Drone Mods

As you gain levels, your drone gains custom modifications, gear, and programming that give it additional capabilities and options. Any level-based abilities for your drone’s mods use your full mechanic level, regardless of whether you’re using control net to assign fewer levels to your drone.
Your drone gains its first custom modification at 1st level and an additional mod every 2 levels thereafter. Mods are grouped into two categories, basic and advanced. You can choose basic mods at any level, but you must be 11th level (or have assigned at least 11 levels to your drone) to select advanced mods. Some mods require your drone to have other custom mods installed before they can function. Unless otherwise noted, each mod can be selected only once.

Basic Mods

You can choose these mods at any level.

Armor Slot (Ex) [LINK]

Starfinder Core Rulebook p.77

Your drone gains an armor upgrade slot for an armor upgrade. If you do not already have an armor upgrade to install, you must purchase one separately. You can install the armor upgrade only if your drone has enough open upgrade slots to meet the upgrade's requirements. You can select this mod up to four times, each time adding an additional slot.


Barricade (Ex) [LINK]

Starfinder Armory p.147

Your drone gains the Barricade feat. Your drone must have Engineering as a class skill and manipulator arms for you to select this mod.


Camera (Ex) [LINK]

Starfinder Core Rulebook p.77

Your drone has a camera that you can see through using your custom rig as long as your drone is within range. The camera has ordinary sight, and is capable of seeing whatever an ordinary human could see. The camera can also record up to 1 hour of footage, which can be downloaded and viewed using your custom rig.


Cargo Rack (Ex) [LINK]

Starfinder Core Rulebook p.77

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.


Climbing Claws (Ex) [LINK]

Starfinder Core Rulebook p.77

Your drone gains a climb speed equal to half its land speed. This mod can be applied to only combat and stealth drones.


Cybernetic Bridge (Ex) [LINK]

Starfinder Armory p.147

Your drone can be improved with one cybernetic (Core Rulebook 208) or magitech (see page 90) augmentation, selected from only one of the following systems: arm, brain, ears, eyes, hand, legs, or throat. If the augmentation has an item level that is 4 or more levels lower than your ranks in Engineering (for cybernetics augmentations) or Mysticism (for magitech augmentations), you can create and install the augmentation yourself at no cost. You can change such self-built augmentations once per day with 1 hour of work. If the augmentation is not 4 or more levels lower than your appropriate skill ranks, you must acquire and pay for the augmentation (including changing or replacing the augmentation) normally.


Enhanced Armor (Ex) [LINK]

Starfinder Core Rulebook p.77

Your drone gains a +2 bonus to its AC. At 11th level, you can choose this mod a second time as an advanced mod.


Enhanced Senses (Ex) [LINK]

Starfinder Core Rulebook p.77

Your drone gains low-light vision, darkvision to 60 feet, and a +2 insight bonus to Perception skill checks. If your drone has the camera mod, the camera gains these senses as well.


Extra Ammo (Ex) [LINK]

Starfinder Core Rulebook p.77

One of your drone's weapon mounts can hold two additional batteries, magazines, or other type of ammunition in addition to its usual weapon and ammunition capacity. Your drone must have the weapon mount mod before selecting this mod. You can select this mod more than once, up to the number of weapon mounts the drone has.


Grease (Ex) [LINK]

Starfinder Armory p.147

Your drone can dispense grease on itself or an adjacent object or area as a standard action. This functions as the spell grease (DC = 11 + your drone’s Dexterity modifier) but is not a magic effect. Once your drone has used this ability, it cannot do so again until you take a 10-minute rest and spend 1 Resolve to regain Stamina Points while you have access to your drone.


Hardened AI (Ex) [LINK]

Starfinder Core Rulebook p.77

Your drone's AI is secured against outside influence. Any attempt to hack your drone takes a -4 penalty, and your drone receives a +4 insight bonus to saving throws against spells or effects that attempt to take control of the drone or otherwise dictate its actions.


Heuristic Programming (Ex) [LINK]

Starfinder Armory p.147

Your drone can learn from its mistakes. When it fails a skill check, and attempts the same skill check for the same task the next round, on its second attempt it may roll the check twice and take the better of the two results. Once your drone has used this ability, it cannot use it again until you take ten minutes to review its programming. You may do this at the same time you take ten minutes and spend 1 Resolve Point to regain all your Stamina Points.


Hydrojets (Ex) [LINK]

Starfinder Core Rulebook p.77

Your drone is equipped with miniature marine jet engines, granting it a swim speed equal to half its land speed. This mod can be applied to only combat drones and stealth drones.


Jump Jets (Ex) [LINK]

Starfinder Core Rulebook p.77

Your drone is equipped with powerful miniature jets. It can use these jets to jump up to 30 feet as a move action (either vertically, horizontally, or in any combination that does not exceed 30 feet). If applied to a hover drone, these jets instead allow your drone to increase its fly speed by 30 feet for 1 round. Once used, these jets must cool down for 1 minute before they can be used again.


Manipulator Arms (Ex) [LINK]

Starfinder Core Rulebook p.77

Your drone is equipped with two robotic arms with simple hands. They can perform most functions that your arms can perform (such as opening doors, typing on a keypad, wielding a weapon, or attempting skill checks that require manual dexterity), but attacks made with them take a -4 penalty.


Melee Weapon Arm (Ex) [LINK]

Starfinder Core Rulebook p.77

Your drone is equipped with a robotic arm to which you can affix a one-handed melee weapon, allowing your drone to wield that weapon and attack with it. This weapon cannot be disarmed. Wielding a two-handed melee weapon requires two melee weapon arms. If you do not already have a weapon to equip, you must purchase it separately. Swapping out a weapon in a melee weapon arm requires use of your custom rig and 1 hour of work. You can select this mod multiple times, each time adding an additional melee weapon arm to the drone.


Resistance (Ex) [LINK]

Starfinder Core Rulebook p.77

Your drone gains resistance to an energy type of your choice-acid, cold, electricity, fire, or sonic-equal to your mechanic level, to a maximum of 10. You can select this mod multiple times. Its effects do not stack; each time you select this mod, it must apply to a different energy type from the list above.


Riding Saddle (Ex) [LINK]

Starfinder Core Rulebook p.77

Your drone is equipped with a seat and programming to carry a rider as a combat-trained mount. If you ride your drone, it must be at least your size or larger. To carry another rider, the drone must be at least one size larger than the rider. You can direct your drone mount in battle without attempting Survival checks.


Skill Subroutines (Ex) [LINK]

Starfinder Core Rulebook p.78

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.


Smuggler's Compartment (Ex) [LINK]

Starfinder Core Rulebook p.78

Your drone has a secret compartment that can hold a single item of light bulk or smaller. A successful Perception check (DC = 15 + your mechanic level) is needed to notice or find the compartment. Accessing this compartment is a move action.


Speed (Ex) [LINK]

Starfinder Core Rulebook p.78

Your drone's land speed increases by 10 feet.


Tool Arm (Ex) [LINK]

Starfinder Core Rulebook p.78

Select one technological item no more than light bulk and an item level no higher than your mechanic level. Your drone is equipped with a robotic arm with that item attached and the proper programming to use the item, although it cannot use a tool that requires skill checks unless it also has ranks in the relevant skill (or you have ranks in the relevant skill and the drone is under your direct control).


Weapon Mount (Ex) [LINK]

Starfinder Core Rulebook p.78

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.


Weapon Proficiency (Ex) [LINK]

Starfinder Core Rulebook p.78

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.


Advanced Mods

You must be 11th level or higher to choose these mods.

Echolocators (Ex) [LINK]

Starfinder Core Rulebook p.78

Your drone uses basic echolocation to notice unseen foes. The drone gains the blindsense (sound) ability.


Energy Shield (Ex) [LINK]

Starfinder Core Rulebook p.78

Your drone gains an energy shield that provides it with a number of temporary Hit Points equal to your mechanic level. This shield remains active until all of its temporary Hit Points are depleted. The drone can replenish the shield's Hit Points to full by spending 1 Resolve Point when you rest to regain Stamina Points. You can select this mod a second time to double the energy shield's temporary Hit Points.


Excavator (Ex) [LINK]

Starfinder Core Rulebook p.78

Your drone gains a burrow speed equal to half its land speed. It can use this speed to move through clay, dirt, earth, and sand. It does not leave a hole behind, nor is its passage marked on the surface.


Flight System (Ex) [LINK]

Starfinder Core Rulebook p.78

Your drone gains a fly speed equal to half its land speed with average maneuverability for up to 10 minutes per day. This duration need not be continuous, but it must be used in 1-minute increments. You can select this mod a second time; in this case, the drone's fly speed increases to its full land speed, and there is no limit on the amount of time it can fly.


Greater Resistance (Ex) [LINK]

Starfinder Core Rulebook p.78

Choose one type of energy for which your drone already has the resistance mod. Increase your drone's resistance to that energy type by 5. You can select this mod multiple times. Its effects do not stack. Each time you select this mod, it applies to a different energy type for which your drone has the resistance mod.


Invisibility Field (Ex) [LINK]

Starfinder Core Rulebook p.78

Once per day as a standard action, your drone can turn invisible for 10 minutes, as per the invisibility spell. If it makes an attack during this time, the invisibility ends. Your drone can spend 2 Resolve Points to use this ability again on the same day. Your drone must have the reactive camouflage mod to select this.


Medical Subroutine (Ex) [LINK]

Starfinder Core Rulebook p.78

Your drone is equipped with first aid capabilities. If you are reduced to 0 Hit Points, your drone can attempt to administer emergency medical treatment to you, even despite you being unconscious. On subsequent rounds on your turn, your drone takes as many move actions as necessary to return to your side, followed by a standard action to administer first aid. Once it has done so, you can spend 2 Resolve Points to recover a number of Hit Points equal to your mechanic level. Your drone cannot use this mod on anyone but you nor use it if you are dead or have fewer than 2 RP remaining. You can't benefit from this treatment more than once every 24 hours. Your drone must have the manipulator arms and skill subroutines (with the Medicine skill) mods to select this mod.


Reactive Camouflage (Ex) [LINK]

Starfinder Core Rulebook p.79

Your drone is equipped with a thin coating that can change color to match the drone's surroundings. Whenever your drone stays stationary for 1 round, it gains a +10 bonus to Stealth checks (this bonus doesn't stack with the invisibility spell or similar effects). If your drone takes any action, it loses this bonus until it once again spends 1 round remaining still.


Reductive Plating (Ex) [LINK]

Starfinder Core Rulebook p.79

Your drone gains damage reduction 1/-. This increases to DR 2/- at 7th level and increases by 1 again at 13th level and every 3 levels thereafter.


Shock Wave (Ex) [LINK]

Starfinder Core Rulebook p.78

Whenever your drone is reduced to fewer than 10 HP, it immediately shuts down and unleashes a shock wave of electricity as a reaction (even if it is deactivated or destroyed by the attack). This deals 1d6 electricity damage per level to every creature within 10 feet (except the drone). An affected creature can attempt a Reflex save to take half damage (DC = 10 + half your mechanic level + your Intelligence modifier).
