Pack Lord and Celestial Servant

[Cerwin]

I'm running a game and I have a player that is a pack lord druid and he as his first level feat was celestial servant. With this combination would the celestial template be applied to every animal companion or would it only apply to one. My player is trying to say it should go on every companion and I feel that would make it way too powerful for a single feat.

It's ambiguous, the feat doesn't really spell out how it even interacts with multiple class features, but I say it should work, pack lord is a crummy archetype anyways past level 5 or so.

I think it would apply to every companion.

If it seems strong, note that other than a small amount of resistances (which a Pack Lord would need anyways, so his pets don't get destroyed by an area effect spell), the benefits are HD related, and because the druid has to split his effective druid levels among his pets, they are not likely to reach the increased resistance and DR/evil threshold for a while.
