Skills

Instead of skills and weapon proficiencies being handled as separate systems, both are encompassed under the same system. Training in a skill now confers a +3 bonus instead of a +5 bonus, with the exception of weapons. The bonus conferred is the weapon’s training bonus (analogous to the proficiency bonus from standard 4E and listed in the weapon’s statistics for all weapons unique to Star Wars).

Skills and Defenses
Skills are an integral part of a PC’s defense rolls. A Defense action will typically list one or more skills or weapons. The PC adds the highest applicable training bonus to the Defense roll.

Changes to skill related feats:
Skill Focus: The +3 is distributed over the 3 tiers ( +1 immediately, +2 at 11th level and +3 at 21st level), just like the Weapon Expertise feats. This bonus is only added to skill checks not Defense rolls.
