Curse of Yondalla

The curse of Yondalla was an especially powerful abjuration/alteration spell, granted only to followers of the hin deity Yondalla and reserved only for use against creatures guilty of destroying a halfling community or slaying innocent and defenseless halflings.

Effects
When cast, any creature or person affected by the spell was stunned and, over the course of the next minute, shrunk to Halfling size, as punishment for their deeds. Undead creatures without any sort of divinity were immediately destroyed while extraplanar creatures were banished to their home plane and unable to return for up to 100 years.

Usage
The curse could, in theory, be set upon any being of any age or gender. The only exceptions to this were; Halflings themselves, for obvious reasons; and children, of any race. This is because children, being already the size of halflings and (usually) in the same positions and alignments, were considered exempt from punishments inflicted upon foes of the race.

Components
This spell required verbal and somatic components and the use of the priest's holy symbol.
