The most dramatic mutation is that of the Bull Centaur, which are well-documented in the tome, but of most interest to you is the record of the vivisection of a Sorcerer with special attention paid to the petrification that had begun upon his body. His feet and ankles were entirely of stone, and displayed evidence of grouting to repair cracks and chips, but the spread upwards was uneven, with blood vessels completely petrified to the knees and showing increased rigidity as high up as the thighs, even as the flesh above it appeared unchanged. But nothing above the waist showed any signs of the transformation, which provides you with quite a bit of food for thought.
Magic as you know it flows primarily through the arms and chest, and under very few circumstances would it concentrate in the lowest extremities of the body. But you know next to nothing of the nature of the magic the Chaos Dwarves use. Is it Divine Magic that flows from below? Is their strange God physical, rather than ephemeral? Would that be related to their affinity for fire and molten rock and metal? If it is Arcane Magic of some sort, and they deliberately push what they cannot expel downwards? Or does something in the nature of it make it obey the call of gravity, rather than flowing through the air like the Winds? Or is seeking a logical answer a fool's errand when dealing with Dark Magic?
Too many questions, not enough data.

Dhar calls to Dhar, and in sufficient quantities it would be more than enough to draw in warpstone-infused shot. The crank only needs to begin and sustain the reaction, not power it entirely, and after the first few bullets have been fed through the backpack mechanism, the magical draw on the rest can be tapped into to restore the flywheel to full power once more.
