Content: A roster of sacred artifacts and relics
Writing: Clear descriptions of item’s functions in a grimly spiritual tone

“Slasher Jam was a jam I ran over the course of October 2021 that got 20 entries. I have compiled those entries into 2 volumes. Volume 1 contains classes, items, and monsters. Volume 2 contains the adventures of Slasher Jam.” – Michael Mars, ed.
