Psychic Discipline: Biomancy A Psyker with this Discipline gains all the listed Powers, weapons and other special rules, as well as the Aetheric Lightning Psychic Weapon.
Biomantic Augmentation (Psychic Power)
Biomancer’s Rage (Psychic Weapon)
Rending (X) If a model has the Rending special rule, or is attacking with a Melee weapon that has the Rending special rule, there is a chance that their close combat attacks will strike a critical blow. For each To Wound roll equal to or higher than the value listed, the target automatically suffers a Wound, regardless of its Toughness. The controlling player may choose to resolve these Wounds at AP 2 instead of the weapon’s normal AP value.
Similarly, if a model makes a Shooting Attack with a weapon that has the Rending special rule, a To Wound roll of equal to or greater than the listed value wounds automatically, regardless of Toughness, and is resolved at AP 2.
In either case, against Vehicles each Armour Penetration roll of equal to or greater than the listed value allows a further D3 to be rolled, with the result added to the total Strength of the attack. These Hits are not resolved at AP 2, but are instead resolved using the weapon’s AP value.
For example, a model with the Rending (5+) special rule that rolls To Wound against a non-Vehicle model will wound automatically on the roll of a 5+, and the attacking player has the choice of using an AP value of 2 instead of the AP value of their weapon.
Psychic Focus Before making any To Hit rolls with this weapon, the Psyker must make a Psychic check. If the Check is passed, then the Psyker may attack as normal using the profile shown for this weapon. If the Check is failed, then the Psyker suffers Perils of the Warp, and if the model is not removed as a casualty then it may attack as normal but may not use this weapon.
Force Any Psyker with a weapon or ability with this special rule may choose to make a Psychic check before making any attacks with that weapon or resolving the ability. If the Check is successful then the Strength value of any attacks made is doubled. If the Check is failed then Perils of the Warp is resolved targeting the unit containing the model that failed its Check. If the Psyker survives Perils of the Warp then it may attack as normal.
