Got some of these husky bois painted up:
The weapons are all magnetized. I went with 2x Butcher Cannons (with a 3rd I didn't bother painting), 2x Soul Burner Petards, and a
DCCW\Power Mace as a counts-as Siege Claw. I didn't like the stock Siege Claws so I scratchbuilt my own power mace.
Fun models to assemble, the legs aren't too fiddly. I like the daemon engine concept and I wonder, if I attached the petards to the shoulders and put them on a larger base, if they could be counts-as Defilers. Kind of small for that, though.
