Character Advancement

Your character grows through experience, reflection, and the consequences of their choices. Advancement in Star Trek Adventures is driven by milestones — meaningful events where your character re-examines themselves and changes in response.

Personal Log

To track your character's growth, maintain a personal log. At the end of each adventure, write a brief entry:

  1. What happened — one or two sentences about the mission.
  2. Which Values you used — note V1, V2, etc., with + (used positively), – (used negatively), or ! (challenged).
  3. Whether you received a milestone — mark it in the log entry.

If you challenged a Value, rewrite it at the end of the mission to reflect how your character has changed.

Milestones

A milestone is a meaningful event in your character's life — a point where they re-examine themselves and change. You earn milestones by calling back to previous experiences.

Earning a Milestone

  1. During a mission, use one of your Values.
  2. Call back to a previous adventure in your log where you used the same Value.
  3. Describe how that previous experience influences what's happening now.
  4. Gain 1 Determination (still limited to the normal maximum of 3).
  5. Mark that log entry as used — each entry can only be used once.
  6. At the end of the adventure, you receive a milestone.

What You Can Change

After earning a milestone, choose one of the following:

ChangeLimits
Increase an Attribute by 1Max 11; each attribute only once per milestone
Increase a Department by 1Max 4; each department only once per milestone
Gain a FocusOne additional focus
Gain a TalentOne additional talent
Help a Supporting CharacterIncrease one of their attributes, departments, focuses, or talents
Adjust Ship SystemsReduce one system by 1, increase another by 1 (max 11, min 6)
Adjust Ship DepartmentsReduce one department by 1, increase another by 1 (max 4, min 1)
Swap a Ship TalentReplace one ship talent with another

Minor Adjustments

When you use a Value during an adventure (positively, negatively, or challenged), you may also make one minor adjustment:

  • Reduce one Attribute by 1, increase another by 1 (max 11, min 7)
  • Reduce one Department by 1, increase another by 1 (max 4, min 1)
  • Replace one Focus with a different Focus
  • Replace one Talent with a different Talent (you must meet prerequisites)

Character Arcs

Character arcs represent longer-term growth across multiple adventures. When you call back to a previous adventure that was itself a milestone, you create a character arc.

Completing a Character Arc

A character arc spans at least 3 adventures (initial adventure → milestone → arc completion). Each subsequent arc requires one additional adventure.

When you complete a character arc, you may choose one of these enhanced rewards instead of a normal milestone:

ChangeLimits
Increase an Attribute by 1Max 12 (higher than normal milestone)
Increase a Department by 1Max 5 (higher than normal milestone)
Gain an additional ValueA third Value for your character
Increase a Ship System by 1Each system may only be increased once per character
Increase a Ship Department by 1Max 5
Gain a Ship TalentMay ignore normal maximum

Reputation

Your reputation reflects how your peers and superiors regard you. It begins at 3 and ranges from 0 to 5.

Reputation Ratings

RatingStarfleet Standing
0Barely fit for service
1Poor record, future in question
2Uncertain, questionable performance
3Solid, satisfactory (default)
4Fine record, commendations for exceptional work
5Exemplary, the finest Starfleet has to offer

Using Reputation

When interacting with someone who knows you by reputation alone, you may use your Reputation rating instead of a department rating to create your target number. This represents your deeds and renown speaking for you.

The Reputation Roll

At the end of each mission, the GM asks a series of questions to determine positive and negative influences on your Reputation.

Positive influences include:

  • Mission was successful
  • Prevented or de-escalated combat
  • Established peaceful cooperation with others
  • Saved lives of innocents or crew
  • Rendered aid to those in distress

Negative influences include:

  • Mission failed
  • Disobeyed orders
  • Employed lethal force
  • Took unnecessary risks
  • Caused or allowed innocent lives to be lost

Making the roll:

  1. Target number = 7 + your Reputation
  2. Difficulty = number of negative influences
  3. Roll d20s equal to positive influences (no maximum)
  4. Each d20 ≤ target number = 1 success. Each d20 ≤ Reputation = 2 successes
  5. If successes ≥ Difficulty, you've acted properly. Each extra success becomes Acclaim.
  6. If successes < Difficulty, you suffer Reprimands equal to the shortfall.

Acclaim

Acclaim is spent immediately (not saved) on benefits:

Tips for Players

  • Keep your log updated. It's your roadmap to advancement — without it, you can't call back to previous adventures.
  • Use your Values. Advancement is driven by Values. If you're not using them, you're not growing.
  • Think long-term. Character arcs span multiple missions. Plan which Values you want to develop.
  • Spend Acclaim immediately. It doesn't carry over — use it or lose it.
  • Reputation matters. A high Reputation gives you social leverage. A low one creates obstacles.
