Domain Focus
( Complete Divine, p. 80)[General]
You have mastered the subtle intricacies of the divine power you've devoted yourself to.
Prerequisite
Access to relevant domain,
Benefit
You can cast spells associated with one of your domains at +1 caster level. This benefit also applies to caster level checks to overcome a target's spell resistance as well as other variables such as spell duration. If you cast a spell from one of your nondomain spell slots, this feat does not help you, even if the spell also happens to appear on your domain list.
Special
You can take Domain Focus multiple times. Its effects do not stack. Each time you take the feat, it applies to a new domain to which you have access.
