Toxic Miasma

Once per game, in any Assault phase, a unit with this biomorph can unlease its toxic miasma. If it does so, at the Initiative 1 step, all enemy units engaged in close comabt suffer a number of hits equal to the number of models from their unit in base contact with any model from the Tyranid unit unleashing the toxic miasma. These hits are resolved at Strength 3 AP- and have the Poisoned and Ignores Cover special rules.
