Prerequisite: Advanced talents

Benefit: The rogue becomes so confident in the use of certain skills that she can use them reliably even under adverse conditions. Upon gaining this ability, she selects a number of skills equal to 3 + her Intelligence modifier. When making a skill check with one of these skills, she may take 10 even if stress and distractions would normally prevent her from doing so.

Special: A rogue may gain this special ability multiple times, selecting additional skills for skill mastery to apply to each time.
