The Fate of Old Andrukah
Required Rank: 5
Effects: The Adeptus Astartes are as strong of mind as they are of body, their training and devotion to the Emperor hardening their wills against the perils of a deadly universe. Once per game session, a Battle-Brother may use the Mental Fortress ability to re-roll a failed Willpower Test to resist a Psychic Power or an attempt to subvert his will.
Improvement: At Rank 7 the Battle-Brother may add +20 to the result of the re-roll.
