Your drone gains one of the following feats as a bonus feat (it must meet all the prerequisites of the chosen feat): Advanced Melee Weapon Proficiency, Basic Melee Weapon Proficiency, Heavy Weapon Proficiency, Longarm Proficiency, Small Arm Proficiency, or Special Weapon Proficiency. You can select this mod multiple times; each time, your drone gains another of the available proficiency feats as a bonus feat.

You can affix a small arm or another one-handed ranged weapon on your drone, allowing it to wield that weapon and attack with it. This weapon cannot be disarmed. Mounting a longarm, a heavy weapon, or another two-handed ranged weapon requires two weapon mounts. A weapon mount can hold up to two batteries, two magazines, or two of another type of ammunition for the affixed weapon, provided this ammunition is of light bulk or less. Multiple weapon mounts used to affix a single two-handed weapon count as a single weapon mount for the purpose of how much ammunition it can hold. The drone reloads these batteries or magazines automatically, which takes the usual amount of time for the weapon. Spent batteries or magazines are stored within the drone. You can replace all of a weapon mount’s batteries or magazines as a move action. You must purchase separately or already have the weapon and ammunition for use with a weapon mount. You can replace the weapon with any other weapon that meets the criteria for your mount (for example, if you have two weapon mounts, you could replace a longarm with a heavy weapon). Swapping out a weapon in a weapon mount requires use of your custom rig and 1 hour of work. You can select this mod multiple times, each time adding an additional weapon mount to the drone.

Your drone is outfitted with cargo space. The drone’s Strength score counts as 4 higher for the purpose of how determining much bulk it can carry, but all of this extra bulk must be stored gear and cargo, not mounted weapons, armor mods, or the like. This does not affect the drone’s actual Strength score in any way, merely how much it can carry. Due to its size, a drone might still be unable to carry awkward or unwieldy items.

Your exocortex provides you with enhanced combat ability, granting you proficiency with heavy armor and longarms. At 3rd level, you gain weapon specialization in longarms just as if your class granted proficiency. As a move action during combat, you can designate a foe for your exocortex to track. As long as that target is in sight, the exocortex feeds you telemetry, vulnerabilities, and combat tactics, allowing you to make attacks against that target as if your base attack bonus from your mechanic levels were equal to your mechanic level. Designating another target causes you to immediately lose this bonus against the previous target.

You can use your exocortex’s memory module to enhance your own knowledge. Once per day, as a reaction while not in combat, you can reroll a failed skill check (see page 243) to recall knowledge (see page 143). In addition, your exocortex grants you the Skill Focus feat as a bonus feat. You can’t use your exocortex’s memory module while combat tracking is activated. Every time you gain a mechanic level, you can rebuild your exocortex’s memory module, replacing the exocortex’s bonus Skill Focus feat with Skill Focus in a different skill.

You construct an artificial intelligence (or AI), a sophisticated program of self-motivated code that you can access for help in a variety of endeavors. This AI is the product of your own genius, far more advanced and complicated than any available for sale to consumers (though it falls short of being truly self-aware), and only you know the secrets of its creation and operation. Your AI can take one of two forms: a drone or an exocortex. You must pick one of these forms upon taking your first level of mechanic, and once this choice is made, it cannot be changed.

Drone

You begin play with a powerful robotic drone to house your AI. You build and control this drone, which accompanies you on your adventures and is capable of combat, espionage, and other specialized tasks. As you gain levels, your drone advances in sophistication and gain additional abilities. While the value of your drone is immense, only you, with your extensive knowledge of its quirks and security measures, can ever hope to operate or repair it.

Exocortex

You begin play with an exocortex, an artificial processor that interacts with and augments your biological brain’s cognitive functions, which can aid you in a variety of tasks, from combat to digital infiltration. Your exocortex is implanted within your physical body or brain, similar to a piece of cybernetic hardware, allowing your AI to access your mind and feed you information. As you gain levels, your exocortex advances in sophistication and processing power. Only you can access or interact with your exocortex.

You are skilled at getting inside computer systems and electronic devices. At 1st level, you gain a +1 insight bonus to Computers and Engineering skill checks. At 5th level, every 4 levels thereafter, and at 20th level, this bonus increases by 1.

You have created a customized toolkit you can use to hack systems and items. Your custom rig can be configured to take up an upgrade slot on your armor or can be installed as a cybernetic augmentation system in your brain (though it can be combined with a datajack for the same price as installing a datajack normally), your eyes, or an arm. For more information, see augmentations. Alternatively, you can configure it to be a handheld device, meaning that you must retrieve it and hold it to use it effectively. While using this rig, you always count as having the appropriate tool or basic kit for any Computers or Engineering skill check you attempt. Some mechanic tricks and drone mods require the use of a custom rig. In addition, you can use your custom rig as a Mk I comm unit. Finally, if you have a drone, you can use your custom rig to communicate over an encrypted channel with your drone to issue commands to its AI or directly control it at a range of 2,500 feet.

If your custom rig is damaged, destroyed, lost, or stolen, you can kitbash a new one from any engineering kit, hacking kit, or other technological toolkit, reconfiguring the materials into a new custom rig with 1 hour of work. You can have only one custom rig at a time. If you create a new custom rig, your old one functions as a normal toolkit of whatever type you made it from and can no longer be used with your mechanic tricks.

When one of your mind-affecting charm or compulsion spells or spell-like abilities ends, the target loses all memory that it was magically controlled or influenced. That creature still remembers the actions it took, but may be confused by them.

You gain the channel skill ability at 1st level (instead of 2nd level). Each day when you recover your spell slots, you can tap into the Akashic Record, enabling you to choose one Profession skill and add that to your list of associated skills for the channel skill class feature.
