Brass Scorpions are daemon engines dedicated to Khorne, often used by Chaos commanders to spearhead a frontal attack. It is heavily armored against both conventional ordnance and psychic attack with its daemonic iron and brass armor covered in powerful runes of warding. Fully armed with a succession of medium range weapons like its rapid fire 'Stinger' tail and devastating Demolisher Cannon, it however excels at close range where it can bring its heavy Flamethrowers and powerful claws to bear.
