Madness domain

The Madness domain was a deity domain that granted madness-related spells to a cleric or certain divine spellcasters like clerics devoted to a god of madness. Once the gods Cyric, Ghaunadaur, and Tharizdun laid claim, the madness domain began spreading their blessing to their followers.

Cyric "The mad god" was an ever lasting void of madness. His insanity grew indefinitely, sometimes seeming to bring him back to what might be sanity, thus cementing the depth of his madness.

Ghaunadaur resided alone in the Dismal Caverns, letting insanity claim him. In his madness, he released abominations that carried madness wherever they appeared.

Mortals wanted to keep Tharizdun's very name from their minds out of fear. His followers were given to extreme actions and inner torment, as their god existed to bring about the end of all things. Once a day, a devoted spellcaster could gain the clarity of madness and become more wise or strong willed.

Power Of Madness domain
Any divine caster that worshipped a god that claimed the madness domain could channel the madness Domain. Divine casters who chose to channel the madness domain were more skilled at deception. When a caster aligned with the madness domain used an ability that harmed an enemy, their channelling of the domain could cause their target to be less accurate for a short period of time.
