Blood Begets Blood This Stratagem can be purchased by any Legio Osedax player. Play this Stratagem when a friendly Legio Osedax Titan suffers Catastrophic Damage. After resolving the effects of the Catastrophic Damage, every friendly Legio Osedax Titan may immediately make a single weapon attack. This attack must be made against the closest visible enemy unit. Increase the Plasma Reactor level of any Titan that makes an attack in this way by 2, in addition to any other advances associated with weapon fire.
