Tutor
You share your skills with an ally.
Activity
Choose a skill in which you have at least 3 ranks. You spend the day teaching a willing ally whose number of ranks in that skill is at least 3 lower than yours; the ally must use their downtime studying with you. At the end of the day, your ally attempts a DC 10 ability check, using the ability associated with the chosen skill.
Results
If your ally succeeds at the check, they count as being trained in that skill until the end of the following day. In addition, before attempting a check with that skill, the ally can add a +3 insight bonus to their check; they can apply this bonus three times during that day.
