He can then cast that ritual with only a -3 modifier instead of say -10. And that looks like a bug.

Was it intended that way, and if not, how can it be fixed?

Yes, it attaches, then you roll at your skill at -3. If your skill is a 6 and you have to roll for the spell it's a 3 or less meaning your critically fail on 13 or more. That's...not great.

You can absolutely raise the penalty higher, I originally used -5 but the playtesters thought that was too harsh.
