Here a feat I made, that I hope brings a little of the 3.x D&D feel to the 4Etable D&D.
Prerequisite: Training in chosen skill
Benefit: Choose a sub use of a skill in which you have training. You have a +3 feat bonus to checks with that sup use of the skill.
Special: You can take this feat more than once. Each time you select this feat, choose a different sub skill. Will stack with Skill Focus.
In example, with the skill Thievery a Player can specialize in Disable Traps, Opening Locks, Picking Pockets, or doing Slight of Hand.
Because this feat was designed with 4E in mind, it should work with Star Wars:Saga Edition with little or no changes.
