Tasha's hideous laughter

Tasha's hideous laughter was an enchantment spell that caused its target to fall into crippling bouts of laughter.

Effects
The target of Tasha's hideous laughter perceived everything as extremely funny and laughed so uncontrollably that it became impossible to even stand up. The effect of the spell lasted for up to one minute, as long as the spellcaster kept concentrating on the spell or until the target managed to shake off the effect. Ending the spell's effect was also easier if the target was injured in any way.

Components
The spell required verbal, somatic, and material components. The materials required were a small feather that needed to be waved in the air and tiny tarts.

History
The spell was attributed to the Oerthian archmage Iggwilv, during an early time in her career when she was known as Tasha.

By the late 15 century DR, the spell was commonly used throughout Waterdeep as a security measure against burglars, usually coupled with a glyph of warding cast on rooftops.

The spell was commonly employed by nilbogs. It was also known to some cloud giant spellcasters and could be innately cast by powerful eladrin who resided in the Feywild.

Additionally, Tasha's hideous laughter was favored by cultists of Yeenoghu and was considered a signature spell of his followers.
