"+1 to caster level" from two different sources - Do they stack?

[reveal]

A player has a template which grants her a +1 to caster level. She is looking at buying the orange ioun stone, which also grants a +1 to caster level. Do they stack for a total of +2 to caster level?

Well, by the RAW, probably. If they don't have a type of bonus, they're unnamed bonuses, and thus stack. I don't recall seeing a type associated with any of the caster level bonuses I've seen, so I think they all stack.

If that bothers you, you could simply assign types to different sources. I'd say a template would give a racial bonus, and an ioun stone an enhancement bonus. I know I've had this conversation with a DM of mine before, and that's more or less what he decided. My question was in regard to the +4 CL from Practiced Spellcaster, and the +1 CL for casting [Evil] spells with the Evil domain.

Nothing say they don't, they're unnamed bonuses.

Actually, if you give them different types, then they definately stack. Only if they have the same type will they not stack.

That said, I don't see too much trouble from letting them stack. YMMV.

Caster levels stack. They just do.

If you want more detailed rules - they're unnammed bonuses, and unnamed bonuses always stack.
