Paroxysm

Paroxysm has a warp charge value of 5. If manifested, choose an enemy unit within 18" of
the psyker. Until your next Psychic phase, that
unit must Fight last. If the target unit has an
ability that allows it to fight first in the Fight
phase, it instead fights as if it didn't have this
ability. If both players have units that cannot fight until all other units have done so, then alternate choosing which of those units to fight with,
starting with the player whose turn is taking place.
