You don't have SRs, you have a small cult of worshippers that are part of the carnival. You can tap them for up to 15GP per Chapter and die once per Chapter for free. Further deaths per Chapter must be paid in GP or by lowering a stat.
Cult is a perk. It can be purchased for 40 points in character creation, or may be available free with faction membership in some stories.
This perk is or has been available in the following stories • Carnival of Wonders •
