MALEVOLENT COVENANT
Use this Stratagem in your Psychic phase, after a WORD BEARERS PSYKER unit from your army fails a Psychic test. The power is automatically manifested by that PSYKER unit at the minimum required warp charge value and without a double having been rolled, and cannot be resisted by a Deny the Witch attempt. After resolving the effects of the psychic power, that PSYKER unit suffers 1 mortal wound.
SOULS OF IRON
Use this Stratagem in your opponent’s Psychic phase, when an enemy PSYKER model manifests a psychic power within 24" of an IRON HANDS unit from your army (after any Deny the Witch attempt). Roll one D6; on a 4+ that psychic power is resisted.
Can you use souls of iron to resist a psychic power which has been automatically manifested with malevolent covenant ? I say no, because souls of iron requires a DTW attempt, and malevolent covenant says it cant be resisted by a DTW attempt.
