Can a paladin take Sacred Summons?

[Velithin]

I'm thinking about doing a three level dip into paladin, and was wondering if that would let me qualify for sacred summons. My character is a conjurationist, and since my friends don't optimize at all (we usually focus on RPing more so than combat), I would like to make use of Sacred Summons. The downside is that I don't have anything besides the advanced books, the core rulebook, and the ultimate books. If paladin doesn't work, what suggestions do you guys have?

As a side note, if I go one level in cleric with LG, would it be a good idea to take combat reflexes, and have reach as a defensive mechanic to fall back on?

This is aimed at high level play, by the way, and again, we don't much care about the shenanigans that can be pulled. We just want to have fun.

If you aren't limiting yourself to your books.

If not, a one level dip in Cleric seems fine.

There is no reason why Paladin wouldn't work if that's your wish.

Would the paladin's aura be restricted to only good templated creatures, or is it good and law?
