Research Mastery is a Mostly Harmless Forbidden research option under the Basic Information tab that becomes available for research after researching Research Expertise. It adds onto the benefits of Research Expertise, now giving a 50% chance to reclaim any aspects placed into the research grid. In addition to this, there is a 10% chance that an aspect will not be used when placing it onto the grid, allowing for aspects to last longer. Finally, one can shift click on any aspect to, if the needed aspects are present, create said aspect. All the prior benefits of Research Expertise that are not listed as being changed are still present.
