Terrestrial Disregard
(Rule)Description: Instead of using the normal rules for Subterranean Assault, when a model with this special rule enters play via Subterranean Assault, place an Apocalyptic Blast marker (10") anywhere on the battlefield that is at least 1" from any enemy model, battlefield edge or piece of Impassable Terrain and then scatter that marker (see the Scatter rules on page 152 of the Horus Heresy: Age of Darkness rulebook).
If the marker’s final position is within 1" of an enemy model, any battlefield edge or a piece of Impassable Terrain, then the controlling player’s opponent may move that model to any position within 18" that is more than 1" from any enemy model, battlefield edge or piece of Impassable Terrain. If there is no suitable position within 18", then the model may be repositioned by the controlling player’s opponent anywhere on the battlefield that is more than 1" from any enemy model, battlefield edge or piece of Impassable Terrain.
Once the final position of the marker has been determined, the controlling player may place the model with this special rule on the battlefield so long as the centre of the marker is underneath part of the model’s hull, and the model remains more than 1" away from any enemy model. After the model has been placed, each Fortification within 6" of it immediately suffers D6 Str 10, AP 2 Hits, and nearby units suffer one S10, AP 2 Hit for each model within 6" of the model. Any unit that suffers one or more Hits from this effect must take an immediate Pinning test.
The area under the Apocalyptic Blast marker (10") is treated as Difficult Terrain and Dangerous Terrain for the remainder of the battle.
