We study the LHC sensitivity to a ${W}^{\ensuremath{'}}$ produced via bottom and charm quarks and decaying to $\ensuremath{\tau}$ flavor leptons in the mass range 200--1000 GeV. We show that the extra $b$ quarks necessitated by the production mechanism can improve the background rejection compared to an inclusive analysis relying solely on $\ensuremath{\tau}$ tagging and ${E}_{T}^{\mathrm{miss}}$. We present prospective limits on the couplings and compare them to the best fit to the $R({D}^{(*)})$ anomalies in $B$-meson decays.
