They Came From Below
(Rule)Description: All units in this Formation must be placed in Reserve. Make a
single Reserve Roll for the entire Formation. When the Formation arrives from Reserve, deploy
the Trygon Prime first, by Deep Strike, using its Subterranean Assault special rule. Once the
Trygon Prime's final position has been established, the Formation's three Ravener Broods
immediately enter play.
Place the Ravener units so that all of their models are wholly within 6” of the Trygon Prime's
base and in unit coherency. These models cannot be placed within 1” of enemy models or
within impassable terrain; if any models cannot be placed, these excess models are removed
as casualties. The Formation's Ravener Broods cannot move in the Movement phase or charge
on the same turn they arrive, but can shoot or Run.
The Formation's Trygon and Mawloc enter play via Deep Strike as usual.
