We present the discovery potential for a TeV-scale charged Higgs using 100--300 ${\rm fb}^{-1}$ of 13--14 TeV LHC data. While $H^+$ is predicted by a generic two Higgs doublet model, strong phenomenological constraints restrict our focus to type-II models in the alignment limit. We examine $H^+$ produced in association with, and decaying to, 3rd generation quarks ($pp\to \bar{t} b (H^+\to t \bar b)$). The $H^+\to t \bar b$ final state gives $H^+$ superior reach (compared to its neutral $H/A$ siblings) in the critical ``wedge'' region ($\tan(\beta) = 2 \text{--} 20$), where the dominant neutral coupling transitions from $y_t^{}$ to $y_b^{}$. We tag massive $H^+\to t\bar{b}$ by pairing a high-efficiency boosted-top tag with our low fake-rate $\mu_x^{}$ boosted bottom-jet tag (which rejects light jets ${\sim}10$ times better than prior $b$~tags). The success of the $\mu_x^{}$ tag to suppress the QCD background for $H^+$ events further validates its usefulness in the high-$p_T^{}$ regime (as has already been demonstrated in generic $W^\prime$ and leptophobic $Z^\prime$ searches).
