Sanctioned Psyker- Telepath - Warhammer 40K: Rogue Trader Database

Every time the psyker deals mental damage from any source other than Aftershock, the target suffers half as much mental damage at the end of its next turn.

Enemies that have failed a Willpower resistance test against any of the psyker’s psychic powers will suffer an additional +(3 + 3 x psy rating) mental damage every time they suffer mental damage until the end of combat.

Whenever the psyker kills an enemy with a psychic power dealing more damage than wounds of the target, the excess damage will be dealt to the enemy closest to the target.

After every sixth use of a psychic power by the psyker, all enemies gain a stacking —5 penalty to all characteristics until the end of combat.

Enemies that have taken damage from the psyker at least once suffer a —20 penalty to all resistance test against the psyker until the end of combat.

Any time an enemy becomes a target of any particular psyker ability for the first time, this enemy suffers a -5 penalty to their Intelligence and Perception, and the psyker’s Intelligence and Perception increase by +2 until the end of combat.

Enemies that become targets of the psyker’s psychic powers gain a stacking -5% penalty to their dodge and parry until the end of combat.

Enemies, currently inflicted with blinded, stunned, immobilised, or prone effects by the psyker, suffer +10% more damage
