The Nexus Framework uses a light and flexible skill structure. There are only twelve broad skills, each tied to a single attribute. A character’s focus within a skill can be refined through Skill Traits, which represent specialization or expertise.

Each skill in the game has an associated training value, which represents a character’s competence with that skill. Skills can be either trained or untrained:

If a skill is untrained, the character has no formal ability in it, and its value is +0. The character can still attempt the skill, but they rely entirely on the governing attribute and any situational modifiers.

When a character first becomes trained in a skill, that skill receives a value of +2, reflecting basic proficiency.

Trained skills improve over time. Upon reaching levels 2, 8, and 13, any skill a character has trained will gain an additional +1 bonus to its value. Further specialization is possible: certain traits allow characters to gain bonuses to skills within specific fields, representing focused study, practice, or innate talent.

Whenever a character is directed to make a skill check, they must do the following:

• Roll 2d10.
• Add their skill's training value, plus the controlling attribute's modifier.
• Consult the Success Table to determine how well they did.
