Engineer

By Marc Lee

"The shadowlander pulls a small metallic object from her belt and flick it toward the chieftain. As the object moves forward it unspools into a scourge made of sharp interlocked links of chain. The orc is no match for the whirling shadow. As the chieftain falls, the shadow flicks her wrist again and the weapon is once again safely and unobtrusively stowed on her belt. Now, time to find that treasure…"

"The gnome pulls his goggles down over his greasy hair to cover his eyes and presses a button on the back of his gauntlet. He feels the hot, acrid breath of the gigantic purple worm as the maw of the creature lunges hungrily down toward him. Steam shoots out of nozzles on the back of his boots. The wrenches and gears that adorn his outfit rattle and clank as he is propelled forward with a burst of speed, safely out of the creature’s grasp."

"The alley ends in a high stone wall – a dead end! The bandits round the corner and advance on him, certain that he has no way to escape. The gunslinger flips a lever on his belt as the bandits near him. In a flash, he disappears. The thugs freeze, looking confused, unsure where their prey has gone. The sound of a firearm round being chambered behind them is the last thing that they hear."

Though their motivations and tactics might be different, each of these engineers employs their superior skill with machinery and technology to overcome the various obstacles that stand between them and their goals. Their resourcefulness allows them to invent and build devices which help them enhance their abilities and augment their weaknesses.

Grab hold of Gadgets & Strange Technology

Not every scholar or inventor has the skills it takes to become an engineer. Engineers are not only students of science, but they are masters of turning scientific principles into new technology that has practical applications in the real world. Most have some education, though for many this education is the result of years of experimentation and tinkering rather than formal study. An engineer might be a member of a guild of like-minded craftspeople, or more likely, could simply be a self-taught loner with a talent for working with machinery. Engineers can do a little bit of everything. Whatever the challenge, they can invent, build, and adapt their gadgets to be the right tools for the job.

Mechanical Affinity

Masters of mechanical mayhem, engineers love to tinker with explosives, devices, and all manner of hazardous gadgets. They can take control of an area by placing turrets, support their allies with alchemic weaponry, or lay waste to foes with a wide array of mines, bombs, and grenades. Few engineers come from uncivilized lands, but that doesn’t mean that they are comfortable in social situations. In fact, many engineers find that mechanical devices make more sense than people. Clockworks and steam engines are infinitely more predictable than the average person could ever be. For this reason, engineers are sometimes seen as aloof or awkward, and some can even be downright abrasive.

Gadgets

At level 1, you gain access to 3 gadgets from the gadget list. If your DM requires it, acquiring a gadget costs money and time to craft, depending on the gadget's tier, as seen on the table below. While on your person, gadgets are always in effect. When you level up, you may choose to replace a gadget you possess and replace it with one gadget for which you meet the requirements. The old gadget is destroyed, and you must craft the new one. If a gadget is somehow damaged, you must repair it with an Intelligence (Tinker's tools) check with a DC=12+Gadget Tier, spending half of the cost and time to repair it. A gadget lost or destroyed must be replaced entirely. Many gadgets have spell-like effects, but these are nonmagical, and therefore cannot be affected by spells such as dispel magic, counterspell, or antimagic field.

Tier	Cost
1	25gp / 2 hours
2	40gp / 4 hours
3	75gp / 6 hours
4	150gp / 8 hours

The Gauntlet's barrier increases when you reach certain levels: 7th level (3d8), 13th level (4d8), and 19th level (5d8).

Elixir Grenade Gizmo (aka E.G.G.)

This backpack is actually a mobile chemical lab equipped with ingredients to make grenades on the move. The straps on the backpack contain a string of empty vials, which are passed to the interior of the bag and get injected by syringes of explosive chemicals. Creating a grenade counts as a bonus action, and throwing one count as a standard action. Each grenade is filled with a different substance capable of producing a wide variety of effects by reaching the target. Grenades can be thrown at a point of 20-feet away, and have a blast radius of 10-feet. Additionally, grenades can be launched by other means (per DM discretion).

• Elemental Grenade - For 2 Energy, creatures within the blast radius must succeed on a Dexterity saving through or receive 1d6 base damage on a failed save. For each additional Energy point spent, the damage increases by 1d6 (up to a maximum of 3 Energy points). Your elemental grenades can deal different types of damage:

• Acid - Any creature close enough to the impact, must also succeed a Dexterity saving throw or suffers poison damage equal to your Intelligence modifier until the start of your next turn.

• Cold - Creatures who fail a Dexterity saving throw suffer halved speed until the end of your next turn, unless they are immune to cold.

• Fire - Any creature in that area must succeed on a Dexterity saving throw or take 1d4 fire damage at the start of each turn.

• Lightning - Creatures who have half of their hit points or fewer and fail the Dexterity saving throw are stunned for 1 round.

The grenade's additional Energy limit increases when you reach certain levels: 7th level (4 energy), 13th level (5 Energy), and 19th level (6 Energy).

• Flash Powder - For 3 Energy, reach into your bag and pull out a vial filled with explosive flash powder. The vial explodes on impact, producing a bright flash. Each creature within the 10-feet blast radius of the point of impact must succeed on a Constitution saving throw or become blinded until the end of your next turn. The blast's radius increases when you reach certain levels: 7th level (15 feet), 13th level (20 feet), and 19th level (25 feet).

• Heavy Fume - For 3 Energy, you can create and throw up to three smoke grenades with a single action. Each fume grenade creates a cloud that lasts for 1d4 rounds and blinds creatures who attempt moving through it, upon starting their turn. The round limit increases when you reach certain levels: 7th level (2d4), 13th level (3d4), and 19th level (4d4).

• Double Throw - For 4 energy, two grenades can be created in a bonus action, and both can be thrown into a standard single action. Additionally, they can be thrown at different targets, at an additional thrown range of 5 feet. The additional range increases when you reach certain levels: 7th level (10 feet), 13th level (15 feet), and 19th level (20 feet).

Engineer Specialization

As an Engineer, you sometimes draw inspiration from different sources for your creations or inventions. At 3rd level, you begin to follow one field of study that defines your skills, typically trained in higher education:

• Discipline of the Battletech

• Discipline of the Gadgeteer

• Discipline of the Technotheurge

• Discipline of the Mechanist

(Each choice grants you different features at additional levels.)

Ability Score Improvement

When you reach 4th level, and again at 8th, 12th, 16th and 19th level, you can increase one ability score of your choice by (+2) points, or you can increase two ability scores of your choice by (+1) point. As normal, you can't increase an ability score above 20 using this feature.

Academic Literacy

At the 5th level, you choose two Intelligence-based skills. As an alternative, you could choose one intelligence-based skill and one set of tool that you're proficient in. Your proficiency bonus is doubled for any ability check you make that uses those chosen skills/tools proficiencies.

Junkyard Hero

Beginning at 9th level, you can use your downtime to scavenge spare parts, useful chemicals, and raw materials which you can use to build your gadgets or to craft items. In order to do so, you must be in a city, junkyard, or another location where such items can be found. Your DM may limit the availability of certain types of materials depending on the location where you are scavenging. For each hour that you spend scavenging, you can locate 1d4 gp + your level worth of such materials. You can use the resources you collect while scavenging to pay the material cost of learning new gadget schematics, creating or repairing, or as raw materials for crafting with tools with which you have proficiency.

Saboteur

Starting at 13th level, on each of your turns in and out of combat, you can make an attempt to disarm a trap or open a lock, using your Tinker’s Tools as a bonus action. Use this skill to disarm a trap, jam a lock (in either the open or closed position), or rig a wagon wheel to fall off. You can examine a fairly simple or fairly small mechanical device and disable it. The effort requires at least a simple tool of the appropriate sort (a pick, pry bar, saw, file, etc.). The DC depends on how tricky the device is. Disabling (or rigging or jamming) a fairly simple device has a DC of 10; more intricate and complex devices have higher DCs. If the check succeeds, you disable the device. If it fails by 4 or less, you have failed but can try again. If you fail by 5 or more, something goes wrong. If the device is a trap, you spring it. If you are attempting some sort of sabotage, you think the device is disabled, but it still works normally.

Crafting Expertise

Starting at 15th level, you are a master crafter, capable of producing excellent work under the budget on time, when you craft an item using tools that you have proficiency with, you make progress every day by spending crafting increments equal to 1d6 + your level in gp until you reach the market value of the item.

Discipline of the Battletech

Advanced Proficiency

At 3rd level, you gain proficiency with all Martial Weapons, Shields and Heavy Armor.

Power Suit

At 4th level, you believe that the biological and the mechanical can both be upgraded. You build a steam-powered mechanical armor, you call a Power Suit.

• The Power Suit functions as a Full Plate armor and augments your physical abilities to new levels. Your Signature Device and every new gadget schematics you create are assumed to be mechanical parts of the suit, for the purpose of overcoming the trouble of carrying the gear that would otherwise slow you down.

• Whenever you are targeted by an attack, you add your Intelligence modifier to your AC against all attacks made against you, for the rest of the encounter. The suit provides this bonus, even when caught flat-footed.

Mechanical Advantage

At 6th level, in your pursuit of combat superiority, you use a combination of devices to augment your Power Suit even further. For 1d6 Energy points, you deal bonus bludgeoning damage equal to you Strength modifier on melee attacks.

Volatile Evasion

Beginning at 9th level, you can nimbly dodge out of the way whenever an enemy, in your line of sight, subjects you to a certain effect that requires a saving throw. You instead take no damage if you succeed on the roll and only half damage if you fail. Additionally, you can draw a weapon on each of your turns in combat

Combat Energetics

Starting at 12th level, you thrive in the heat of combat. You have advantage on your initiative rolls. Whenever you land a successful hit with your Signature Device or a Gadget, you can perform an additional attack, as a bonus action.

Overcharge

At 20th level, your mastery of engineering enhances your Power Suit to live and breath for battle. For 1d10 Energy points, you can charge at your base speed and knock your target prone. You treat yourself as one size category larger for any rolls made during the charge. All attacks used in this way, gain the benefit of charging, including the equal amount of Energy to the attack roll. The movement limitations of a charge also apply. If you don't possess enough Energy, you consume the remaining Energy you have and performs the attack as such.

Discipline of the Technotheurge

"The Technotheurge has learned to maximize the energy source of the devices and manipulate them in various ways. They understand that magic is merely a form of science that has not yet been completely understood. Technotheurgists commit themselves to find objects or information through arcane means, in addition to using more conventional methods of study for both magic and technology and seek to integrate the two into a potent whole."

The N.O.V.A Gauntlet

At 3rd level, your knowledge of technotheurgic studies allows you to design a unique invention called the N.O.V.A. Gauntlet. This device can replicate the effects of various spells via arcane enhancements. Spell effects produced by the gauntlet are inherently considered to be non-magical, for the purposes of overcoming resistance and immunity. You can convert your Energy points to synthesize a spell of the corresponding level.

Note: N.O.V.A. = Not Officially Valid as Arcane'

• Distant Charge - When you cast a spell-effect from a distance, you can spend 1 Energy point to double the range of the spell.

• Empowered Charge - When you roll damage for a spell-effect, you can spend 2 Energy points to reroll and add your Intelligence modifier to the new result.

• Duration Charge - When you cast a spell-effect that has a duration of one round, you can spend 3 Energy points to double the effect's duration.

• Heightened Charge - When you cast a spell-effect that hits only one target, you can make the effect eligible and affect more targets equal to a number of Energy points spent.

Intricate Mind

Adaptive Bulwark

At the 17th level, once per day, when you are targeted by a spell that deals a type of damage (acid, cold, fire, lightning, thunder, sonic...etc.) you gain bonus resistance equal to your Intelligence modifier to that type of damage. You must complete a short or long rest to use this feature again.

Elite Technomancy

At level 20, your Intelligence score permanently increases by 2 points, to a maximum of 22.

Discipline of the Mechanist

Clockwork Knight

When you reach 3rd level, your fascination over clockwork mechanisms leads you to invent the most efficient and versatile construct: a Clockwork Knight. Creating a Clockwork Knight requires 4 hours of time and costs 100 gold worth of metal, rare threads, and other raw materials.

• Size Category: Medium Construct
• Weapons: Simple Melee Weapons & Shields
• Armor Class: 15
• Hit Points: 25 (+ 1d4 at each level)
• Speed: 30 ft.
• Languages: Understands the languages of its creator but can't speak.
• Challenge: 3/4
• Str 15 (+2) Dex 13 (+1) Con 15 (+2) Int 7 (-2) Wis 10 (+0) Cha 3 (-4)

The Clockwork Knight is a powerful fearsome construct to face in battle, that will fight to the death for its creator. In combat, the Clockwork Knight acts as your personal guardian. It's friendly to you and your companions and obeys any verbal commands that you issue to it (no action required by you). If you don't issue any commands to your Clockwork Knight, it protects you from hostile creatures. When a creature hostile to you moves within 10 feet of the Clockwork Knight on a turn or starts its turn there, it must succeed on a Dexterity saving throw. The creature receives 1d6 bludgeoning damage on a failed save, or half as much damage on a successful one. If the Clockwork Knight drops to 0 hit points it ceases to function. However, it can be repaired, but that will require half the time and cost of raw materials it took to build it.

Note: The Clockwork Knight doesn’t require air to breathe, food, drink, and sleep.

Conjure Mechanical Insect

At 5th level, you can create a mechanical device in the form of a tiny insect, such as a beetle, a cockroach, a butterfly or a cricket. Your new construct can fly, has 1 Hit Point and cannot attack. As an action on your turn, you can perceive through its senses, via a wireless communication up to 100 feet.

• Transmission: For the cost of 4 Energy, you can specify the device will travel for up to 24 hours toward any location which you have visited or the general description of a person. Upon arrival, it can deliver a message to the person that you have described, perfectly replicating the sound of your voice. If the Mechanical Insect is unable to locate the intended recipient within 24 hours, it gets destroyed. You can build a Mechanical Insect after a short or long rest.

Note: You can have only one Mechanical Insect at a time.

Continual Labor

At 10th level, you learn to craft and maintain an additional Clockwork Knight, following the same rules as the first.

Reconfiguration Upgrade

At 13th level, you learn how to apply efficient modifications to your creations. Determine one upgrade of the following list to a Clockwork Knight. That Clockwork Knight now has the function to transform into a new combat mode for the equivalent amount of Energy, as a bonus action on your turn.

Sentry Mode - For the cost of 6 Energy, the Clockwork Knight will transform into a deployable turret, to a space adjacent to you. Turrets are automated firearms used to defend and support the engineer and their allies. While in its Sentry Mode the construct cannot move from its position.

• Automated Strike - Enemy creatures that enter a 25-feet radius around the turret, or start their turn there, must make a Dexterity saving throw. On a failure, they suffer 1d4 + Intelligence modifier piercing damage. They take half the damage on a success. The piercing damage amount increases by 1d4 when at certain levels: 15th level (2d4), 17th level (3d4), and 19th level (4d4).

Gyro Mode - For the cost of 4 Energy, the Clockwork Knight will transform into a deployable flying drone. The drone has a flying speed of 30 feet, gets a +2 bonus on all Dexterity saving throws & Stealth checks, but cannot move more than 120 feet away from you.

• Aerial Guard - The drone, using heightened sensors to awareness of danger, can detect threats with ease. It has a +1d4 insight bonus on Perception checks, regardless of being caught flat-footed or struck by an invisible attacker, but loses the bonus if immobilized. This bonus increases by 1d4 when at certain levels: 15th level (2d4), 17th level (3d4), and 19th level (4d4). Enemy creatures within a 25-feet radius around the drone must succeed on a Dexterity saving throw. If it fails, the target becomes restrained by an integrated net launcher from the drone. The trapped creature cannot take any actions until it gets free.

Note: Only one type of Reconfiguration Upgrade may be deployed per Clockwork Knight. You can't have a Clockwork Knight with both Reconfiguration Upgrades.

Fast Activation

At 16th level, you learn how to modify any device as if you were holding it. This is not the same as telekinesis, but rather it allows you to simulate a device's functions. You are only able to access functions that a person using the device manually could access, and can only target one device at a time. Use a bonus action to execute the device-related task that would normally require an action.

Gearsmith Stallion

At 19th level, as an action, your Clockwork Knights can merge into a singular form. Your new construct takes the form of a mechanical warhorse that allows you to fight as a seamless unit. The Gearsmith Stallion always obeys your commands and serves you as a mount, both in Combat and out. While mounted on your steed, any ability you cast that targets only you, also target your steed. If it doesn't receive further directions from you, it preserves itself to the best of its ability. As an action on your turn, the Gearsmith Stallion can dismantle and re-build itself into two Clockwork Knights.

• Size Category: Large Construct
• Armor Class: 30
• Hit Points: 50 (+ 2d4 for each level)
• Speed: 60 ft.
• Languages: Understands the languages of its creator but can't speak.
• Challenge: 3/4
• Str 18 (+2) Dex 13 (+1) Con 17 (+2) Int 2 (+0) Wis 13 (+0) Cha 6 (-4)

Note: You can’t have more than one Gearsmith Stallion at a time.
