Deduction

From Viridian TTRPG Wiki
Jump to navigation Jump to search

The Deduction skill is focused on identifying the features and properties of the world around them. Whereas a skill like Tactics requires you to memorize specific creatures or environment types, Deduction is simply separated by three major subjects Animate Beings, Environments and Objects, all viewed through the lens of logic and intuition. An Adventurer can call upon their Deduction skill in order to try and find hidden and secret aspects of a particular individual, environment or item; or to simply understand what it is in the first place.

If a check is time-sensitive, the Adventurer may only get one chance to use Deduction successfully. For more lengthy investigations without interruptions or agency, the Adventurer may see the maximum possible result based on their Deduction skill so long as the check does not exceed 50 + their Deduction Skill-Rating.

An Adventurer can make Deduction checks without any skill-rating as they add 10 * their Perception attribute score to their roll.
