Domain question for a non-domain divine caster.

[Buufreak]

I rolled together for a specific purpose a Favored Soul 9/ Paladin 2/ Singer of Concordance 5. At SoC 2, I gain a bonus domain, which a FS doesn't have to begin with. How do I treat this?

Then you've gotten your first domain. You have access to the domain granted power, and the spells are added to your spontaneous caster's class list as normal spells, but can only be cast once per day each.

Complete Divine page 20 has the complete rules on this. Basically if something gives you the granted power of a domain you get that, but if it gives you the bonus spells you don't get that.
