Resources. Typically, a character needs access to a library or a sage to conduct research. Assuming such access is available, conducting research requires one workweek of effort and at least 50 gp spent on materials, bribes, gifts, and other expenses.
Resolution. The character declares the focus of the research — a specific person, place, or thing. After one workweek, the character makes an Intelligence check with a +1 bonus per 50 gp spent beyond the initial 50 gp, to a maximum of +6. In addition, a character who has access to a particularly well-stocked library or knowledgeable sages gains advantage on this check. Determine how much lore a character learns using the Research Outcomes table.
Complications. The greatest risk in research is uncovering false information. Not all lore is accurate or truthful, and a rival with a scholarly bent might try to lead the character astray, especially if the object of the research is known to the rival. The rival might plant false information, bribe sages to give bad advice, or steal key tomes needed to find the truth.
