Spells granted by your domain are -in addition- to those you would normally know from your cleric spell list. They do not count against your allotment of prepared spells. You would still get your normal cleric spells.
Do clerics need to prepare domain spells?
Each domain has a list of spells—its domain spells— that you gain at the cleric levels noted in the domain description. Once you gain a domain spell, you always have it prepared, and it doesn’t count against the number off spells you can prepare each day.
Can you apply metamagic feats to domain slot spells?
Domain spells cannot be used to cast spells spontaneously. Nothing there specifies one way or the other about metamagic. Applying metamagic to a domain spell, to make it use a higher level slot, does not in any way I can see break these rules. Yes, but only if you use the domain slot of the spell’s adjusted level.
How many domain slots does a cleric have?
If a cleric has at least one domain, then they gain one additional spell slot per level. This slot is separate from their normal spell slot progression, and can only be used to cast domain spells. A cleric gains one domain spell slot for each level of cleric spell she can cast, from 1st on up.
Why does a sorcerer have to apply a metamagic feat?
Because the sorcerer or bard has not prepared the spell in a metamagic form in advance, he must apply the metamagic feat on the spot. Therefore, such a character must also take more time to cast a metamagic spell (one enhanced by a metamagic feat) than he does to cast a regular spell.
When does a cleric gain a domain spell?
A cleric gains one domain spell slot for each level of cleric spell she can cast, from 1st on up. Each day, a cleric can prepare one of the spells from her two domains in that slot. If a domain spell is not on the cleric spell list, a cleric can prepare it only in her domain spell slot. Domain spells cannot be used to cast spells spontaneously.
