Good finds, thanks! I’ve just uploaded a new version with those things fixed, plus a couple of others :)
To answer here too:
Section 2: Yes, it should be Restore. I would stat the Beetle/Pack rat as a hireling, maybe with slightly adjusted stats.
Section 7.2: 4-6 is correct.
Section 11.2: Intentional, but confusing. I’ve just made it d4-d20.
Thanks, I appreciate the nit-picks!
