How Skills work in Star Trek RPG
Skills in Star Trek RPG are grouped into Skill Sets. Characters get their skill proficiencies based
upon Class and Advanced Training. Characters can use skills that they are not proficient in but
they will receive a –5 modifier to all rolls in reference to Skill Checks they are not Class
proficient in. Skill Points may be allocated into any Skill regardless of whether the character has
a Class proficiency with that Skill Set or not unless specifically noted.
The maximum number of ranks a character may have in a given skill is 4 + 1 per level, maximum
16 ranks.
Skill Points are also gained dependant upon class and level. See the particular Class or Advanced
Training description to see how many Skill Points a character gets per level.
For critical success and failure, please consult the following chart.
Skill Check Success/Failure Table
Results Failure by 16 or more
Absolute failure. No further attempts allowed for 24 hours. If possible, your attempt has the opposite
effect from what you intended.
Failure by 9 - 16
You zone-out while attempting your action and fail miserably. No further attempts allowed for one
hour.
Failure by 1 - 8
You almost got it. You can try again immediately with a +2 bonus to your roll.
0
Congratulations, you made it!
Success by 10 or more
You’re good. You’re so good you can take +5 to all other Skill Checks in the next 15 minutes.
[GM – not sure about that!]
How to make a Skill Check
In order to attempt a Skill Check a player must roll a d20, add the number of ranks their character
has in the skill, add the respective ability modifier and then add any other miscellaneous bonus.
If the resulting number is equivalent or higher than the Skill Check’s Target Number, then you’ve
succeeded. If the result is lower, the attempt fails.
A simple task (using a Tricorder to analyze the structural integrity of a building) would have a Target
Number of 14, whereas attempting to isolate the bio-sign of a specific individual on a Space Station
would be more difficult with a prospective Target Number of 28.
The Game Master should determine target Numbers for Skill Checks. Below is a description of all the
skills in the Star Trek Role Playing Game. Within each description you will find recommended uses
and which ability modifier to add to your Skill Check rolls.
