Abhor the Witch, Destroy the Witch

This vow affects all Black Templar units (including vehicles) and happens after deployment, but before Scout moves and rolling to see who takes the first turn. Models that may Infiltrate must be set up with the rest of the army. If there is a psyker in the enemy army (even if the psyker is not deployed on the table), each individual unit must make a Consolidation move D6" towards the nearest visible enemy unit. Crusader seals affect this movement as normal, even if the unit or model is inside a vehicle. If the Concealment mission special rule is in effect, the army immediately ceases to benefit from it. 

In addition, any Psychic powers targeted against Black Templar units or characters (or which includes them in its area of effect) are nullified and will not work on a D6 roll of a 5+ (only roll once for each power, even if it affects several units). Minor psychic powers have no effect on Black Templar units or characters at all.
