Technician Core Class: Engineer

The Engineer

The Engineer uses intelligence to resolve non-magical issues with technology and finds inventive solutions to problems. They use a variety of technologies to deal with enemies. The Engineer does not use any magic to achieve their goals, eschewing its usage in favor of reliable, practical approaches that are not influenced by the inherent instability of magic on Dunia.
Because of this difference in focus, they are more durable than the Arcanist or Inscriptor. They can be essential in terms of vehicle maintenance and improvements, or offer a lot of other utility options with crafting. Intelligence is the main driver of their ability to hit, but also for success with inventions. The Engineer does, however, require materials to be useful.

Subclass Overview

Chemist

The Chemist is the Alchemist of Dustriders. They can formulate various concoctions with available materials and can craft ammunition, explosive weapons, and chemical weaponry. They are also capable of making drugs, stimulants, narcotics, medicine, poison, and painkillers. A chemist adds a bit of explosive energy to a party.

Mechanic

The mechanic can take just about anything that has a motor and make it run well. Their focus isn't in combat but in enabling others to win fights through combat as a support subclass. The mechanic can use just about any makeshift weapon, drive any vehicle, and use any turret. The mechanic is highly trained in repairs and can identify issues with vehicles more quickly than other subclasses. The mechanic can also weld armor to a vehicle or repair broken components. A dip into the Mechanic subclass can be hugely beneficial to any party in Dustriders.

Roboticist

The Roboticist uses machinery in combat offensively and defensively to turn the tide of battle. They craft drones, turrets, mobile cover, and can augment party members' armor substantially. In some ways, they play the role of a summoner with none of the issues arising from magic being used in the MEZ.

Features

1st Level

Engineering Precision
As an Engineer, your insightful observations are your greatest strength. You can choose to expend 1 Precision Point when making any ability check or saving throw to add a bonus equal to your Proficiency Bonus to that roll, regardless if you are Proficient in that ability or save.
The number of precision points you have is 1 per level plus your Intelligence modifier. You can recover all of your Precision Points during a short or long rest. Sometimes a nap is all you need for that spark of genius.
Resourceful Ingenuity
As an Engineer, you are incredibly resourceful with your available materials. On any attempt to craft, repair, or modify, roll 1D4 in addition to any checks or actions you make to see if you can save resources and/or components. This changes to a 1D6 at 6th level, a 1D8 at 10th level, and a 1D12 at 14th level in the Engineer class, thereby increasing the chances of cutting back on resource costs. This does not apply to reassembling a disassembled item.
You cannot reduce an item's material or component cost to 0 for any of its parts when crafting, but you can reduce a material cost for repairs to 0.
Additionally, the Engineer normally only uses half the time to create items by default.
Rolling a 1: you save no additional resources while crafting or repairing.
Rolling a 2: you save up to a quarter of your resources used while crafting or repairing. You cannot reduce a cost to 0.
Rolling a 3: you save up to half of your resources used while crafting or repairing. You cannot reduce a cost to 0.
Rolling a 4 or higher: you succeed in using up only one of each material or component listed in the schematic's crafting requirements, or spend 0 materials or components when making a repair.
Crafting Materials Reference
Schematics Analysis
As an Engineer, you can read schematics to learn how to build the item, vehicle, or weapon described in the schematic. When analyzing a schematic, it must be done during or after a Long Rest. This requires Investigation checks against a challenge rating of DC10 + the schematic's Rarity level. The rarity of the schematic determines how many investigation checks are required (up to DM discretion), and each check can only be done once during or after a long rest.
As an example with the normal rules, a Very Rare schematic would require passing a DC 14 Investigation check check a total of 4 times, over however many Long Rests it takes to succeed 4 times.
At 1st Level in Engineer, you get a free choice of two Common schematics. Each level up after 1st in the Engineer class, you learn a new schematic for any item, vehicle, or weapon of your choosing, as long as it is a rarity you can craft. To determine the available schematic rarities, see the Engineer's feature table.
The rarity of the schematics you can learn from analysis or gain from leveling goes up at set intervals. You can learn Common schematics at 1st level as an Engineer. Uncommon starts at 6th level, Rare starts at 11th level, Very Rare starts at 17th level in this class.
Disassembly Analysis
You can obtain a Baseline quality schematic from any item you have disassembled, regardless of rarity. Disassembled items will yield the same amount of resources as are required to craft them, so you can put them back together.
Disassembly time depends on the size of the equipment, item, or vehicle.
For a weapon or item, the amount of time to disassemble and gain a schematic is a number of Long Rests multiplied by the rarity. As an example, a Common rarity Armanov D-74 will take 1 Long Rest to disassemble and analyze, but a Very Rare MP-01 SMG will take 4 Long Rests. This is to emulate the added complexity of higher rarity items and difficulty in replicating the manufacturing processes.
Once you have disassembled the item and analyzed it successfully, you may reassemble the item at the end of the activity without using additional time. Reassembled items cannot benefit from the Resourceful Ingenuity feature's materials cost reduction.
For a vehicle, the salvage times equal the disassembly time.
Drafting and Learning Schematics
Each time you level up, you learn a new schematic of your choice, of a rarity that you can learn. When you learn the chosen schematic, you gain a copy of said schematic. This schematic cannot be completely destroyed as you retain its blueprints in your mind. You may only learn Exotic schematics where specified.
As an Engineer, you can draft schematics. This allows them to be revised, shared, and improved. As long as you have paper and pencil, you can draft. Drafting consumes one piece of paper, and only takes a Short Rest to make a copy of it.
Drafted schematics go into your inventory inside a portfolio, which can be any shape of your choosing. You can share drafted schematics with other engineers, which they can analyze to copy the shared schematic.
You may also share schematics with other people, and they may use the schematic to craft or assemble an item or weapon.
Salvaging Items and Vehicles There are three states of viable salvage for each item or vehicle part which determine how many components and materials can be obtained through scrapping or salvaging. The type of the item or vehicle being broken down also comes into play. The GM can roll or arbitrate the status of the different parts on the vehicle being salvaged.
Good: The item or part can be scrapped for the full materials, with 75% or more remaining HP for the scrap for it to be considered in Good Condition
Moderate: The item or part can be scrapped for half the materials from its crafting requirements listed on the item's or vehicle's page, with between 25-75% remaining HP for the item or part it to be considered in Moderate Condition
Poor: The part might be able to be scrapped for a quarter of the materials from its crafting requirements listed on the item's or vehicle's page, with less than 25% remaining HP for for the item or part it to be considered in Poor Condition
Destroyed: Cannot be scrapped.
Saving Throws
Enemies that must make a saving throw against your abilities or other checks must pass your Engineering DC.
The Engineering DC is calculated as follows: 8 + Intelligence Modifier + Proficiency Bonus = Engineering DC.

2nd Level

Weaponized Precision (Attack)
Your knowledge is your weapon. When you make any attack roll with a weapon you can expend a Precision Point to strike your opponent where it will really hurt. Add your intelligence modifier to your attack rolls and damage by expending a Precision Point.

3rd Level

Archetype Features
Exotic Baseline Schematic
Choose a Exotic type, Common rarity, Baseline quality schematic in addition to any other schematics you are learning during this level-up.
Signature Schematics
Dependent on the archetype chosen, you will learn three Improved Quality schematics. These will become your Signature schematics. You can have three Signature schematics at a time. If you want to change out your Signature Schematic, it must be during a level up and from your subclass' schematics list.
They will automatically get enhanced when you learn to draft Advanced Quality and Masterwork Quality schematics. Improved is essentially a +1 version of an item. Advanced is a +2 version of an item. Masterwork is a +3 version.
When you reach the following levels in the Engineer class, you may select three new schematics, choosing one from each category granted by your chosen archetype.

6th Level: Uncommon

5th Level

Extra Attack
Starting at 5th level, you can attack twice instead of once whenever you take the Attack action on your turn.
Improved Schematics
You can improve existing schematics to the Improved quality starting at 5th level. If you have drafted a schematic either through learning it or finding one, you can make an Intelligence roll to improve that schematic against a DC11 check. You can try this improvement once per day. Failures only mean that you need to perform this check again the next day.
This will make the schematic better in a chosen attribute or equivalent to a +1 version of the baseline variant. Improved armors gain an additional utility mod slot and have a +1 to their Evasion bonus over baseline.
Improved Revisions
Starting at 5th level, you can now enhance any existing crafted items and schematics to their Improved versions. Your Signature crafted items, if they weren't already Improved versions, are enhanced to an Improved version for free. To enhance an existing item you have crafted to an Improved version, you must spend the equivalent of a Long Rest or 8 hours and make an Intelligence roll against a DC11 check. If you fail, you may try again the next day. If you succeed, you enhance the item.

6th Level

Exotic Improved Schematic
Choose an Exotic type, Uncommon rarity, Improved quality schematic in addition to any schematics you are learning during this level-up.
Smart Scrounger
Starting at 6th level, you obtain the full amount of resources when scrapping items, equipment, or vehicles, as long as it is not destroyed. Scrapping items usually do not yield the same amount of resources that disassembling an item would but takes much less time. When you scrap an item, you do not learn its schematic.
Uncommon Schematics
Starting at 6th level as an Engineer, you may learn Uncommon schematics at this level, and each time you level up.
Additionally, choose one new schematic from each category of your chosen Archetype's signature schematics to learn at this level.
For example, if you chose a Chemist, choose one new Uncommon schematic from each of the three following categories: Explosive Devices, Medical Devices, and Drugs. Effectively, you would be granted a new Uncommon explosive schematic, a new Uncommon medical device schematic, and a new Uncommon drug schematic.

Mobile Chemical Factory
You may now synthesize mundane chemical materials during a short rest or downtime, at a rate of 2 mundane chemical materials per hour. Additionally you can combine two existing chemical materials of one rarity to a higher rarity. This can be done during a short or long rest, or using up to one hour of downtime. If performed during a long rest, you combine a number of chemicals equal to the hours rested.
Chemthrower
You may now craft a Chemthrower, which allows you to load a canister with an elemental effect into a flamethrower-like device. This Chemthrower has a slightly lower range than a normal Flamethrower. This counts as one of your devices and can be augmented in the same way as other Chemist devices.
Each of the ammunition types have a different effect and requires a Dexterity saving throw against your Engineering DC. The Chemthrower also allows you to choose which shape the attack is made in by adjusting the nozzle as a free action.
Attacking with the Chemthrower counts as an attack.
The crafting requirements for the Chemthrower are as follows.

1 Mundane Electronics component

2 Mundane Glass components
