ASASSN-16fp), spanning the $\\gamma$-ray through optical and radio wavelengths, acquired within the first hours to $\\sim$420 days post explosion. Our campaign confirms the identification of He in the SN ejecta, which we interpret to be caused by a larger mixing of Ni into the outer ejecta layers. From the modeling of the broad bolometric light curve we derive a large ejecta mass to kinetic energy ratio ($M_{\\rm{ej}}\\sim 4-7\\,\\rm{M_{\\odot}}$, $E_{\\rm{k}}\\sim 7-8\\times 10^{51}\\,\\rm{erg}$).
