====== ENGINEERING ======

You can identify, build, repair, or disable technological devices;
assess the stability of structures and machinery. 

If you don’t have an engineering kit when attempting an Engineering check, you take a –5 penalty to the check.


===== Assess Stability =====

You can use Engineering to assess a structure or a piece of
machinery to determine its stability, usability, and structural
weak points. This takes 1 minute or more, and the DC is
determined by the GM.

Use the following base DCs for Engineering checks to assess
stability. These DCs can be adjusted by other circumstances
such as the complexity of the structure and damage to the
structure, as determined by the GM.

^TASK^ DC^
|Assess stability| 15|
|Determine structural weak point| 20|
^CIRCUMSTANCE^DC MODIFIER^
|Simple structure (rope bridge or unstable ceiling)| –5|
|Complex structure (suspension bridge or space station wall)|+5|
|Obvious damage| –5|
|Slight but consequential damage| +5|
|Intentional sabotage| +10|

=====Diagnose a mechanical device=====
You can diagnose mechanical devices either with the help of built in diagnostics or manually. You need a toolkit for the manual diagnostics.

^Situation^ DC^ Time Required^
|Simple basic checks(is the oil filled, is there gas..)|7| 1 minute|
|Run a diagnostics on an advanced system|12| 2 rounds but diagnostics may take a lot more|
|Manually diagnose a mechanical system|17| 10 minutes|


=====Craft mechanical device=====
You can use Engineering to create mechanical devices from parts.  See the [[crafting]] rules for details.

=====Identify mechanical device=====
You can use Electronics to identify the properties and uses of
technological items and devices such as vehicles or weapons,
as well as alien things. Generally, a check is not required to
identify relatively simple technological items that are commonly
available. You can take 20 on an Engineering check to identify
technology, but only if you have a means of researching, such
as access to an information network or downloaded data set.

The DCs for Engineering checks to identify technology are
based on the item’s rarity.

^ITEM RARITY^ DC^
|Common, complex technology|5 + 1.5 × item’s level|
|Less common technology|10 + 1.5 × item’s level|
|Rare, ancient, or alien tech| 15 + 1.5 × item’s level|

=====Repair technical device=====

You can use Electronics to repair a technical device, 
as long you have access to it. The amount of time this takes typically depends on the
complexity of the object. You can repair an object or piece of
equipment you crafted in half the usual time. The DC of the
check is determined by the GM and based on the complexity of
the object and how broken it is. If you succeed, you restore a number of Hit Points
equal to the result of your Engineering check or remove one negative condition from it. 
If you fail the check by 10 or more, you damage the object further, dealing
1d4 damage to it.

The above hitpoint changes are doubled for huge or larger objects and halved for diminutive or smaller objects.

If the object or piece of equipment is damaged but not
broken, you can repair it at a cost of 1% of it's value. If it is broken but not
destroyed, you must spend parts equal to half the damage % of the item each time you
attempt to repair it. A destroyed object or piece of equipment
can’t be repaired with the Engineering skill, though of course you can craft a new.

You can’t take 20 on an Engineering check to repair an item
or object.

The DC for an Engineering check to repair an item is based
on the complexity of the object. The following chart provides
base DCs by complexity and examples of such items. The GM
may adjust these DCs and times to reflect other circumstances.

^ITEM EXAMPLE^ TIME^ DC^
|Simple thing like a wall |10 minutes| 15|
|A Car|30 minutes| 20|
|Most complex things like weapons or armor| 1 hour| 15+1.5×item’s level|

=====Arm/Disarm Bomb=====
You can use engineering to set and defuse mechanically fused bombs. Note that actual manufacturing of bombs is not included, though it is possible to craft a bomb using engineering rules in [[crafting]] from explosives.

^Situation^ DC^ Time Required^
|Activate a bomb or mine| 10| Usually 1d3 rounds|
|Shut down a simple bomb|15| Usually 1d6 rounds|

A booby trapped or sensor protected bomb must first have it's sensors disabled with [[electronics]] or it will go off on the disarm attempt. Note that this definitely applies to most mines.

=====Bypass mechanical locks=====
You can use engineering to bypass mechanical locks. A failure will automatically set of any connected alarms.

Note that in some cases you can also bypass electronic locks with engineering by doing a physical bypass, however such bypass will almost always trigger any alarm

^Situation^ DC^ Time Required^
|Simple lock|20|1 round|
|Average lock| 25| 1 round|
|Good lock| 30| 1 round|
|Superior lock| 40|1 round|

=====Bypass traps=====
You can use engineering to bypass mechanical traps.

^Situation^ DC^ Time Required^
|Simple system|20|1 round|
|Average system| 25| 1 round|
|Good system| 30| 1 round|
|Superior system| 40|1 round|


=====Disable mechanical device=====
You can use engineering to disabling things, from jamming doors to draining the fuel from things.

^DEVICE^ EXAMPLE^ TIME^ DC^
|Simple device| Jam a door| 1 round*| 10|
|Tricky| Device Sabotage a simple propulsion system|1d4 rounds|15|
|Difficult device|  | 2d4 rounds|20|
|Complex device|  |2d4 rounds|25|
|Equipment| Disable an armor upgrade, powered armor, or a weapon |2d4 rounds| 15 +1.5 ×item’s level|

* Note that some very simple devices can take longer to disable, like welding a hatch shut might take a minute, but are no harder to do.

=====Make traps=====
Engineering can be used to turn technical things into traps and to construct mechanical traps.  Hiding those traps requires use of [[Stealth]] or [[Survival]] skill normally depending on the situation.
