Choose another skill from the skill unit list. This is a class skill for your drone, which gains a number of ranks in that skill equal to your mechanic level. Your drone also increases its Intelligence score by 2. At 11th level, you can choose this mod a second time as an advanced mod. If you do, choose an additional skill to become a class skill for your drone (this skill doesn’t have to be on the skill unit list). Your drone gains ranks in the skill equal to your mechanic level. Your drone also increases its Intelligence score again by 2.

You understand how two skills work well together.

Choose one of the following skills: Acrobatics, Athletics, Computers, Engineering, Perception, or Stealth. This is a class skill for your drone, and it gains a number of ranks in the chosen skill equal to your class level. Your drone can use this skill when not under your direct control. You can change your drone’s skill unit whenever you rebuild your drone from scratch. Additionally, whenever you are directly controlling your drone, it can use any of your skill ranks if you wish, assuming it has the appropriate tools to do so (a drone without manipulator arms cannot use Engineering to disable a device, for example).

Humans gain an additional skill rank at 1st level and each level thereafter.

You can speak and read a number of bonus languages equal to your ranks in Culture. Additionally, when you attempt a Culture check to decipher writing, you can forgo your expertise die to attempt the check as a full action (rather than the normal 1 minute) per approximately 250 words of writing or fewer.

You can get the most out of flying technology.

When you attempt a Diplomacy check, you can choose not to roll your expertise die until later. After you determine what the check’s result would be, you can choose to either roll your expertise die and add it to the total or forgo the expertise die and reroll the check (see page 243). At 9th level, you can spend 1 Resolve Point to both reroll the check and add the result of your expertise die.

You leave fewer openings when making a ranged attack.

You know how to use small arms.

While you are wearing heavy armor or powered armor, you gain a +4 bonus to attack rolls to perform a bull rush combat maneuver (see page 246). If you successfully push the target back 10 feet or more, you can also damage the target with an unarmed attack (and can use your hammer fist ability when doing so).
