, similar to the mental alarm provided by an alarm spell but out to any range. You are not given any information about the triggering creature.

At any point within 10 minutes of receiving the alarm, you can choose to observe the creature that triggered the trap, as a scrying spell. The creature gets a Will saving throw against this effect (you are considered to have firsthand knowledge of the target, as described in the scrying spell). The scrying effect lasts for 1 minute per caster level.

The observation trap extension lasts until the trap is triggered, disarmed, or breaks apart (if the trap does so, as a saboteur trap does). Only one “trap extension” spell can be added to a particular trap.
