Ossefactor
From Warhammer 40k - Lexicanum
Ossefactors are Dark Eldar medical instruments that are used by haemonculi to manipulate their clients' bone growth[1] via "osteocytic impulsion waves".
The devices have also been pressed into military service and are wielded by haemonculi and wracks with deadly results. One blast from the weapon sees the victim undergo uncontrollable bone growth, with their skeleton suddenly sprouting spurs and spears that slay them instantly – and may even impale their brothers-in-arms.[1]
The Ossefactor was developed by the Haemonculi Coven known as The Hex after studying captive Black Dragons Space Marines and learning the secret of their bone growth mutations.[2]
