A question. Can a Druid turn into a rat swarm? In the MM, it's listed as a tiny animal. (We're assuming a high-enough level Druid for changing into tiny animals.)
If so, can he then cast Reduce Animal on himself and become a fine swarm (even though he can't wild shape directly into a fine-sized animal)?
We're trying to figure out if this is doable. The main question is, is a swarm considered a single animal for this purpose?
As others have said, it's not possible by the rules. However, I'm going to toot my own horn for a bit, so here's my home-brewed feat:
SWARM SHAPE [General]
You can assume the form of a swarm.
Prerequisites: Wis 19, Wildshape (Tiny) class ability, Knowledge (nature) 13 ranks
Benefits: You can use your wildshape ability to assume form of any swarm composed of Tiny animals. You gain all the traits of the swarm subtype (half damage from slashing or piercing weapons, immunities, etc.). If you're reduced to 0 or less hit points while in the swarm shape, you are immediately forced byck to your natural form.
Special: If you posess the abilty to wildshape into creatures of type other than Animal (and you meet the feat prerequisites), you can then assume shape of swarms consisting of Tiny creatures of those types.
While swarm subtype has some nice benefits, it also has certain drawbacks; for example healing becomes very difficult unless you have
mass cure X wounds (or similar) spells available (otherwise you'd be healing a single rat in the swarm, which isn't going to do any good, really), you receive +50% damage from area attacks (meaning every
fireball that hits you is automatically considered empowered), and at higher levels you'll do precious little damage to your opponents (swarms usually deal small amounts of damage, but they deal it automatically every round, however you can't cast
(greater) magic fang on a swarm, so you'll have only the swarm's natural, non-magical weapons available), etc.
Regards.
