What class felony is conspiracy to common law robbery?

North Carolina has a structured sentencing scheme.  Conspiracy to commit a felony is one class below whatever the felony is.  So Common Law Robbery is a G felony, which means it is "non-violent" but "serious". 

Conspiracy to Commit Common Law Robbery is a Class H felony, which means it is a "non-violent" but "serious" crime.

For someone with no convictions, a Class H felony Level 1 offender is in a C/I/A block which means anything from probation, to community service, to an active sentence could be imposed.  At the low end, you're talking about approximately 6 months in jail if sentenced to an active sentence, which would be unlikely for a Level 1 offender.
