To fire the Deathshrieker, take a small counter or similar marker (no more than 1" across) and place it anywhere completely within the war machine's line of sight, outside of the Deathshrieker's minimum range and within its maximum range.

This target point cannot be placed over friendly units or enemy models from a unit that is engaged in combat with friendly units. The weapon may however strike friendly targets by mistake.

Once the marker has been placed, roll for scatter using a Scatter dice and an Artillery dice. If a Misfire is rolled on the Artillery dice, roll on the Black Powder Misfire Chart in the Warhammer rulebook.

If there is no misfire and a 'hit' is rolled on the Scatter dice, the rocket lands on its intended target and the number on the Artillery dice is ignored. If an arrow is rolled, move the target marker a distance in inches equal to the result on the Artillery dice in the direction shown on the Scatter dice.
