Finally we hit the character creation chapter of the book!

Now that we’ve gone over the mechanics of play, it’s time for us to put together a character in Star Trek Adventures, learn how Supporting Characters work, and how Character Development is handled mechanically.

Needless to say, this is a huge article of nearly 3000 words, so I’m putting it all behind the jump.

Now that we’ve already had a chance to check out the setting and the purpose of Starfleet in Star Trek Adventures, let’s move on to the discussion of the game side of the equation with a look at the mechanics.


This section is the primer for the most basic concepts of the game. Star Trek Adventures runs off the 2d20 system, which uses 2 kinds of dice: 20-sided and six-sided dice. The d20’s are used to determine successes, while the d6’s are used mainly to determine effect or to roll on tables.

Like in other 2d20 games, the d6’s are also called something else to denote their use when determining damage. Called Challenge Dice in Star Trek, rolling a six-sided die is read according to the following table:

Bit of a typo on the title of the table there.

So, when rolling 6 Challenge Dice to determine damage, and you end up with a roll of: 3,5,1,4,1,2 then that means you score 5, plus 1 Effect (from the 5). Effects can be used to trigger all sorts of things, but are most common in triggering Weapon qualities.

To make life a little easier Modiphius sells challenge dice with blank sides and special notation to show Effects. Plus they look really spiffy.

Basic Operations

Moving on, we get to discuss some basic concepts of the Star Trek Adventure RPG:

Scenes and Encounters

Scenes are the first thing introduced in this section. Pretty appropriate given that the game is supposed to approximate the nature of the TV shows, scenes are a pretty vague slice of time where the characters interact in a way that has a significant impact to the plot. The players and the GMs are encouraged to gloss over the “boring” stuff and cut from scene to scene to keep the pace nice and punchy.

Encounters are defined as a special type of scene where a conflict between two or more parties is broken down into rounds and turns. Combat is the most common example of an Encounter.


Traits are a concept that will be familiar to gamers who have played games like Fate. Similar to Fate’s Aspects, Traits are single word or short phrases that describe a single significant fact about the subject that the Trait pertains to.

That said I’m much more partial to the Traits as they deal in objective facts as opposed to a phrase that can be re-interpreted in various ways.

Star Trek Adventures gives four rough categories of Traits:

  • Situation Traits are traits that state a fact about a (usually) temporary condition that affects a scene. Darkness is cited as an example.
  • Location Traits are traits that define the nature of a location that the characters currently occupy. Klingon Technology would be an example of a Location Trait if a team were trying to escape from inside a Bird of Prey.
  • Personal Traits are traits that apply to a given creature, and denote some innate quality. Human, or Vulcan are both examples of Personal Traits.
  • Equipment Traits describe a single piece of equipment and are in effect for as long as the character has it. This means, of course that the Trait can be passed on to a different character if they hand the equipment over.

But why are traits so important? Traits also help establish the Truth of a setting in three ways:

  1. The Trait has no effect on the tasks being performed and is solely descriptive.
  2. The Trait is beneficial, and can enable an action that would normally be impossible, or reduce its difficulty. These Traits are also known as Advantages.
  3. The Trait is detrimental, and can prevent an activity from being performed, or increase its difficulty. These Traits are also called Complications.

One last thing about Traits that it’s possible for particularly powerful Traits to count as multiple versions of itself. The book uses Subspace Interference 2 as an example of a particularly strong form of interference that will take quite a lot of effort to overcome.


The basic resolution of a situation is called a Task, and Star Trek Adventures breaks Tasks down into the following variants based on the resulting outcome of success or failure:

  • Tasks to succeed or achieve an objective, or one that could be used to generate an Advantage or Complication Trait for the situation.
  • Tasks to avoid hazards or danger. Success means avoiding harm, while failure means taking some form of damage.
  • Tasks to succeed but with something at stake. Instead of being a simple test of being able to just succeed or fail, failure here comes with a hazard.

Attributes, Disciplines and Focuses

Characters in Star Trek Adventures are described by their Attributes, Disciplines and Focuses.

Attributes in the game are: Control, Daring, Fitness, Insight, Presence and Reason. These range in values from 7 to 12.

Characters also have six Disciplines: Command, Conn, Engineering, Security, Science and Medicine. These range in values from 1 to 5.

Characters also have Focuses, which represent specialized training within a specific field. Focuses do not have a rating of their own.

Performing Tasks

Attempting a Task in Star Trek Adventures is a fairly straightforward affair:

  1. The GM determines the combination of Attribute and Discipline to add together. This forms the target number of the roll, as well as any applicable Focus.
  2. The GM also determines the difficulty of the roll. The difficulty is the number of successes that need to be made in order to succeed at the task.
  3. The Player then rolls 2d20, and tries to roll equal to or below the Target Number. Dice that do are considered to be successes.
    1. Players may also add more d20s to the dice roll by spending Momentum, adding to Threat or using Determination (More on those later)
    2. Rolling a 20 is causes a Complication. (we’ll tackle this one a little later on too)
    3. If a Focus is applicable, then any die that rolls a result equal to or less than the Discipline being rolled counts as 2 successes.
    4. If no Focus is applicable, then any die that rolls result of 1 counts as 2 successes.
  4. If the number of successes rolled match the difficulty of the roll, then the character is successful. Otherwise the character is considered to have failed the attempt.
  5. Any successes rolled that are over the Difficulty then become Momentum.

Traits and Task Difficulty

Standard Difficulty for most tests is 1. But Traits can come in to modify that difficulty, by either lowering it or raising it depending on the circumstances.

Improving the Odds

As you can tell, succeeding in a Task with a Difficulty of 2 or higher is going to be very difficult with just 2d20 as a basic roll. Because of this, characters have some means to add dice to their roll to a maximum of 5d20.

  • Spend Momentum – Momentum is a special resource generated by rolling successes over the difficulty of a roll. This is then banked in a special pool that can be used by all Player Characters in a group. The first die bought this way costs 1 Momentum, the second costs 2 Momentum and the third costs 3 Momentum.
  • Add to Threat – Threat is a GM resource that increases as players add to it at the same rate as Momentum.
  • Talents – Some talents bestow a bonus d20 to a roll where the Talent applies.
  • Determination – In certain situations, a character is allowed to spend Determination. Each point of Determination spent adds a d20 to a roll, except that this is assumed to have rolled a 1, therefore automatically adding 2 successes to the Task.


Rolling a 20 on a task generates a Complication. This is a Trait that is detrimental to the situation and can make success more difficult or certain actions impossible to do. If a player doesn’t want to take a Complication, this can be bought off at the cost of 2 Threat.

Success at Cost

Sometimes, a GM may allow for a roll to succeed at cost. In these cases, the player still rolls, but a failed roll can be turned into a success at cost of one automatic Complication. This is on top of any 20’s rolled in the attempt.


Momentum is one of the key mechanics that I enjoyed in Conan, so I’m happy to see it back here. As mentioned earlier, rolling more successes than the difficulty translates those successes to Momentum.

In addition to buying more dice to add to a roll, Momentum can also be spent to:

  • Create an Advantage – By spending 2 Momentum, a player can produce an advantageous circumstance relating to the action taken. This can also be used to remove a Complication in play, or generate a Complication for an opponent
  • Create a Problem – A player can declare that they are spending Momentum to make a task being performed by an adversary more difficult, at the cost of 2 Momentum per level of Difficulty increase.
  • Obtain Information – By spending 1 Momentum, a player performing an investigative or research task can ask the GM one question relating to the situation, or item, object or creature being studied.. The GM is compelled to answer truthfully, though not necessarily with complete information.


Threat is the GM counterpart to Momentum and is usually spent in a similar way to empower opponents. The difference is that Threat can also be spent to add reinforcements to the bad guys, or to trigger environmental effects that could create Complications for everyone in the scene.


Determination is a rare resource for characters of Star Trek Adventures. Each Player Character begins a game with 1 point in Determination with a maximum of only 3 points of Determination at any given time.

The use and gaining of Determination relies on a Player Character’s Values.


Values are short phrases or statements that describe the attitudes, beliefs and convictions of a character.

Should a character find themselves in a difficult situation where their Values can come into play, they may spend Determination to do any of the following:

  • Perfect opportunity – Grant a Task a bonus d20 that counts as having rolled a 1
  • Moment of inspiration – Reroll all the dice in a dice pool
  • Surge of activity – Perform a second Task immediately after the first
  • Make it so –  Automatically create an Advantage in the scene

Values are core components of a character however, and as such they can be tested as well. If a character is put in a situation where their values would make a situation more difficult, the GM may offer a point of Determination to compel the character to act in accordance to their Value, at the cost of a Complication. This is an optional offer, and it is up to the player to accept it.

Once per mission, if a character is put in a situation where their Value negatively impacts the situation, the character may choose to challenge it, striking it out of their character sheet and rendering it useless for the rest of the mission. In exchange they get a point of Determination. At the end of the mission, the player may then replace the challenged Value with something else that reflects their new worldview.

Advanced Training

The Advanced training section introduces Challenges and Extended Tasks, two optional subsystems for emulating long-term or multi-step tasks, such as “Reach main engineering and shut down the drive core.”

These are presented in terms of structures for tasks, including variants for timed, linear and gated challenges that I can see use for in Engineering sections of Starfleet just to keep a ship going.

Okay, that was a long read. Star Trek Adventures is clearly sitting on the Rules-Medium end of the spectrum, but the rules are clearly well thought out and have a place in the world. While I was worried about Momentum mechanics making them feel too pulpy, in the end the altered Momentum Costs, and the necessity for the Values to come into play before enabling spends of Determination help adjust that to a more human level of play.

I’m seeing a lot of influences from Fate’s Aspects and even a couple of ideas from Exalted Intimacies in play here and I really like what they’re doing. Star Trek isn’t about the phasers and neat space ships alone after all, but the struggle to do the right thing in difficult circumstances with little to no support.

Next up, we’ll finally start getting busy by building our first Starfleet character with our Let’s Study of the next chapter: Reporting for Duty.


Moving on from the discussions on the history of the Federation, we’re taking a look at the chapter that best displays the kind of thing that Starfleet actually does. Much like in the prior chapter, Your Continuing Mission is broken down into subsections.

Starfleet’s Purpose

For those unfamiliar with Starfleet’s role in the setting, this section breaks it down into what Starfleet is, as both a scientific and exploratory organization and one that is also saddled with the task of peacekeeping.

I like that the setting is well aware of the paradox of being a “neutral” force armed with enough weapons to scour a planet if need be, but for the sake of being ready for anything they might encounter in the frontier, Starfleet should be able to defend itself should the worst come to pass.

There’s also a short segment on Starfleet’s organizational structure. It’s handy to know and they’ve kept it short and to the point and more importantly playable without devolving into too much detail that won’t see play.

The Prime Directive

Allow me to take a moment to say that I LOVED this section. As a fan of moral / ethical dilemmas such as the classic Honor vs. Duty of Legend of the Five Rings, Star Trek Adventures tackles Starfleet General Order One, or the Prime Directive head on for what it is.

To those who don’t know of it, The Prime Directive is a guiding philosophy behind Starfleet that prevents their personnel from interfering with the natural development of other civilzations by abusing Starfleet’s technological superiority.

It was put in place to avoid contaminating the development of pre-warp civilizations and letting them grow on their own.

Naturally, this is one directive that is fraught with a tremendous number of ugly realities. Non-interference looks great on paper, but many Starfleet captains have erred on the side of getting involved for the sake of their crew, or their own morals.

In many ways, this is the soul of Star Trek, and one that I find to be a crucial part of the Star Trek Adventures RPG as it helps paint the conflicts that every Starfleet crew will encounter in their voyages.

Starfleet Academy

This section details the entire experience of going through Starfleet Academy. How they select students, what the time spent in the Academy is like, what bonds they foster among contacts and what values they foster in their students.

It’s a great look into the training that happens before the characters come into play, and I can totally see this working as source material if the group wanted to play a Starfleet Academy game where the players are all still students trying to make the grade.


The various departments of the members of Starfleet are described here. Depending on the training and course of study, graduates of Starfleet Academy are assigned to: Command (gold shirts), Sciences (blue shirts) and Operations (red shirts).

This section also discusses the way that Starfleet personnel are assigned to various ships and perhaps on a per mission basis.

Missions for the ships are also discussed here, from the original “five-year mission.” to longer, open-ended deep space missions made possible with new technologies. Some examples of missions and Directives are provided as examples, and these span from more broad statements like “Explore Strange New Worlds” to more specific ones like “Patrol along the Romulan Neutral Zone.”


This section gives a more detailed look at the various missions of Starfleet ships, and serves as a very fertile ground for GMs looking a what kind of adventures to throw at his intrepid crew of Player Characters.

These are broken down into Science, Diplomatic and Protection and Security missions, each of which has a thorough list of examples. Fans of the series will recognize many of these as near-tropes but they’re definitely endlessly repeatable.

Away Teams

As part of Starfleet operations, sometimes it’s important to put actual boots on the ground. As such the practice of putting together highly-skilled Away Teams that perform hands-on operations for the mission was established.

This is a high-risk assignment, and only the best of the crew are selected based on their capabilities and the nature of the mission. Given the broad range of various missions that the Away Teams can be sent on, I imagine that you’d be sending a different team on certain types of missions.

I might be pre-empting stuff that might be brought up later in the book, but I can certainly see a case being made for Troupe-Style play where players might have 2 or 3 different characters on the ship to make sure that no matter what kind of mission they’re on, they’ll have someone to participate in the action.

After my slight disappointment with the sections in the history chapter, this one blows me away. I’ve always been a fan of the sense of wonder and optimism of Star Trek, but as a much older geek, I also recognize that The Prime Directive can’t cover all situations.

There’s a lot of information in this chapter that answers the central question of RPGs, which is “Okay, but what do the player characters do?”

There’s clearly a lot of work done in Starfleet, and only the best are called to serve. This chapter has me stoked to run a game right now, and that can only be a good thing.

Next up, we’ll be taking a look at the mechanics behind the Star Trek Adventures RPG, and see how the 2d20 system was adapted to best emulate the Star Trek’s brand of action and adventure!

Today we start checking out the setting chapters of the new Star Trek Adventures RPG from Modiphius!

This chapter talks about The United Federation of Planets as well as the various other known factions in the Star Trek Universe. It’s divided into four subsections that we’ll tackle in order:


As a newbie to the Star Trek universe, the Overview served as a swift introduction to the Star Trek Galaxy, with small sections talking about the four Quadrants and the various factions and races that live there, along with what the current situation is with each of them.

While some familiarity with the setting helps here, as I’m unable to tell a Bajoran from a Cardassian at this point (though I suspect I’ll figure that out once we get to Character Creation) the way it was written was clear enough to at least follow along and get the broad strokes as to the conflicts and issues plaguing each of these groups.

There’s also mention here of some of the other truly alien threats like the Borg and the Q, which I’m sure will be a cause of no end of misery (or amusement) to the players when confronted by these threats in the game.

Early History

In a surprising shift, the Early History section switches to a “show, don’t tell” approach by presenting this entire section in the form of several missives taken from various personalities from different factions.

These range from diary entries to excerpts of a lecture talking about the origins of the infamous Khan Noonien Singh, to entries from the personal log of Captain James T. Kirk. While each of these offers insight to a slice of time, and the mindset of their respective authors, the overall effect was a bit confusing.

I came out of this section feeling a little more lost than enlightened, and I wasn’t certain how to parse the information in the letters in a way that would help me run the game.

The Twenty Third Century

This segment deals with the role of Starfleet in the greater scheme of things, and the expectations of the people that serve in it. Rather than delve into the history of things, the section talks about the nature of those that serve Starfleet as explorers as a primary function.

There’s some fine talk here about the virtues of improvisation in the face of the uncertain, the importance of their jobs as Diplomats, Explorers and Peacekeepers. It’s a great read honestly, and one that helps pin down just what makes members of Starfleet so heroic in the way they uphold these virtues.

Recent Federation History

Here we go back to the letters and missives. Again while I do appreciate the insight, I wish that there was some more structure provided to give someone like myself who doesn’t have an extensive familiarity with the setting something to hold on to in terms of context for each of these entries.

Again, I suspect that these letters are great if you’re familiar with the setting, but for someone like myself, I found them to be something that I would skip over at least on my first read-through.

Next up we’ll be taking a look at the next chapter: Your Continuing Mission. This section details the more relatable details of being a member of Starfleet, and it’s a chapter that I’m really looking forward to sinking my teeth into given the fact that I’ve always admired Star Trek’s focus on stories that revolve around the missions that don’t involve eradicating an alien species, but rather tackling the issues surrounding the nature of contact while working under The Prime Directive.

After an overwhelming victory on votes against Shadowrun 5th Edition in a Twitter poll, we’ll be doing a Let’s Study on the freshly minted Star Trek Adventures RPG from Modiphius!

Disclaimers and Background

I was lucky enough to receive this electronic review copy from Modiphius. Also, I’m not all that familiar with the world of Star Trek, having only watched a few of the movies and some episodes of the original Star Trek, and Star Trek: TNG on local TV.


“Space. The final frontier. These are the voyages of the starship Enterprise. Its continuing mission: To explore strange new worlds, to seek out new life and new civilizations, ,to boldly go where no one has gone before.” – Captain Jean-Luc Picard.

As a geek of any stripe it’s not difficult to get goosebumps at this opening line, and in my head it rings with the same weight as Conan’s “Know, oh, prince, that between the years when the oceans drank Atlantis…”

It’s a daunting thing to tackle Star Trek, with such a heavy legacy from so many sources, but the book jumps right into it.  What I really appreciated is how easily they broke down the kinds of adventures you can expect. For those used to the lore of the setting, you can participate in any of the various hotspots of the Federation against its neighbors.

There’s mention of the U.S.S. Enterprise 1701-D, the U.S.S. Voyager and the U.S.S. Defiant, as well as the conflicts and missions they were to encounter. These would be the template of the kinds of adventures that the player characters, as members of Starfleet can expect to participate in: from high-stakes politics, to first contact with strange and alien species and participating in exploratory and scientific missions.

The Basic Mechanics

Star Trek Adventures uses the 2d20 system that Modiphius has used in several other games, such as Conan, Mutant Chronicles and the upcoming Infinity RPG.

Whenever an action is taken with a risk of failure the character rolls a pool of 20-sided dice (usually 2, but that can be increased with other factors) and tries to roll below a value determined by their Attribute and Discipline.

Of course, there’s more to it than just rolling 2d20 under a target number, but we’ll talk about those as we run into them on the rules.

In our next installment, we’ll be taking a look at the setting and history of the Start Trek Adventures RPG. It’s a hefty chunk of the book but I’m looking forward to checking it out as I want to better appreciate the next bit after that Starfleet and Character Creation!

EDIT: Seeing as a lot of you are finding the first article linked in various sites, I figure I might as well link to the rest of the entries as I write them: Part 2, Part 3, Part 4 (Mechanics), Part 5 (Character Creation)
