Here's a feat I came up with for Clerics to get rid of their needing a decent Charisma score. What do you all think?
You understand that you possess far more strength of will than you do force of personality. As such, you have learned to use your force of mind in place of your force of personality.
Prerequisites: Wis 15+, the ability to turn or rebuke creatures
Benefit: Whenever you make a turn or a rebuke check, you may apply your Wisdom modifier to the turn/rebuke check, instead of your Charisma. As a side benefit, you may also choose to use your Wisdom modifier for Gather Information checks, instead of your Charisma.
