Military skills deal with combat. There are seven different Military skills: Beam Weapons, Demolitions, Gyrojet Weapons, Martial Arts, Melee Weapons, Projectile Weapons and Thrown Weapons.
Technological skills deal with various types of machines. There are three different Technological skills: Computer skill, Robotics and Technician.
Biosocial skills deal with the intelligent races and their surroundings. There are three different Biosocial skills: Environmental, Medical and Psycho-Social.
At the start of the game, each character must choose one Primary Skill Area as his career. The player then chooses two skills for his character. One skill must be from the character's PSA, but the other can be from any PSA. The character starts with Level 1 experience in both skills.
| Military PSA | Technological PSA | Biosocial PSA | |
| Level 1 | 3 (6) | 4 (8) | 5 (10) |
| Level 2 | 6 (12) | 8 (16) | 10 (20) |
| Level 3 | 9 (18) | 12(24) | 15(30) |
| Level 4 | 12 (24) | 16 (32) | 20 (40) |
| Level 5 | 15 (30) | 20 (40) | 25 (50) |
| Level 6 | 18 (36) | 24 (48) | 30 (60) |
A character can learn only one skill level at a time. Skipping levels is not allowed, even if the character has enough experience points to do so.
EXAMPLE: Brango O'Bourke, a Human, has accumulated 10 experience points on adventures. The player decides to spend these experience points to increase Brango's Gyrojet Weapons skill from level 2 to level 3. Brango's Primary Skill Area is Military, so the new level costs him 9 experience points. The player increases Brango's Gyrojet Weapons skill level from 2 to 3 on the character sheet, and subtracts 9 from his experience point total. Brango has 1 experience point left.
Training. When characters learn new skills or increase a skill level, they must be trained somehow. Three methods are described below.
HYPNO-TRAINING. Hypno-training is a teaching system that involves hypnotism, memorization and the use of drugs that improve the mind's ability to learn. A character with enough experience points can learn a new skill or skill level at a hypno-training center in five days (100 hours) for 100 Cr.
TEACHERS. A character with enough experience points can learn a new skill or skill level from another character. The teacher's skill level must be at least two levels higher than the pupil's. A character can learn a new skill or skill level from a teacher in one month.
PRACTICE. Characters with enough experience points can learn new skills or skill levels simply by practicing. This is not always possible, however, especially with skills that require special equipment.
All three of these methods are optional. Some referees may want to ignore this rule, and simply allow players to pick new skills when their characters have earned enough experience points. Training is more realistic, but also more complicated.
