Death Throes (Su) When a dark slayer is slain, its body implodes violently into nothingness, leaving its gear in a heap on the ground. All creatures within a 10-foot burst take 1d8 points of sonic damage and must make a DC 13 Fortitude save or be deafened for 2d4 rounds. The save DC is Constitution-based.
Magical Knack (Ex) Spellcraft and Use Magic Device are always class skills for dark slayers.
Soul Harvest (Su) When a dark slayer damages a flat-footed foe or a foe it is flanking with a melee touch spell or spell-like ability that deals hit point damage, the spell does an additional 1d6 points of damage and the dark slayer gains an equal amount of temporary hit points. These temporary hit points last for a maximum of 1 hour.
Dark slayers are a relatively rare sub-race of the dark folk imbued with malign energies that grant them a suite of deadly spell-like abilities beyond those normally accessible to their kin. They are usually encountered leading small bands of dark creepers, and seethe with barely concealed envy of the dark stalkers, ever scheming to displace them and claim a dark folk tribe of their own. Dark stalkers direct the slayers for their own ends, grooming them for use against enemies, ever ready to sacrifice a slayer in battle for an advantage, however temporary.
Unlike other dark folk, dark slayers embrace their evil impulses. Their pleasures extend more to murder and pain than to theft or mayhem. Dark slayers are obsessed with magical trinkets, coveting them above all else. Sadly, their obsessive need to fiddle and tinker often leaves their pretties broken or depleted.
Dark slayers stand just short of 4 feet tall and weigh 50 pounds. Most have a persistent tremor visible in their hands, stilled only when fondling a newfound magic item. Their skin is dead white, dry, and hot to the touch; their eyes are dark and narrow. Dark slayers wear salvaged rags like dark creepers do, but they discard the rags when they grow too tattered or foul-smelling.
