Ridley's Cohort said:The missing '+' is probably just a typo.
If you compare it level by level with the familiar bonus, it would be almost identical. That is pretty compelling circumstantial evidence there should be a '+'.
But this particular typo has survived all the errata and it is also missing in the SRD though that has been reworked a number of times, I and several others did comment on the 'missing' '+' as earlier a few days after the PHB was published. It is my firm belief that it is not a typo.
