Ecto farming...hard or normal mode?

not only probably, they follow you and if you hide behind the spirit the lvl 25 dying nightmare will kill you, i tested it already cast ss on the moving att and it will pop the nm, hide behind benton, att and nm will follow but will get body blocked - if u do it the right way. u can kill nm easily once he gets it range w/ the att in front of benton, ss will triger (just dont forget to recast ps and sb and wand nm), i usally switch to 105 hp while fighting the lvl 25 nm.
