Engineer

Every machine needs an engineer to run it, and a living crew is no different. Engineers are the experts and professionals who rely on skill, bravery, and their tools to survive and keep others alive. While they do not claim to be fighters, their mere presence can turn the tide of battle or simply keep operations running.

BEHIND THE CURTAIN

While perhaps not as intimidating as a heavily-armored trooper, or as exotic as a lighsaber-wielding guardian, engineers are no less vital to group dynamic. They are armorers and gunsmiths, electricians and welders, or any other facet to be found in facilities across the galaxy. Their work, often unsung, is what keeps starships (and their crew) intact.

UNFLAPPABLE

It takes bravery for a soldier to enter a battlefield. It perhaps takes more for someone who is unarmed, and untrained in combat, to do the same. Engineers put their lives on the line for a living, whether by choice or acknowledging their plights as an occupational hazard. Whether they come from an elite training academy or learned their talents surviving in the slums, they are no strangers to danger and conflict.
While creating your engineer character, consider what your primary skill set is and how you use it. You could be a street-smart mechanic who taught yourself how to fix swoop bikes as a teenager. Perhaps you are the recent graduate of an esteemed medical college, or a rookie pilot in the fledgling Rebel Alliance. What is the number one skill you are known for? Why are you willing to enter battles when you have no combat training? How do you view the more adventurous members of your group, and how do they see you and your role?

QUICK BUILD

You can make an engineer quickly by following these suggestions. First, make Intelligence your highest ability score. Your next-highest score should be Constitution. Second, choose the scientist background.

TECHCASTING

Engineer: 1st level During your training you have derived powers from schematics with the aid of your wristpad. See chapter 10 for the general rules of techcasting and chapter 12 for the tech powers list.
Tech powers:

TECH POWERS KNOWN

You learn 3 tech powers of your choice, and you learn more at higher levels, as shown in the Tech Powers Known column of the engineer table. You may not learn a tech power of a level higher than your Max Power Level.

TECH POINTS

You have a number of tech points equal to your engineer level , as shown in the Tech Points column of the engineer table, + your Intelligence modifier. You use these tech points to cast tech powers. You regain all expended tech points when you finish a short or long rest.

MAX POWER LEVEL

Many tech powers can be overcharged, consuming more tech points to create a greater effect. You can overcharge these powers to a maximum level, which increases at higher levels, as shown in the Max Power Level column of the engineer table.
You may only cast tech powers at 6th, 7th, 8th, and 9th-level once. You regain the ability to do so after a long rest.

TECHCASTING ABILITY

Intelligence is your techcasting ability for your tech powers. You use your Intelligence whenever a power refers to your techcasting ability. Additionally, you use your Intelligence modifier when setting the saving throw DC for a tech power you cast and when making an attack roll with one.
Tech save DC = 8 + your proficiency bonus + your Intelligence modifier
Tech attack modifier = your proficiency bonus + your Intelligence modifier

TECHCASTING FOCUS

You use a wristpad (found in chapter 5) or the tools in which you are granted proficiency by this class as a tech focus for your tech powers.

POTENT APTITUDE

Engineer: 1st level Your technological experience lends you an uncommon insight that you can use to bolster your allies. To do so, you use a bonus action on your turn to choose one creature other than yourself within 60 feet of you who can hear you. That creature gains one Potent Aptitude die, a d4. This die changes as you gain engineer levels, as shown in the Potent Aptitude column of the engineer table.
Once within the next 10 minutes, the creature can roll the die and add the number rolled to one ability check, attack roll, or saving throw it makes. Once the Potent Aptitude die is rolled, it is lost.
A creature can have only one Potent Aptitude die at a time.
You can use this feature twice. You gain an additional use at 5th, 9th, 13th, and 17th level. You regain any expended uses when you finish a short or long rest.

INFUSE ITEM

Engineer: 2nd level You gain the ability to temporarily enhance a weapon or armor. At the end of a long rest, you can touch one unenhanced object that is a suit of armor, a shield, or a simple or martial weapon. Until the end of your next long rest or until you die, the object becomes an enhanced item, granting a +1 bonus to AC if it’s armor or a shield or a +1 bonus to attack and damage rolls if it’s a weapon.
Once you’ve used this feature, you can’t use it again until you finish a long rest.
This bonus increases to +2 at 10th level and +3 at 15th level.

Your gadgeteer harness is enhanced, requires attunement, can only be used by you, and counts as a tech focus for your tech powers while you are attuned to it. Your gadgeteer harness has 4 modification slots to which you can affix gadgets, and it gains more at higher levels, as shown in the Modification Slots column of the engineer table. For each modification installed in excess of your proficiency bonus, your tech point maximum is reduced by 1. Over the course of a long rest, you can install, replace, or remove a number of modifications up to your Intelligence modifier (minimum of one).
Some modification effects require saving throws. When you use such an effect from this class, the DC equals your tech save DC.

PROJECTED BARRIER

Gadgeteer Engineering: 3rd level As a bonus action while wearing your gadgeteer harness, you can expend a use of your Potent Aptitude to project a barrier on a friendly creature you can see within 30 feet. A creature can only have one barrier active at a time.

ENVIRONMENTAL BARRIER

You project an environmental barrier that lasts until the end of your next short or long rest. The barrier has a number of hit points equal to the amount rolled on your Potent Aptitude die + your engineer level. Whenever a creature with this barrier takes damage (one of acid, cold, fire, force, lightning, necrotic, poison, psychic, or sonic, chosen by you when you activate the effect), the barrier takes the damage instead. If this damage reduces the barrier to 0 hit points, the creature take any remaining damage.

PHYSICAL BARRIER

You project a physical barrier that lasts until the end of your next short or long rest. The barrier has a number of hit points equal to the amount rolled on your Potent Aptitude die + half your engineer level. Whenever a creature with this barrier takes damage (one of energy, ion, or kinetic, chosen by you when you activate the effect), the barrier takes the damage instead. If this damage reduces the barrier to 0 hit points, the creature take any remaining damage.

VERSATILE DIRECTION

Gadgeteer Engineering: 6th, 9th, 13th, and 17th level You can take a second bonus action on each of your turns. You can use this feature three times. You gain an additional use at 9th, 13th, and 17th level. You regain all expended uses when you finish a long rest.

REINFORCED BARRIERS

Gadgeteer Engineering: 14th level When you cast a tech power while you have a barrier active, you can restore hit points to the barrier, provided it is within 30 feet of you. You restore a number of hit points equal to twice the power’s level, or 1 hit point for an at-will power. This can’t increase a barrier’s hit points above its initial hit points. If you have multiple barriers active, you can divide these hit points between them as you see fit.

ADAPTIVE BARRIER

Gadgeteer Engineering: 18th level When a creature who has one of your barriers within 30 feet of you that you can see takes damage, and that damage is of a type that could be affected by that barrier, you can use your reaction to grant them resistance to the triggering damage. If that damage is the same type as the barrier’s chosen damage, you instead grant them immunity. Whether resistance or immunity, the barrier immediately drops to 0 hit points.

At the end of each of your turns, a deployed sentry automatically targets a hostile creature within 10 feet of it. If multiple targets are available, one is chosen at random. The target must make a Dexterity saving throw. On a failed save, it takes 1d4 energy damage and gains 1 slowed level until the end of your next turn. If a creature would be targeted by more than one of these sentries, it only makes this saving throw once, taking an additional d4 damage for each sentry beyond the first.

A creature struck by this attack is impaled by the hook. As an action, a creature can attempt to remove the hook. Removing the hook requires a Strength check. While the hook is stuck in the target, you are connected to the target by a 60 foot cable.
While the hook is deployed, you can use your bonus action to activate the reel, pulling yourself to the location if the target is your size or larger. A creature or object smaller than you is pulled to you. Alternatively, you can opt to release the cable (no action required).
Once you’ve used this feature, you can’t use it again until you recover and reinsert the hook as an action.

UNSTABLE ENGINEERING

Those engineers who choose the Unstable Engineering discipline create and use untested combinations, resulting in powerful�and often unpredictable�effects.

BONUS PROFICIENCIES

Unstable Engineering: 3rd level You gain proficiency in your choice of artisan’s implements. Additionally, when you engage in crafting with tinker’s implements, the rate at which you craft doubles.

MODIFIED TINKERCANNON

Unstable Engineering: 3rd, 9th, and 17th level You learn to enhance your tinker’s implements with unstable science, modifying them into a harness with a cannon. Over the course of a long rest, you can modify your tinker’s implements to create a tinkercannon. You must have tinker’s implements in order to perform this modification.
Whenever you cast a tech power of 1st level or higher while wielding your tinkercannon, you risk unexpected complications. Your GM can have you roll a d20. If you roll a 1, roll on the Unstable Engineering Surge table to create a random effect.
Additionally, your tinkercannon come equipped with four overrides, and they gain more at higher levels, as shown in the Modification Slots column of the engineer table. Each time you trigger an Unstable Engineering Surge, you can use an override to reroll the percentile dice. You must use the new result, you can only do this once per surge, and each time you do so in excess of your proficiency bonus (resetting on a long rest) your maximum tech points is reduced by 1 until you complete a long rest. You regain all expended overrides when you complete a long rest.

UNSTABLE VOLLEY

Unstable Engineering: 3rd, 9th, and 17th level While wielding your tinkercannon, as a bonus action you can expend one use of your Potent Aptitude to launch a volley of unstable energy at a surface located within 30 feet of you that you can see. This energy adheres to the surface for 1 minute, after which it erupts. As a part of this bonus action, or as a bonus action on a following turn, you can cause the energy to erupt early. Each creature within 5 feet of it must make a Dexterity saving throw against your tech save DC. A creature takes 1d6 lightning damage on a failed save, or half as much on a successfu one.
The range at which you can launch your volley increases to 60 feet at 9th level, and 120 feet at 17th level.
This damage increases when you reach certain levels in this class, increasing to 2d6 at 5th level, 3d6 at 11th level, and 4d6 at 17th level.

CREATIVE DESTRUCTION

Unstable Engineering: 6th level You can add your governing ability modifier (minimum of +1) to any damage you deal with tech powers and class features that don’t already include that modifier. If the tech power or class feature would damage multiple creatures, you can only deal this additional damage to one of them.
If you choose to deal this additional damage, your GM can have you roll on the Unstable Engineering Surge table.

EXPERIMENTAL OVERRIDES

Unstable Engineering: 14th level You gain a modicum of control over your surges. Whenever you roll on the Unstable Engineering Surge table and use one of your overrides, you can choose either total.

ENGINEERING BOMBARDMENT

Unstable Engineering: 18th level The harmful energies of your tech powers and class features intensify. When you roll damage for a tech power or class feature and roll the highest number possible on any of the dice, you can roll it again and use both results. You can only use this ability once per tech power or class feature.
