Sometimes, tests are not initiated by the player characters’ actions, but are reactive saves, aimed at avoiding or mitigating an external danger threatening them. A character instinctively throws themselves on the side to avoid a falling stone. A character is confronted with a trauma from their past and must brace themselves to be able to act. Etc.
The mechanics are the same as a standard test, but only one success is needed for the save to be successful.
- Physical: everything related to the body, vigor, and material survival.
- Mental: everything related to the mind, concentration, psychic or magical resistance.
- Social: everything related to charisma, willpower in the face of others, resistance to social or supernatural pressures linked to interaction.
