Engineer Gertak Hellor was faced with the problem of destroying a seemingly impenetrable and unapproachable Skaven Warren entrance. The small fort was well-placed on high ground within a narrow cavern and armed with some experimental type of Jezzail that was working a little too well for Gertak's liking. Ironbreakers had been about the only troops able to withstand the sheer amount firepower, but with no back up, they were forced to retreat when they reached the walls protected by hordes of Skaven. A plan began to form in Gertak's mind for an armoured contraption capable of withstanding the Jezzail fire that could deliver a bomb blast to breach the fort. Then, under the cover of massed Thunderer fire, the Dwarfs could drive home the attack without worrying about siege equipment. The Hellor, as his inventions is now known, worked like a charm. The contested Skaven fort fell mere minutes after the devastating blast.

The Hellor's sturdy steam-driven tracks plow through all intervening terrain and obstacles with implacable, clockwork-guided purpose. The armoured hull is reinforced to repel nearly all types of standard missile fire. Upon reaching its target, the Dwarf operator yanks a length of chain which extended behind the device as it travels. One good tug and "Blam!," it's all over. Of course, during its trek toward the enemy, a Hellor is quite vulnerable to suicidal attempts by the enemy to pull the chain prematurely. For this reason, it is often used against opponents dug into defensive positions.

House Rules for Using this Crazed Invention in Your Games
A Hellor and Dwarf Engineer are deployed together at the start of the game. The Hellor counts as a Rare Choice.

Send in the Hellor. The Hellor creeps forward steadily up to 8" a turn. Thus, it may never charge or march. It may change direction by up to 45 degrees at the start of its move. The Hellor ignores all Difficult Terrain penalties and plows through any obstacles up to 2" in height, including enemy models and units.

Ka-Boom! A Hellor may be detonated at any point during its move, so long as there is an Engineer attached to the end of the chain attached to the vehicle. If the Engineer has been slain, then a regular Dwarf Character may attempt to detonate the device by moving into contact with the chain and rolling a 4+ on a D6. Only enemy Skirmishers and individual enemy Characters may try and detonate the device prematurely by moving into contact with the rear of the Hellor and rolling a D6 for each Attack in their profile. If a 6 is rolled, then the saboteur has succeeded. Work out the blast as described below and remove any models in contact with the Hellor — they have been vaporized!

When the Hellor is detonated against a fortification, roll on the Siege Damage Chart six separate times against the particular section targeted. To determine the damage of the blast, roll a D6 and add 10. If the Hellor is detonated against any other type of target or is destroyed, place the 5" blast template over the Hellor and work out 6 S10 hits against any models touched, even partially. No armor saves of any kind are allowed.
