Harridan

If this model is reduced to 0 wounds, roll a D6 before removing it from the battlefield; on a 5+, it lashes out in its death throes, and each unit within 3" suffers D3 mortal wounds.

At the start of the Shooting phase, you may choose to have the Harridan suffer D3 mortal wounds, but add D6 to the Strength of its bio-cannon for the duration of your current turn.

When moving a Harridan in the Movement phase, pick one enemy unit it passed over. That unit immediately suffers D3 mortal wounds. This ability may not target units composed entirely of CHARACTERS.

A Harridan can Fall Back in the Movement phase and still shoot and/or charge during its turn. When a Harridan Falls Back, it can even move over enemy INFANTRY models, though at the end of its move it must be more than 1" away from all enemy units. A Harridan can shoot even if there are enemy models within 1" of it, as long as all enemy models have the INFANTRY keyword. In this case, it can shoot the enemy unit that is within 1" of it or any other visible enemy unit that is within range and more than 1" away from any friendly models. In addition, the Harridan can move and fire heavy weapons without suffering the penalty to its hit rolls. Finally, the Harridan only gains the benefit of cover if at least half of the model is obscured from the bearer.
