Chapter 10 - Experiments

Experiments are projects that engineers do to create technological devices. An experiment occurs generally during an Engineer or Scientist's down time and they can be as simple as writing a program, or as complicated as constructing a dreadnought cruiser. To perform an experiment, you need the correct plans that is often record by some means, sometimes scroll, other times datapad. Plans contain one or more rituals that you can use as often and as many times as you like, as long as you can spare the time and have the components to undergo the project.

An experimental plan contains (scroll, or data file), contains a single experiment, and you can perform the project from that plan. Anyone can use these plans to perform the project, as long as the appropriate materials are expended. This chapter explains the following:

Acquiring and Mastering an Experiment All about datapads and scrolls, how you acquire them, and how you master a project.

Performing an Experiment: How to perform an experiment, whether from a data pad or scroll.

How to Read an Experiment: The specifics on how to understand an experiment's description and effects.

Experiment Descriptions: Descriptions of a wide variety of experiments, from construction projects to mad scientist rituals.

Acquiring And Mastering an Experiment

Before you can perform an experiment, you need to acquire plans that contain the steps in detail.

Acquiring a Data-pad

You can buy a Data-pad or find them as treasure. These are simple computer notebooks that are mostly a touch screen tablet and are used mostly as a viewer. Allowing the user to view, or write experimental projects on the tablet's surface. On these of these devices there are two universal bus port allowing the device to be plugged to more powerful computers. You can also make a copy of existing files and transfer them to your data pad.

Buying an Experiment Datapad: You can buy a data-pad at any computer store for 50 gp. An experiment datapad has 128 peta-bytes. Each experiment takes up 1 peta-byte. An experiment takes up a number of peta-bytes equal to it’s level. The description of each experiment gives its market price, which is the gold coins cost for a datapad containing the experiment or the cost to add the new experiential to your existing datapad computer (if there's enough room in it).

Finding an Experiment Datapad: When you explore during your adventures, you might discover files, blueprints, or even datapads that contain projects. Such items are part of the treasure you qcquire while adventuring.

Creating a Experiment File: You can create a new experiment file copying project files from existing datapad to your own. You can store higher level experiments on your datapad if you wished as well. In addition copying an experiment file from another datapad is simple. All it requires is the time it takes to transfer it from one datapad to the next. Since the files are so big and complex transferring them generally takes 30 minutes per level of the experiment. Computers with upgrade bonuses can lessen the transfer time by 30 minutes for each bonus.

Mastering an Experiment

Owning an experiment datapad isn’t enough to let you perform the experiment in it. You must first master the experiment by studying it for 8 uninterrupted hours. (If you gained a experiment by creating its file yourself or by obtaining it as a class feature, you have already mastered it.)

You must meet two requirements to master an experiment. You must have the Experiment Project feat (Engineer Adept get this at 1st level), and your level must equal or exceed the experiment's level. If you meet those requirements and spend 8 hours studying an experiment, you can add it to your list of mastered experiments. As long as you have the datapad handy, you can perform a mastered experiment whenever you want.

There’s no limit to the number of experiments you can master.

Acquiring a Experiment Scroll

An experiment scroll is a roll of blueprints, vellum, or paper.

Buying a Experiment scroll: Like a data pads, an experiment scroll can be purchased for the given market price.

Creating a Experiment Scroll: You can create a experiment scroll by transcribing an experiment you have mastered. Creating an experiment scroll takes twice the amount of time as creating it on a datapad but costs the same price.

Limitation: Even though an experiment scroll lets you perform an experiment, you can neither master an experiment from a scroll nor copy a scroll into your datapad. An Experiment Scroll is a condensed version of an experiment, made with short hand notes, and directions to perform a specific experiment.

Conducting an Experimental Project.

To conduct an experimental project that you have mastered, you spend a certain amount of time

To perform an experimental project that you have mastered, you spend a certain amount of time (specified in the experiment description) performing various actions appropriate to the experiment. The actions might include tinkering, heavy construction, crafting, or combining chemicals. The specific steps required aren't described in most experiment descriptions; they're left to your imagination.

An experiment requires certain components, which you purchase or harvest before you being the project and which are expended when the project is complete. Each experiment specifies the cost of the materializes you need.

If an experiment requires a skill check, the check usually determines the experiment's effectiveness. Even if the check result is low, an experiment usually succeeds, but if the result is high, you can usually achieve better effects. In addition low results can lead to flaws in your crafts.

Assisting in an Experiment

Unless an experiment specifies otherwise, up to four of your allies can help you perform an experiment. Everyone assisting you must be within 5 squares of you, and each assistant must actively participate in the experiment for the entire time required to complete it. Your assistants need neither the Ritual Caster feat nor knowledge of the specific ritual.

Your allies can assist you in two ways. First, if the experiment additional hands to complete the work necessary to finish the project they can fill the rolls and be directed by you and your blueprints. This helps a great deal since you don't have to hire out to additional hands! Second, your allies can assist with the skill check you make to complete an experiment, using the normal rules for cooperating on another character's skill check.

Interrupting an Experiment

At any time before a experiment is completed, you can stop it and suffer no ill effect. Depending on the nature of the project will determine if you have wasted your materials or not (Dungeon Master's will make this determination). You can resume an experiment at any time

Using an Experiment Scroll

An experiment scroll holds one use of a particular experiment. You can perform a scroll’s experiment even if you don’t have the Experimental Project feat, regardless of the level of the experiment. You still have to expend the components and supply any focus required by the experiment, and you can enlist your allies’ assistance. However there are limitation, as some experiments require specific skills that you might not have and success can't be possible.

How to Read an Experiment

Experiments are described in a consistent format, the elements of which are outlined below.

Name a Flavor Text

Beneath an experiment's name is a short passage of flavor text that tells what an experiment accomplishes, sometimes expressing that information in terms of what the experment will look like upon completion.


Each experiment has a level. You have to be level or higher to perform the experiment from a datapad.


An experiment is classified in one or more categories, which describe the experiment’s general nature and function. Each of the six experiment categories is associated with one or more skills (given in parentheses in the following list).

Engineering Experiments: (Engineering, Technology, Science: Chemistry, Science: Physics, Science: Mathamatics)

Mechanical Experiments: (Mechanics, Science: Physical)

Biological Experiments: (Science: Biology, Science: Chemistry)

Computer Engineering: (Use Computer, Technology)

Cybernetics Experiments: (Engineering, Technology)

Behavioral Experiments: (Science: Behavioral)


This entry shows how long an experiment will take to be completed.

Material Cost

This is the value of the materials that must be expended to complete an experiment

• Engineering Parts (Engineering): Typically these are specific parts for the project at hand. They can vary in size, and shape and cost.

• Technology Parts (Technology): Typically electromechanical parts, for example, transistors, computer chips, and so on, or computer parts.

• Mechanical Parts (Mechanics): Typically mechanical parts are gears, engine parts, moving parts in machinery.

• Chemical Supplies (Science: Chemistry): These are chemical supplies that are used to mix, or to be used with a specific purpose of the experimental project.

• Physic Supplies (Science: Physics): These are physics supplies that are used in a specific experimental project.

• Biological Supplies (Science: Biology): These are equipment such as microscopes or biologcal chemicals like blood, glyoclouse, and supplies needed to do experiments with biology.

You can buy materials at some shops, your allies can provide them (sharing the cost of an experiment with you), or you might find them as treasure. However you acquire materials, record their value on your character sheet. When you perform an experiment, mark off the experiment cost from the appropriate materials.

Some experiment's descriptions note other costs, or specific items that are essential to the experimental project (such as specific systems for starships, or leg parts for a robot, and so on). These parts are explained in detail in other sections.

Market Price

This entry is the cost to purchase a datapad containing the ritual. A scroll containing an experiment costs the same amount.
Key Skill

An experiment's key skill determines the type of materials required to perform the experiment, and if a ritual requires a skill check, the key skill is used for the check. If this entry ends with “(no check),” then the experiment does not require a skill check.

If an experiment has more than one key skill, you choose which skill to use. Your choice determines both the materials you use and the skill you use for any checks required by the experiment.

Unless a experiment’s description says otherwise, you make your skill check when you finish performing an experiment. You can’t take 10 on one of these skill checks.


The text that follows the foregoing information describes what happens when you finish an experimental project.

Experiment's Descriptions

The experiment's descriptions use the words “character” and “creature” interchangeably.
