Swarm as Animal Companion?

[TaliesinCaster]

Are there rules for this? Seems like an awesome idea, but I can't find anything. I want to make a druid who's animal companion is a swarm of bees. Any help or advice anyone an provide is greatly appreciated.

It would be easier as a familiar. Especially if you are a beast-bonded witch. Casting a permanent reduce person on a scarlet spider familiar. Then at 7th level your familiar takes leadership. The spiders leadership score would tell you the cohort level. The cohort level would be the hitdice the swarm has.

There isn't any rules support for what you are asking, and it makes me sad because I want it too. Best you can do is ask your DM to work with you on it if you playing a home game.

I also like the idea of a swarm familiar. Swarms with improved evasion, what could possibly go wrong...

I want to create an arctic druid with a swarm of special snowflakes for his animal companion.

I've had this idea for a swarmshaper for a while now. I really need to start writing it, but gotta wrap up my other archetype first.
