Cloudkill

An unforgivable curse. It summons a heavy, deadly poison cloud that creeps along the ground, choking the life from all creatures trapped within it.

 According to legend, this magic was developed by an infamous wizard to annihilate a race he hated. The cloud spreads following the terrain, ruthlessly suffocating those with nowhere to hide;

 the reason it is unforgivable is because it is magic where one cannot even remember all the faces of those they killed.
