The Limerick Curse

A curse that forces you to only speak in limericks. Since making limericks is often difficult, many people have decided not to bother and just become mute. This is also the reason why Arvendorith has no Silence spell, as the effects of this curse have the same effect on people.
The first known victim of this curse was Jorik Wizzard, who might have created it by accident during an experiment gone wrong. As an ancient wizard, however, he has had many centuries to adapt to the Limerick curse, and is one of few who can almost get by on limericks alone.
