The Tierteiler Sword
This superb sword is considered one of the greatest tools to combat lycanthropes with without destroying the victims. This sword is usually incredibly sharp with a perfect, strait edge. The hilt is also made of finely polished silver and sometimes has an engraved crescent moon on the pommel or hilt.
This +4 Keen Humanoid (shapechanger) bane silvered longsword has a unique ability that wields great power over were-creatures and great mercy over their victims. Whenever anyone wielding this sword strikes an afflicted lycranthrope in either animal or hybrid form, it must make a Fortitude save with a DC of 20+Wielder's Str modifier. If this save fails, the creature, instead of taking damage is split into two individual creatures. One of these creatures is the person that was previously afflicted, but is now cured and the other is the animal form of which they were cursed to become at every full moon.
This new animal creature has as many hit dice as the previous victim added onto their normal animal HD. In all cases, each creature has half the hp of the lycanthrope before the split(unless this would bring the hp over the maximum, in which case they will simply have max).
This new creature is usually aggressive to those who split them from their humanoid host and will attack on upon separation(acting immediately, as though their initiative were right after the wielders).
