You are skilled at disarming traps and opening locks. In addition, this skill lets you sabotage simple mechanical devices, such as catapults, wagon wheels, and doors.
Editor's Note: In the table below we have attempted to organize the various tasks, DCs, and required actions/time to attempt in one table. If information is missing (such as the Take 10/20 columns) it simply means that the answer was unclear to d20pfsrd.com editors at this time. Consult the Core Rulebook or other official sources for more information.)
1 If you attempt to leave behind no trace of your tampering, add 5 to the DC.
When disarming a trap or other device, the Disable Device check is made secretly, so that you don’t necessarily know whether you’ve succeeded.
The DC depends on how tricky the device is. Disabling (or rigging or jamming) a fairly simple device has a DC of 10; more intricate and complex devices have higher DCs.
If the check succeeds, you disable the device. If it fails by 4 or less, you have failed but can try again. If you fail by 5 or more, something goes wrong. If the device is a trap, you spring it. If you’re attempting some sort of sabotage, you think the device is disabled, but it still works normally.
Special A rogue who beats a trap's DC by 10 or more can study the trap, figure out how it works, and bypass it (along with her companions) without disarming it.
Retry? You can retry checks made to disable traps if you miss the check by 4 or less, though you must be aware that you fail in order to try again.
You also can rig simple devices such as saddles or wagon wheels to work normally for a while and then fail or fall off some time later (usually after 1d4 rounds or minutes of use
The DC to open a lock depends on the lock's quality: simple (DC 20), average (DC 25), good (DC 30), or superior (DC 40).
Modifiers: If you do not have a set of thieves’ tools, these DCs increase by 10.
Retry? Yes. You can retry checks made to open locks.
The amount of time needed to make a Disable Device check depends on the task:
The spells fire trap, glyph of warding, symbol, and teleportation circle also create traps that a rogue can disarm with a successful Disable Device check. Spike growth and spike stones, however, create magic traps against which Disable Device checks do not succeed. See the individual spell descriptions for details.
About This Section Optionally, a character who reaches 5, 10, 15, or 20 ranks in a skill unlocks various bonuses and abilities unique to that skill. The unchained rogue uses these rules extensively, but others can gain access to them with a new feat.
In this system, characters unlock additional abilities when they attain 5, 10, 15, and 20 ranks in a skill. The skill unlocks system interfaces with the unchained rogue to make the rogue the true master of skills.
Skill unlocks give characters new abilities and ways to use their skills upon reaching 5, 10, 15, and 20 ranks in a skill. Any character with the Signature Skill feat can earn skill unlocks for a single skill, and they are a prime feature of the revised version of the rogue who uses her rogue's edge ability to gain skill unlocks for several of her most iconic skills. Alternatively, you might make skill unlocks a universal part of the game, but you should be aware they add significant power and flexibility to skills, so giving them for free to all classes would grant power boosts to other highly skilled classes such as the investigator and bard, particularly in comparison to the rogue. Another alternative is to eliminate access to the Signature Skill feat, limiting skill unlocks to rogues and rogues alone.
With sufficient ranks in Disable Device, you earn the following.
5 Ranks: Reduce the time required to disarm a trap or open a lock by taking a –5 penalty on your Disable Device check for each step by which you reduce the time required: 2d4 rounds, 1d4 rounds, 1 round, a standard action, a move action, a swift action.
10 Ranks: You can disarm magical traps at a –10 penalty even if you lack the trapfinding ability. If you possess the trapfinding ability, when attempting to disable magic traps, you never trigger them, even if you perform the trigger action (such as looking at a symbol). If you fail the check, you can still trigger the trap, and you can't use this ability to bypass it.
15 Ranks: When attacked by a trap, you can attempt a Disable Device check as an immediate action (adding your trap sense bonus, if any) opposed by the trap's attack roll or its save DC. If you succeed, you take half damage (or no damage if you exceed the DC by at least 10).
20 Ranks: You halve the penalties for performing a quick disarm as described in the 5 Ranks entry. If you possess the trapfinding ability and accept a –20 penalty while using the ability unlocked at 15 ranks, all nearby allies gain the benefit, and you disable the trap as an immediate action before it can trigger if you exceed the DC by at least 10.
Special: A character can take 10 when using Disable Device to arm or disarm explosives, but cannot take 20.
Time: Arming an explosive device takes 1 minute or more, depending on the scope of the job. Disarming an explosive is treated as if the explosive were a complex trap, and takes 2d4 rounds to attempt.
