<Literally just shoot or stab one. The bullet was meant for Cayde, a Devourer round would've nullified resurrection anyway, but the Rifleman saw Sundance and shot her instead. The Fallen killed dozens of Ghosts during Twilight Gap by just popping them once they capped their Guardians. Cabal have crushed Ghosts during the Red War with their bare hands or stomped on them. Callum Sol stabbed right through a vacant Ghost shell with ease. As mentioned earlier, Felwinter killed a Ghost by just shooting it. It's really not that hard. They're a little durable, but a well-placed shot with anything capable of going through someone will go through a Ghost.>
