Not sure if it's helpful, but here's what is listed in the 4e version of Digging for Lies.

When you reach out, you aren’t sure whether what you see is close enough to touch, or as distant as the stars in the night sky.
Stage 0: The target recovers from the disease.
Stage 1: Initial Effect: The target gains vulnerable 5 psychic. If knocked unconscious by psychic damage, the target gains a Mind Scar (see below).
Stage 2: As above, plus the character grants combat advantage, and suffers a –2 penalty to attack rolls.
Stage 3: Final State: As above, plus if the character makes an attack and misses all targets, the character is dazed until the end of his next turn.
Check: At the end of each extended rest, the target makes an Insight check if it is at stage 1 or 2.

11–15: No change.
