SN 2023dbc is a moderately energetic, highly obscured Type Ib supernova with estimated kinetic energy 4.1e51 erg, ejecta mass 2.3 solar masses, and nickel mass 0.038 solar masses, consistent with an aspherical explosion and partial fallback from a 15 solar mass binary progenitor that retained helium
