This spell was created and used to win a Nerundel Halls prank challenge a few years ago. You summon a 10-foot-by-10-foot swarm of mischievous fey creatures armed with various tiny weapons who fly around chaotically. The swarm understands and obeys your commands, and has the statistics of a predator swarm with the exceptions noted below.
The swarm has the fey type (instead of animal) and an Intelligence modifier of +0. Each round, the swarm deals 1d6 nonlethal slashing damage to creatures in its squares. If the swarm damages a target, it grants the benefit of harrying fire to the next creature that attacks that target. A swarm of fey pranksters does not have the usual distraction ability of a predator swarm; instead, all creatures sharing spaces with a swarm of fey pranksters must attempt a saving throw against a fey prank. The exact nature of the prank, and the required saving throw, is determined randomly:

d6	Prank	Saving Throw	Effect
1-2	Earworm	Will	Target is deafened for 1 minute.
3-4	Pie in the Face	Reflex	Target is blinded for 1 minute, but can remove this condition with a full action.
5-6	Tickle Attack	Fortitude	Target drops held item, chosen randomly.

Creatures who save against a fey prank are immune to fey pranks for 1 day. If the swarm is killed, all fey prank effects end.
