Trap Finding

Rogues (and only Rogues) can use the Search skill to locate traps when the task has a Difficulty Class (DC) higher than 20. Finding a nonmagical trap has a DC of at least 20, or higher if it is well hidden. Finding a magic trap has a DC of 25 + the level of the spell used to create it.

Note that the second level cleric spell Find Traps can be used as well.

Rogues (and only Rogues) can use the Disable Device skill to disarm magic traps. Disabling a magic trap generally has a DC of 25 + the level of the spell used to create it.
