Before gaining the title of Warlock Engineer, Razzlok spent countless hours overseeing the mining operations of warpstone. Having seen the devastating effects of a falling piece of warpstone numerous times, his thoughts turned to mimicing nature. Secretly, Razzlok developed his "thrower of warpstone" at the expense of many of slaves' lives. One day, Skaven scouts reported sighting a small Dwarf party nearing Razzlok's mining operation. This was just the opportunity he needed to gain the Greyseer's favor. Razzlok, a small group of his fellow Clanrats, and his new invention met the Dwarf force. The Dwarfs were not expecting the vermin war machine that stood before them. Many a stunty died that day under the force of raining green stone. After hearing the reports, the Greyseer immediately ordered the production of Razzlok's Warpstone Thrower.

House Rules for Using this Crazed Invention in Your Games
The Warpstone Thrower costs 95 points and is a Rare choice. It has a crew of four Clanrats armed with hand weapons. Use the normal Stone Thrower rules found in the Warhammer Rulebook for guessing range.

Raining Warpstone. Unlike a normal Stone Thrower, the Warpstone Thrower uses Warpstone Templates (40mm round bases) instead of the small 3"-round template. Place one Warpstone Template down at the range guessed. Now, roll only the Artillery Die. If you roll a Misfire (yikes!), consult the Misfire Chart on p. 120 of the Warhmmer rulebook and determine the results. Otherwise, take the number you rolled and divide it by 2. The quotient will determine how many Warpstone Templates you actually generate (1-5 Templates). Once you have determined how many Templates you have, place each of them in contact with the initial Template already on the table. Now, roll a D6 and the Scatter Die for each Warpstone Template to see where they land individually. Any models even partially under a Warpstone Template will suffer a S3 hit with Killing Blow. All normal armor saves apply.
