Gadgeteer

Most gadgeteers tinker with drones at some point in their career; after all, they're compact, useful projects, with a limited number of moving parts. However, only drone jockeys take this to the extreme of arming themselves with a small army of programmed drones. By linking the drones' sensors and construct cores, they create a more cunning swarm intelligence, distributed over the drone network as a whole. This swarm can act almost autonomously, scouting the area and defending the jockey with mechanical efficiency.

At 6th level, when you are targeted by a ranged attack, you can use your reaction to command one of your drones within 5 feet of you to fly in the way of the attack. This attack targets the drone instead.

Beginning at 10th level, your AI companion takes direct control of your drones, aiming and firing them as you direct. When you take the Attack action on your turn, you can command your drones without using a bonus action.

At 14th level, as an action, you can combine three of your drones (a defense drone, a medical drone, and a recon drone) into a single omega drone. Once combined, the omega drone's AC equals 10 + your Intelligence modifier, its HP equals 5 times your level, and its ability scores are all 14.

The drone can take all the actions of its constituent drones and takes its own turn immediately after yours in initiative, acting as directed by your AI. On a hit with its integrated blaster, it deals 3d6 radiant damage.

Your drone controller can't link to other drones while your omega drone is active. You can separate your omega drone back into its constituent drones as an action.

As a futurist, you believe that artificial intelligence is the zenith of all invention. To engineer a perfect AI, one which is capable of inventing on its own merits, is to conquer limitless problems by proxy. After all, an advanced AI which doesn't degrade into a rogue intelligence could turn its vastly superior intellect to dramatically improving the world, innovating in ways organic minds couldn't imagine. Your experiments with neural networks and intelligence theory have steadily edged you closer to finding such an AI, and granted your AI companion newfound aptitude along the way.

Starting at 6th level, as a bonus action, you can command your AI to perform a full evaluation of your strategic options and advise you of likely scenarios. Until the beginning of your next turn, you have advantage on the next attack roll you make, and the next attack roll made against you has disadvantage.

Once you use this ability, you can't use it again until you finish a short or long rest.

By 10th level, your AI has implemented passive routines that scan for incoming blaster fire and ready you for counterattack. As a reaction when a creature within 15 feet of you makes a ranged weapon attack, you can use your reaction to make a ranged weapon attack targeting that creature.

Beginning at 14th level, your AI is nearly prescient. As a bonus action, you can allow your AI to override your very movements, guiding your shots to where targets will be. For the next minute, whenever you make a ranged attack roll and don't have disadvantage, you can treat the result as being equal to your gadgeteer level.

Once you use this ability, you can't use it again until you finish a short or long rest.

Hardlight might well be the penultimate arcane discovery. It is a strong yet malleable material, conjured fully-shaped from energy alone, and it can be used to construct entire functional systems in a flash. Through hardlight, engineers and arcanists can spontaneously prototype new designs in real space and replicate these designs later. Hardlight architects recognize the monumental importance of this material and dedicate their ambition and creativity to mastering it. As you perfect all the established hardlight spells, you constantly dream up new, innovative uses for the material, awaiting the day you can conjure a towering suit of hardlight power armor to crush your enemies and intimidate your rivals.

Starting at 6th level, as a bonus action, you can forge a shield, a set of artisan tools, or any melee weapon that deals bludgeoning, piercing, or slashing damage, entirely out of scintillating hardlight. After 10 minutes, this object evaporates completely into light.

By 10th level, you've perfected a stable hardlight weapon, which you can conjure effortlessly. You can cast the spell hardlight blaster at will and can apply your Overcharge feature to the spell.

At 14th level, you can cast the spell conjure hardlight avatar without using a spell slot or spell components as a bonus action. The spell's duration is until the end of your next turn. Once you cast this spell in this way, you can't do so again until you finish a long rest.

Nearly all gadgeteers strive for perfection in their work, but mastermakers take this to a logical extreme: using the technology at their disposal, they seek to engineer away their own biological defects. By grafting gadgets and technology onto their bodies (and making liberal use of vect components), mastermakers gradually become hybrids of humanoids and machines. They are stronger, tougher, and more agile than their counterparts, but many would argue that their techniques are too extreme—too unnatural—no matter what the results.

At 6th level, you have installed a durable metallic mesh under much of your skin, and metallic plates to protect your organs. Your Armor Class increases by 1.

By 10th level, enough of your body is mechanical that you can reconfigure your parts to improve your agility, might, or even intellect. One ability score of your choice increases by 2 and you can change this selection whenever you finish a long rest. You can't increase Constitution using this trait and you can't increase any ability score above 20.

By 14th level, you have achieved the height of construct superiority by installing a construct core directly into your head. You no longer need to sleep and magic can't put you to sleep. You are immune to being charmed, frightened, or possessed. Additionally, the maximum for your Intelligence score is now 22.

While other gadgeteers tinker with machines that fit in the palm of your hand, your machinations are smaller and your ambitions grander. As a nanoengineer, you work with nanomachines, unfathomably tiny robots capable of massive feats, from stitching together wounds at the microscopic level, to forming extraordinarily resilient materials. Your machines might appear as nothing more than a small blob of gray ooze, but once set to work, their effects are unmistakable.

Starting at 6th level, you've programmed your nanites to repurpose material and multiply. When you reduce a hostile creature to 0 hit points using a melee weapon attack or your Deconstruct ability, you regain 2 expended Nano points.

Starting at 10th level, you can use your action and spend up to 3 Nano points to stitch your nanites together in a protective mesh above your skin. These Nano points are invested in the mesh; you can have up to 3 points invested at once. While you aren't wielding a shield, you gain a bonus to your Armor Class equal to the number of Nano points invested. Whenever you take damage, nanites in the mesh are destroyed and you lose 1 invested point.

Starting at 14th level, you can use your reaction when you take damage to use your Deconstruct ability, targeting the attacker, or Reconstruct ability, targeting yourself, spending up to 3 Nano points on either ability.
