Bind Loup-Garou

Created by the blood magician Lhyle Lelouche', this spell permanently binds any lycanthrope or were-creature to it's animal form permanently. Upon casting this spell, you force one or more lycanthropes within 25 feet of each other to remain in their animal form. After casting, the targets of this spell spend at least half of the next 1d4 days in their humanoid form whether they want to or not, while in their fleeting humanoid form, they adopt the mannerisms of their animal form in the way of brutishness, violence, secrecy, and the like. After that, they undergo their final transformation into their beast form and remain in that form forever, even after death. Upon realizing they cannot transform back, affected creatures normally spend all of their time in the wilds, forever living as a beast until death.

A Wisdom saving throw DC 20 is required from the target to avoid this fate, failure means the target is doomed.

Magic that removes curses has a 50% chance to free the target from their fate. Only one attempt can be granted from each cleanser from a caster level at or above the required level to cast any spell that removes curses. The GM can expand this by casters of different faiths, oaths, and magical sources.

Any creatures affected by this spell are able to kill the caster if prompted, however, the death of the caster does not break the curse. 

Casting this spell at any spell slot higher than 4th level adds another 5 feet to the target range.

This spell is not class-locked. Any entity able to comprehend and carry out the components stated from either a spell tome or taught by one who knows this spell already can use it. Common folk who come across this spell use it to aid in their daily task for both personal and impersonal gain depending on the alignment of the caster.
