The wraith returns once more with its scythe, you step forwards and slash, striking true, although the wraith retreats out of range again before you can strike a second time (evasive reflexes+Rolibar's gambit). The scythe comes for a third time at your heart, and then the wraith strikes at your head with the reverse end, before fading once more into the walls).
"Scythe" incorporeal touch: (1d20+49)[53]
Concentration check (DC=your AC, probably automatic success): (1d20+71)[77]
Damage: (8d6+184)[211] and (3d6)[10] cold damage. DC 47 fortitude save or take (1d8)[7] con drain.
"Hilt" incorporeal touch: (1d20+49)[63]
damage: (2d6+33)[41]
This also does d8 con drain if you fail a DC 47 fortitude save. I forgot to add it in here, although as you have a 95% chance of passing, just roll the save, and I'll roll the damage if you fail.
Both attacks ignore DR.
