Leveling Guide: Fast XP & Attribute Training

Leveling covers how Duplicants gain experience, earn Skill Points, and raise attributes and skills — the mechanics that make Duplicants more effective at tasks and unlock abilities. Properly managing leveling determines research speed, construction/mining throughput, running speed, and many other colony efficiencies.

What levels and attributes exist

• Duplicants earn two distinct progression types:
  • Skill Points (used to learn skills in the Skills menu).
  • Attribute levels (the 11 numeric attributes like Construction, Excavation, Science, Athletics, Cuisine, Creativity, Machinery, Strength, Learning/Research-related; each attribute grants specific bonuses per level).
• Every attribute can be trained up to a maximum increase of +20 from training (this stacks with starting bonuses and trait modifiers).
• Skills are purchased with Skill Points at the Printing Pod and are semi-permanent; they may add abilities or increase attributes further and incur morale expectations.

Starting bonuses and Interests

• When a Duplicant is created they receive between 1 and 3 random Interests.
• Each Interest grants a starting attribute bonus to the related attribute(s):
  • 1 interest: +7 to that attribute
  • 2 interests: +3 to each related attribute
  • 3 interests: +1 to each related attribute
• Trait-provided Interest Attribute Modifiers are applied after these base values and are split across multiple interests if necessary.
• The starting bonuses are a hard floor: an interest will always provide at least the listed bonus regardless of negative trait modifiers.
• Interests also:
  • Provide a +1 Morale bonus when the related Skill is mastered.
  • Increase experience gain from tasks associated with that Interest (so Skill Points from those tasks are earned faster).

Experience sources and rates

• Passive experience: Duplicants passively earn experience at a base rate of 0.5 XP per second.
• Active-task experience: while actively performing a task, a duplicant gains 0.6 XP per second by default (this is the starting point used in further formulas).
• If the duplicant has an Interest matching the errand, the experience rate increases according to the errand’s assigned frequency:
  • The formula used internally is: XP_gain = 0.6 × (1 + 0.5 / f_frequency).
  • Frequency categories (examples of errands):
    • All day (f_frequency = 0.9): highest baseline frequency (e.g., researching, telescopes).
    • Most of the day (f_frequency = 0.75): common tasks (e.g., ranching, constructing, digging, cooking).
    • Part of the day (f_frequency = 0.5): less common tasks (e.g., cleaning, harvesting).
    • Barely ever (f_frequency = 0.25): rare tasks (e.g., medical stations, attacking).
  • Rarer-frequency errands yield proportionally more XP for interested duplicants.

Skill Points: how they are gained and spent

• A Duplicant gains Skill Points after accumulating enough total experience; the total XP required for N Skill Points follows a scaling formula:
  • TotalExperience = 150000 × (SkillPoints / 15) ^ 1.44
• The Skills menu shows progress toward the next Skill Point as XP earned since the last point; the displayed current and max correspond to the difference between consecutive total-experience thresholds.
• Spending a Skill Point:
  • Is instant and the Duplicant visits the Printing Pod to master the skill.
  • Applies the skill’s effects immediately (attribute increases or new abilities).
  • Adds to the duplicant’s morale expectations: the sum of all skill morale costs becomes part of their morale baseline. Interests reduce the morale cost of the matching tier-1 skill by effectively making it free (they grant +1 morale when mastered).
• Skills can be reset with the Skill Scrubber if you want to change a duplicant’s loadout.

Attribute leveling and Science interaction

• Attribute gains (the numeric attributes like Construction, Excavation, Athletics, Science, etc.) are earned by performing the errand type tied to that attribute.
• The Science attribute is special:
  • It increases how quickly all other attributes level: a higher Science level multiplies attribute leveling speed.
  • Science also increases Research speed and speeds up attribute leveling (tooltips and some historic descriptions may have been misleading; Skill Point gain is identical for all duplicants — Interests affect XP gain for particular activities).
• Because Science multiplies attribute gains, it is efficient to train Science early if you plan to raise many attributes.
  • Recommended strategies: dedicate a single duplicant with a Research interest to cap Science, or use a small number of dedicated researchers if Morale is a constraint.
  • Renewable sources of Science XP include Research Stations, Geyser analysis, Botanical Analyzer (Spaced Out! DLC), and repeated geotuning/analysis tasks.

Practical training tips

• Use Interests to your advantage: assign duplicants to tasks matching their Interests to accelerate their Skill Point gain and starting attribute bonuses.
• For single-attribute specialists (e.g., builders or miners), selecting duplicants with matching Interests gives a strong starting boost and faster training.
• To train Science for a long-term benefit to all attributes, focus a dedicated duplicant on research errands early; once Science reaches its cap you can switch to training other duplicants or let them cross-train.
• Some errand types are limited in total raw experience (base-game research has finite tasks); plan for alternate/renewable XP sources (automation that repeats relevant tasks, Botanical Analyzer in DLC, or repeating analysis tasks).
• Remember Morale: each skill learned adds to a duplicant’s morale expectations. Master interests and low-tier skills first (they effectively cost no morale when they match an Interest), and use the Skill Scrubber to reconfigure skills if morale problems arise.

Mechanics summary

• XP sources: passive (0.5 XP/s), active task (base 0.6 XP/s), increased by Interest + frequency modifier.
• Starting bonuses from Interests: +7 / +3 / +1 depending on whether duplicant has 1/2/3 interests.
• Attributes cap from training: +20 from training (on top of starting and trait modifiers).
• TotalExperience scaling for Skill Points: 150000 × (SkillPoints / 15) ^ 1.44.
• Science speeds up attribute gains and research; train it early for long-term benefit.

Use these rules to plan which duplicants you recruit, which jobs you assign, and whether to dedicate specialists for early speed or cross-train the workforce for flexibility.
