A skill-level of 4 can only be gained with Class-Skills, which have to be taken (s.u.).
Beginning Skillpoints are (2+int)*4.
The 20 Skill-points on 0.1st level are virtual, because 14 points are automatically spent for the Commoner-package: Mage Attack-Base (4 CP), 2 Skill-Points (5 CP), 10 Class-Skills (5 CP).
In the Orfinlir-Setting a character receives a bonus skill on level 0.1. This feat must be a background-feat specified by the region the character comes from.
Weapons as Peasant. By spending 5 CP on a specific Skill, the Charakter is allowed to increase this Skill above his normal Limit, up to a rank equalling the corresponding attribute. These 5 points are spend for the allowance, not for raising the skill.
Skill Points to spend on skills can be taken from the initial, from charakter points, from bonuses through raised attributes or from increased Skill-Point allowance.
Disadvantage: more XP then change from Commoner Class.
Advantages: more Charakter-points to build the charakter more HP (with the possible exception of Barbarian and very seldom Fighter, Ranger and Paladin) not restricted in multiclassing through Commoner Class to get the one charakter, you imaged.
