In each friendly Shooting phase, even when engaged in close combat or when fleeing, the Doomwheel automatically unleashes bolts of warp lightning.
Each warp lightning bolt will automatically hit the nearest unit (friend or foe), regardless of line of sight and direction.
The Warlock Engineer may choose to take a LD test in an attempt to stop the Doomwheel from firing. If the test is failed, the machine fires as normal.
Roll an Artillery dice to determine the S for the bolts, measuring from the Doomwheel's base. If the closest unit dies from the first bolt, the second bolt hits the next closest unit in range, and so on. If two targets are equidistant, the owning player may choose which unit is struck.
If you roll a misfire result something has gone awry. No more shots are fired this turn and you must roll immediately on the Doomwheel Mishap chart.
