So in the core book each skill has a number of applications listed. Furthermore the Applications paragraph states:
Every skill has applications, which are sub-areas of the skill.
If a skill check involves a certain application, it appears
in parentheses, as in Perception (Spot). This is important
when determining whether a hero can use a certain
advantage or special ability. A check for Perception (Spot)
means that the skill involves the specific application Spot
Does this mean anyone who has a Skill, like say Religions, will automatically be able to make a roll for any of its applications without incurring a -3 penalty aside from those that require a certain advantage, special ability or trade secret?
Example 1: Born has a SR of 5 in Religions. He finds a small idol in a temple of praios. To know more about it he makes a skill roll Religions (praios). He will NOT take a -3 penalty to his roll because he has points in the skill and so automatically knows the applications.
Example 2: What about untrained use of skills? Say Born doesn't know the Religions skill. Would he still make the Religions(priaos) roll using only his attributes but without any penalty, or would he take the -3 penalty for not having even a single SR in the skill?
