Mad Faith
(Heroes of Horror, page 123, DnD 3.5)
[Tainted]
Your depravity has twisted the connection between you and your patron deity. You suffer flashes of insight interrupted by flashes of madness.
Prerequisite
Ability to cast 1st-level divine spells, mild depravity
Benefit
You gain a bonus 1st-level divine spell per day. If you have moderate depravity, then you also gain a 2nd-level divine spell per day. If you have severe depravity, then you also gain a 3rd-level divine spell per day. However, it takes twice as long for you to pray for your spells each day.
