Sorry I didn't get back to you on this, Witt. I just checked and I have 3 heavy flamer bits from the Baneblade sprues (I should have four, but can't find the fourth), and I don't know if you can use these, but I also have 3 heavy flamer bits from chimera's also.
A tiny portion of humanity turned its back on mankind in the waning days of the last Golden Age. Over one and a half centuries later, the PHR has emerged from the shadows as an unrecognisable civilisation, its people irrevocably changed. They are no longer simple human beings, they are post-humans - cyborgs.
