The rogue incapacitates a target, who takes no damage from the attack but is stunned for 4 seconds (duration adjusted by target rank).
Stun duration is modified by party size. The exact formula is very similar to the Mind Blast, with base 4 seconds duration instead of 3: (4.0 + (4.0 - (Party Size))) * (Target Rank Duration Modifier). Sources: talent_constants_h.nss, talent_singletarget.nss.
Conjuration time: 1s.
20 threat is supposed to be drawn from the target. As of patch 1.02, no threat is drawn.
