Depends from many things. Item slots being most notqble. If they CAN'T wear body armor, their prot is way too low. They are missing boots already, losing the body would make them like the nagas of DomII, or Scorpion King without Earth.

Etherealness and Glamour is a nasty combination, though. Just Glamour would probably be enough, perhaps combined with a 1-hp ethereal "cloud of sand/dust/mist" ghost form like that of Oni of EA Oni Kings.
