Editing GURPS (section)

===Skills===
Complementing the stats are numerous skills. A player buys skills with character points. Skills represent physical and mental areas of specialty which can prove useful in the game. Skills vary widely, from Acrobatics to Vehicle Piloting. The availability of skills depends on the particular genre the GURPS game is played. For instance, in a Medieval Fantasy world, skills for operating a computer, or flying a fighter jet would not normally be available for the player to choose unless they time traveled. Skills are rated by level, and the more levels purchased with character points, the better the character is at that particular skill. 

Skills are categorized by difficulty: Easy, Average, and Hard. They are also categorized as Physical or Mental skills, with Very Hard as an option for some Mental skills. Easy skills cost fewer points to purchase levels in, while Hard skills cost more. A player can purchase a skill for his character at any level he or she can afford. The lower you choose the fewer points it costs to buy the skill, and the higher you go, the more points it costs. Some skills have default levels, which indicate the level rating a character has when using that skill untrained (i.e. not purchased). For example, a character with a Dexterity of 12, uses the Climbing skill untrained. Climbing has a default of DX-5 or ST-5, which means that using the skill untrained gives him a Climbing skill level of 7 (12-5) if he tied it to the Dexterity stat. If the character had a higher Strength stat, he could have a better chance of success if they tied the Climbing skill there instead.

Many Skills also have a Tech Level (TL) rating attached to them, to differentiate between Skills that concern similar concepts, but whose tasks are accomplished in different ways when used with differing levels of technology. This helps during time traveling scenarios, or when characters are forced to deal with particularly outdated or advanced equipment. For instance, a modern boat builder's skills will be of less use if he is stuck on a desert island and forced to work with primitive tools and techniques. Thus, the skills he uses are different when in his shop (Shipbuilding/TL 8) and when he is on the island (Shipbuilding/TL 1).
