Upon completing a character's Loyalty Mission, that character will gain their loyalty power for use. In addition, if Shepard researches Advanced Training at the research terminal in Mordin's lab, he or she can learn a single loyalty power as their "bonus power"; any subsequent times Shepard undergoes Advanced Training the new power selected will replace the old one and the skill points allotted to the old power will transfer to the new bonus power. Any bonus powers earned in previous playthroughs will be available at the start of any new game at character creation and at a research terminal.
