Spread your toxic presence across every world that your army comes to with the Miasmic Malignifiers. Made up of the main chimney and the smaller pox furnace, it's a great way to bring the blessings/curses (delete as appropriate) of Nurgle to your tabletop. It's also designed to sit neatly atop the Sector Mechanicus Ferratonic Furnace, making a truly immense engine of corruption.
This 55-piece plastic kit makes one Miasmic Malignifier, a Death Guard-specific piece of terrain for use in games of Warhammer 40,000.
