The original version of this rule booklet was sold by Bandit Camp briefly, before they withdrew it from sale.
This version is updated and has 5 additional pages.
The current Wicked Ones rules have a chapter on solo rules, but I found them to be excessively table-heavy, and kept me tied to the rulebook. My approach is more rules-light, and only use a pair of tables that can be easily printed off from the PDF.
This booklet can be used as a replacement for the corer rules solo chapter, or to augment it.
