Inspire Competence

A bard of 3rd level or higher can use his performance to help allies succeed at a task. They must be within 30 feet and able to see and hear the bard. They get a +2 competence bonus on all skill checks as long as they continue to hear the bard's performance. This bonus increases by +1 for every four levels the bard has attained beyond 3rd (+3 at 7th, +4 at 11th, +5 at 15th, and +6 at 19th).
