Help with a feat...

[VarianArdell]

So, I was looking around this website, and stumbled upon this feat. As such, I was inspired to create the following feat:

Knowledge of the Saints [General]
Prerequisites: TBA
Benefits: You gain access to one of the following special abilities – turn/rebuke undead, domain access, or lay on hands. For the purpose of determining the effectiveness of these abilities, you are considered a cleric of your character level minus <some number> (in the case of turning/rebuking undead and domain access), or a paladin of your character level (in the case of lay on hands).
If you choose the domain access special ability and have the ability to cast spells normally, add the domain's spells to your list of spells known. You gain an extra spell slot of each spell level you can cast, which must be used to cast a domain spell. If you choose this special ability and cannot cast spells normally, you gain a spell-like ability that corresponds to each domain spell, useable 1/day, and is gained at the level a cleric of your character would normally gain access to that spell. For example, a 6th-level fighter with the Strength domain would be able to cast enlarge person, bull's strength, and magic vestment as spell-like abilities, each 1/day, and would gain the spell immunity spell-like ability at the next level.
Special: This feat may be taken multiple times. Its effects do not stack (but see below). Each time you take this feat, it applies to a different special ability.

Exception: It is possible to take this feat multiple times, selecting the domain access special ability multiple times. If you choose the same domain, its effects stack, granting you additional uses of each spell-like ability and domain ability. Domain abilities without a set number of uses per day do not stack with multiple selections.

Any suggestions on how to fix this? I'm no expert, but I think this may need a little help.

Clerics don't add domain spells to their cleric spell list, and as I understand it, can't cast them with regular spell slots. Since that feat gives you a domain spell slot, the "added to spel list" part should be removed from your feat.

No feat should grant you nine additional spell slots. Complete Divine already has rules for what a character without domain slots can do if they manage to acquire a domain. Use those instead.

You will need to add extensive prerequistes. Why? Many domains offer a bonus feat as their domain power (always a feat with minimal prerequisites that's available to any character at level 1). A feat that grants you another feat, plus nine spell-like abilities, is DRAMATICALLY more powerful than the secondary feat that was granted. The proper way to balance that is to add prerequisites that restrict your feat only to higher level characters.
