The mutant's hands or paws are turned into ornate weapons marked with the rune of the mutant's patron Chaos Power. A creature without arms also suffers the effects of the Quadrupd/Biped attribute. Roll a D6 to determine type: Add one to the mutant's S when it attacks with a Beweaponed Extremity, but reduce its I by -10. Treat the mutant's opponent as if it had one less armour point on every hit location. Having Beweaponed Extremities means that the mutant cannot use any other weapon types, including missile weapons. The mutant's Dex is reduced to 0. Finally, add one to the mutant's fear points.
