Skill-System

Basics
There is one list of skills and every Class has a number of skills listed as Favored Skills and thereby any skill listed in one of your classes is a favored skill of your character. In addition you can train Favored Skills by various means and you can turn Skills into Favored Skills by multi-classing or by taking Feats. Also every class has one or two skills that you automatically train if you take a level in a class, so a wizard for example is always trained in Knowledge(arcana) and Spellcraft and a cleric is always trained in Knowledge(religion) and Spellcraft. Therefor a Cleric/Wizard would be trained in Knowledge(arcana,religion) and Spellcraft. Some automatically trained skills will be automatically focussed on advancing in your class.

This system is pretty narrow in terms of degrees of training. Without feats there are 3 levels: untrained, favored and trained. Through feats you may also have a skill rated as focussed or get an additional bonus to skills.

Skills by Class
As you can see under Conversion of Skillpoints there are a few special things to note. Classes with 2+INT see a split between primary casters and primary fighters between free and automatic choices. 4+INT characters get always two automatic skills and two to train. 6+INT or more gets something called a named set Every set consists of 3 skills and refers to an archetype: a rouge might take Spy or a Thief as skill Set. A bard may take for example Sage or Con Artist. GMs are encouraged to provide sets for their own campaign if appropriate.

Skills and Intelligence
You also get bonus Skills for having a high intelligence score. A character has his total of free choices (from all classes) adjusted by his Intelligence Modifier. So a Fighter with an Intelligence of 8 would get 1 automatic skill and one free choice if that Fighter would have an INT of 12 he'd have 1 automatically trained skill and 3 free choices. A Bard/Rogue with an INT of 8 has Disable Device and Performance, 2 named sets and 2 free choices, if he had an INT of 12 he would get 4 free choices. Therefor a wizard still gets a lot of free choices but these are most likely knowledge spells unless multi-classed.

List of Skills
The this comes along with a compressed list of skills. What happens to what skill can be seen in the table below. A row spanning over both columns means that all uses are preserved. Some Skills have been merged and some skills become Saving Throws others become feats and some may be split. There is a simple concept behind this: If it is defensive, it becomes a safe (Concentration, Tumble). It it is productive, it becomes a feat (Craft, Forgery and Profession). for everything else common sense applies.
