Enemies in the aura take a -2 penalty to melee and ranged attack rolls.
A flying bat swarm does not provoke opportunity attacks when it moves.
The swarm can occupy the same space as another creature, and an enemy can enter its space, which is difficult terrain. The swarm cannot be pulled, pushed, or slid by melee or ranged attacks. It can squeeze through any opening that is large enough for at least one of the creatures it comprises.
