The Deity Disapproval table on page 122 lists the penalties for a Disapproval roll of 1 through 20+.
However, it appears to me that a roll of 0 or less is not only possible, but highly likely. The roll is
- Nd4 where N is the number on the failed spell check
- Less the cleric's Luck modifier
Since Luck is a basic stat (within 3-18) it seems like Disapproval rolls will be 0 or less until the cleric suffers several failures in a day (hence increasing N).
Does that mean there is no actual Disapproval?
