Devout Push

When: Your opponent's Shooting phase, just
after an enemy unit has shot.
Target: One Adeptus Astartes unit from your
army that had one or more models destroyed
by those attacks.
Effect: Your unit can make a Normal move of
up D6", but must end that move closer to the
shooting enemy unit. If the Abhor the Witch,
Destroy the Witch vow is active, your unit can make
a move up to 6", and if it does, then it must move
closer to that unit or the nearest Psyker unit.
