While this model is leading a unit, you can re-roll Advance and Charge rolls made for that unit.

At the start of your Shooting phase, one PSYKER with this ability can use it. If it does, select one enemy unit within 12" of and visible to that PSYKER and roll one D6: on a 1, that PSYKER’s unit suffers D3 mortal wounds; on a 2+, until the start of your next Movement phase, each time an attack targets that enemy unit, improve the Armour Penetration characteristic of that attack by 1.
