Any Ritual maintained by a Character can be converted into a Project as a Free Action. An Entity can only turn a Ritual into a Project during their Turn. Once a Ritual has been converted into a Project, the Entity is free to move and otherwise act as normal without risking any progress on the Ritual. To resume the Ritual, however, the Entity must perform a Multitasking Save with an Appropriate Difficulty based on the Situation.
If the Situation is calm, such as during a rest period or at a work station, the Difficulty should be around 10 to 15. If the Situation is stressful or dangerous, such as at a loud concert, during a riot, or in a fight, the Difficulty should be around 15 to 25. If the Situation is disastrous or extremely stressful, such as during all-out warfare, life-or-death surgery, or while diffusing a bomb, the Difficulty can be 25 or higher, such as 30, 40, or even 50. Have a discussion to determine what feels Appropriate for the Situation.
If this Multitasking Save is performed Successfully, the Entity resumes the Ritual with the same Total it had when the Ritual was paused and converted into a Project. If they Fail the Save, the Ritual Fails instead. An Entity can only maintain a limited number of Projects.
