Temptation Domain

As a cleric of temptation, you worship a god of a desire that people have. Your god pulls on people's desires so they give in to the temptation. They could be gods of love, money, knowledge, power, or anything that might cause someone to make a bad decision in order to gain it.  Gods such as Aphrodite, Set, Erythnul, Shinare, and Tiamat all fall into this domain. If your DM allows clerics to worship powerful fiends as well, then Mammon and Graz'zt are also good examples. A Temptation god is normally constantly weaving through people's minds, persuading them to give in to their desires. A cleric of these gods would normally do more of the same, making people believe that "just once won't hurt."

Charismatic Casting

Your spellcasting ability for your cleric spells becomes Charisma instead of Wisdom. You prepared spells and Spell Save DC use your Charisma modifier instead of Wisdom. In addition, if you have a cleric ability that uses your Wisdom, you now use it with Charisma.
