Biotic Power Usage
Unlike other Skills, Biotic Power Usage only offers a bonus to any check for the use of one specific Biotic Power. To receive a bonus on multiple Powers, this Skill must be assigned multiple times, once for each Biotic Power. The Skill is useful to a character who may not have a high ability (such as Intelligence) that is associated with one of his or her Powers (such as Telepathy).
Check: When the character must make a check for the specific Biotic Power, the Biotic Power Use Skill adds a bonus as though the check is actually a Skill check.
