Steel Mind Iron Logic

Use this Stratagem when an enemy PSYKER manifests a psychic power within 24" of one
or more of your GRAIA INFANTRY units.
Roll a D6; on a 4+, that psychic power is resisted
and its effects are negated.
Even the vile energy surges of the warp will be quieted
by the faith and undeniable logic that emanates
from the pure devotees of Graia.
