Domain Focus

(Complete Divine, page 80, DnD 3.5)

[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.
