Class Features

Schematics Journal

As an aspiring gadgeteer you have a journal of schematics containing blueprints for simple mechanical designs and the first glimmerings of plans for things of a much more complex nature.   The schematics you add to your journal as you gain levels reflect the experimentation you conduct on your own as well as any intellectual breakthroughs. You might find other schematics during your adventures. You could discover a schematic recorded in the notes of a tinkerer, or in the organized library of an Engineer's Guild.  

Copying a Schematic into the Journal

When you find a schematic of Simple Complexity or higher, you can add it to your journal, if it is of a complexity for which you are able to produce and if you can spare the time to decipher and copy it. Copying a schematic into your journal involves reproducing the basic framework of the blueprint, then deciphering the unique system of notation used by the tinkerer who wrote it. You must make personal notes and drawings until you understand the intricacies of the design.   For each complexity of the schematic, the process takes 4 hours and costs 100 gp. The cost represents material components you expend as you experiment with the schematic to understand it.  

Replacing the Journal

You can copy a schematic from your own journal into another book. This is just like copying a new schematic into your journal, only faster and easier. You need only spend 2 hours and 20 gp for each complexity of the copied schematic.   If you lose your journal, you will be unable to create new gadgets or replace old ones. You must can use the same procedure to transcribe the schematics that you know into a new journal. However, since you are copying them from memory, it will take the same amount of time and resources as copying a new schematic.  

The Journal's Appearance

Your journal is a unique compilation of schematics, with its own style and margin notes. It might be a plain, functional notebook with neatly organized blueprints, an oversized portfolio with incredibly detailed notes, or a loose collection of illegible designs scribbled onto whatever paper on hand at the time.  

Gadget Schematics

You are skilled at building mechanical gadgets that perform various functions and incorporating them into your clothing, armor, weapons and other gear. Some gadgets provide a continuous benefit as long as the gadget is equipped (all unless noted by the DM). Other gadgets have an effect that requires you to take an action in order to activate it. Gadgets are built using schematics which show the design parameters and intended operation of the device. Each schematic has a level of complexity that is classified as Trivial, Simple, Advanced, and Intricate.   Gadget Slots per Complexity Level

Level	Schematics Known	Trivial	Simple	Advanced	Intricate
1st	2
2nd	3
3rd	6
4th	7
5th	9
6th	10

  At 1st level, you gain access to a limit of gadgets of your choice from the List of Schematics. The Schematics Known column of the above table shows when you learn additional gadget schematics. Any new gadget that you learn must be of a level which you are able to equip. A gadget lost or destroyed must be replaced entirely. Learning a schematic and turning the schematic into a working gadget costs an amount of money and time depending on the complexity. These costs include the parts and components needed to build the device as well the time spent prototyping, testing and troubleshooting the gadget to perfect its operation. The costs and time required for learning a new schematic are:  

Complexity Level	Cost
Trivial	10 gp/1 hr
Simple	40 gp/2 hrs
Advanced	250 gp/8 hrs
Intricate	1,250 gp/40 hrs

 

Equipping Gadgets

It takes time and effort to build and maintain your gadgets in working order. Repairs and preventive maintenance must be performed: sprockets greased, springs wound, etc. For this reason, you can only maintain a limited number of equipped gadgets, as shown in the Engineer Table. As you level up, you become more skilled at building and maintaining these gadgets, able to keep more of them functional at any time. Because of the expertise required to operate these gadgets and amount of personal customizations that each engineer makes to their gadgets, only the engineer that built it can use a gadget and benefit from its effects.
• Gadgets are somewhat "worn" like physical items. Each equipped gadget is integrated into one of your items of clothing as specified in the description. Multiple gadgets using different schematics each can be integrated into the same piece of equipment. Each integrated gadget increases the weight of the equipment by 2 lbs.
• You can equip gadgets, up to the maximum number shown in the Table. In order to equip a gadget, you must have an available gadget slot of the same or higher level of complexity as the schematic for the gadget.
• Whenever you complete a long rest you can reconfigure your list of active gadgets, changing which gadgets you have equipped from among the schematics that you know.  

Activating Gadgets

Some gadgets provide a continuous benefit as long as the gadget is equipped. Other gadgets have an effect that requires you to take an action in order to activate it. The type of action required to activate the effect will be listed in the description of the gadget.  

Object Interactions

Most gadgets are easy to activate, requiring you only to flip a switch or twist a dial. A gadget with an effect of this type can be activated at the same time you either move or take another action (such as an attack action). Some gadgets which can be used as weapons may require you take both an object interaction and an attack action at the same time. You can activate a second gadget effect that requires an object interaction on your turn by taking the Use an Object action. (See PHB pages 190 and 193 for more information about what sorts of actions can be combined with other actions.)  

Actions

A gadget effect with an activation time of 1 action requires that you focus your attention on the device in order to use it.  

Reactions

Some gadget effects can be activated as reactions. These effects are activated in response to some event. If a gadget can be activated as a reaction, the schematic description will tell you exactly when you can use it.  

Stacking Gadget Activations

You cannot activate two gadget effects that both require 1 action during the same turn. You can activate both a gadget that requires 1 action and another gadget that requires only an interaction by combining both activations into one action.

Gadget Attack Rolls and Saving Throws

Some gadgets can be used as weapons, allowing you to make an attack roll. The ability score bonus added to this attack roll is listed in the text for the schematic for that particular gadget. Your Intelligence modifier sets the DC for saving throws against effects created by the use of your gadgets.
• Gadget attack modifier = your Proficiency bonus + the ability score modifier listed in the gadget description
• Gadget save DC = 8 + your proficiency bonus + your Intelligence modifier  

Non-magical in Nature

Although some gadgets create effects which are similar to those created by certain spells and magic items, gadgets and their effects are inherently non-magical. A gadget, or the effect created by a gadget, cannot be detected or dispelled using abilities that work on magic. Spells such as Detect Magic, Dispel Magic, Counterspell, or Antimagic Field have no effect on the operation of a gadget.   Gadget Schematics can be found here...  

Overcharge

At 2nd level, you gain the ability to overcharge your mechanical devices and gadgets, augmenting their effects. You have 2 Charges and you gain more as you reach higher levels, as shown in the Charges column of the Engineer table. You can never have more Charges than shown on the table for your level. Many engineer features utilize Charges , denoting costs in such abilities' descriptions. The more powerful the Engineer, the more Charges you can invest into your gadgets and thus the more effective they can become. You regain 1d6 Charges during a short rest and fully regain them during a long rest.  

Engineer's Expertise

At 2nd level, choose two of your skill proficiencies, or one of your skill proficiencies and your proficiency with Tinker’s Tools. Your proficiency bonus is doubled for any ability check you make that uses the chosen proficiencies.  

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 Demolitionist
• Discipline of the Gadgeteer
• Discipline of the Kineticist
• Discipline of the Mechanist
• Discipline of the Technotheurge
(Each choice grants you different features at 7th, 10th, and 14th level.)  

Junkyard Hero

Beginning at 3rd 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 5 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.  

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.  

Mechanical Magic

Starting at 6th level, attacks made using your gadgets, constructs, or ticker bombs count as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.  

Academic Literacy

At the 8th level, you choose two Intelligence-based skills, or 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.  

Walking Encyclopedia

Starting at 11th level, you can add half your proficiency bonus, rounded down, to any Intelligence check you make that doesn’t already include your proficiency bonus.  

Gadget Mastery

At 16th level, when you roll a 1 on a damage die for a gadget you control, you may reroll that die. You must use the result of the new roll.   In addition, when you use a gadget that affects an area, you can shield some creatures in the area from being affected by the gadget. Choose a number of creatures equal to your Intelligence modifier minus 2 (minimum of 1 creature). The creatures that you chose are unaffected by the gadget  

Indomitable Mind

Beginning at 18th level, if your total for an Intelligence check is less than your Intelligence score, you can use that score in place of the total.  

Mechanical Mastery

At 20th level, you can draw Charges from your gadgets by rendering them temporarily inoperative. When you do so, you cannot use the chosen gadget or cannibalize it again and lose all of its benefits until the next time you take a long rest, and gain an amount of energy equal to its tier.
